Abstract  
Traditional medicine helps manage and treat various illnesses worldwide, particularly in Africa and Asia. For example,  
Traditional Indonesian Medicine (Jamu), Traditional Indian Medicine (Ayurveda), and Traditional African Medicine use  
a range of indigenous herbs to treat health conditions like fevers, malaria, diarrhea, diabetes mellitus, Asthma, and  
hypertension. Alkaloids, flavonoids, saponins, terpenoids, and polyphenols are bioactive substances with anti-  
inflammatory, antibacterial, and antioxidant effects in plants. The Fabaceae family consists of flowering plants, peas,  
legumes, woody trees, and shrubs. Fabaceae plants are widely used across Africa and Asia for traditional medicinal  
purposes. In addition, Fabaceae plants have significant economic value as a source of wood for the timber industry.  
This review highlights extraction methods, isolated molecules, and antimicrobial and antioxidant activity of Fabaceae  
plants found in Africa and Asia. We also detailed secondary metabolite molecules extracted from Fabaceae plant  
body parts and their identified bioactivities. This review compiles scientific information on the phytochemicals and  
pharmacological properties of plants in the Fabaceae family that could be useful for future drug candidate  
investigations.

Introduction  
has revealed alkaloids, flavonoids, tannins,  
steroids, triterpenoids, and cumarines [13].  
Plants are systematically classified into phylum,  
class, family, genus, and species, enabling  
researchers to target specific groups, such as  
Fabaceae, for bioactive compound investigations  
[1]. The Fabaceae family of plants, also called  
Lugiminosae, has a diverse composition of about  
20,000 species of plants distributed in about 727  
genera [2,3]. The Fabaceae family is the third-  
known largest family of higher plants in the Plant  
Kingdom, with members mostly being flowering  
plants such as legumes, peas and trees, shrubs,  
and herbs (Figure 1) [4].  
Secondary metabolites, which have various  
structural variations and are non-nutritive  
chemical  
substances,  
oversee  
secondary  
metabolic mechanisms in plants, including  
communication and defence [14]. Secondary  
metabolite compounds are biologically active  
anti-inflammatory,  
anticancer,  
antibacterial,  
antimalarial, and antioxidant agents [15].  
Recent  
advances  
in  
phytochemical  
and  
pharmacological research have highlighted the  
potential of secondary metabolites as single  
therapeutic agents or in combination for drug  
development [16]. The efficiency of extracting  
and isolating these compounds from plant  
sources largely depends on the choice of solvent  
and extraction technique. Traditional methods,  
such as maceration, Soxhlet extraction, and  
distillation using polar solvents, remain widely  
used [17]. However, recent studies have explored  
alternative approaches, including ultrasound-  
assisted extraction (UAE), microwave-assisted  
Human diseases and ailments are traditionally  
treated with various plant species from the  
Fabaceae family [5]. Fabaceae plant species are  
in many parts of Africa and Asia because they  
adapt to different climatic and environmental  
conditions  
suitable  
for  
wider  
ecological  
distribution [6,7]. Traditional medicine plays a  
vital role in primary healthcare across Africa and  
Asia, where Fabaceae plants are widely used due  
to their diverse bioactive compounds [8].  
Compared to Asia, Africa is limited in terms of  
well-documented literature on phytochemical,  
pharmacological, and bioactivity studies of  
medicinal plants despite reports indicating that  
80% of the population on the continent relies on  
some form of traditional medicine to treat  
ailments [9].  
extraction  
(MAE),  
and  
pressurized-liquid  
extraction (PLE) [18]. These non-conventional  
techniques, which utilize pressure and wave-  
based energy, offer significant advantages in  
terms of extraction speed and reduced solvent  
consumption [19].  
Fabaceae species have been widely studied for  
their secondary metabolites and bioactivities,  
There is a vast potential to investigate the  
phytochemical constituents and pharmacological  
potentials of plants in Africa and Southeast Asia.  
For example, Senna alata, a shrub of the  
Fabaceae family and Caesalpinioideae subfamily  
found in Ghana, Nigeria, Niger, and Togo, has  
shown promising evidence of antimicrobial and  
analgesic properties against bacterial and  
inflammatory diseases [10-12]. Similarly, Cassia

antimicrobial,  
and  
antioxidant effects [20]. Phytochemical analyses  
have identified compounds such as alkaloids,  
flavonoids, saponins, tannins, steroids, and  
terpenoids in various plant partsleaves, bark,  
stems, and roots (Figure 1) [21,22]. Structural  
characterization using mass spectrometry and  
NMR has confirmed these metabolites (Figures  
2a2c) [2325]. Several extracts from Fabaceae  
siamea  
of  
the  
Fabaceae  
family  
and  
Caesalpinioideae subfamily is traditionally used  
in North Sumatra, Indonesia, as an antimalarial  
plant. Antimalarial screening of C. siamea has  
shown potency for antimalarial activity, and

In this review article, we discussed extraction  
methods applied in secondary metabolite  
isolation from plants of the Fabaceae family. We  
categorised the methods as (1) maceration, (2)  
soxhlet extraction, and microwave-assisted  
extraction. In addition, we discussed a variety of  
molecules extracted from stems, barks, leaves,  
stem barks, and roots of Fabaceae plants found  
mainly in Africa and Asia. We also identified  
critical reports in the literature on the bioactivity  
of the Fabaceae family plant extracts. The  
perspectives given in this review could be useful  
powered sample material in a vessel that can be  
covered; (ii) mix the sample material with an  
appropriate solvent; (iii) agitate the mixture; (iv)  
cover and allow the vessel to stand for a target  
duration [29]. The crude extract is then separated  
from the solute sample mixture by filtration.  
Polar solvents like water, methanol, and ethanol  
are popular choices in maceration extraction for  
phytochemical studies [30]. These are capable of  
dissolving  
plant materials (solubility)  
and  
separating phytochemicals from the extracellular  
parts of plants (selectivity). Despite some  
disadvantages of maceration, like long extraction  
process, large amounts of solvent consumption,  
and low extraction efficiency, maceration  
extracts thermally labile compounds without  
degradation [31].

Extraction Methods  
The growing interest in secondary metabolites  
for applications in the fine chemical, food,  
beverage, nutraceutical, and pharmaceutical  
industries has prompted the development of  
advanced extraction techniques to improve their  
Masruri et al. extracted 0.57% crude extract from  
the 3.5 Kg waste bark of Paraserianthes falactaria  
L. (sengon) macerated in n-hexane for 24 h [32].  
Triterpenoids were identified as the major  
constituent with alkaloids and flavonoids. To  
extract the oil, Baihaqi et al. macerated 100g of  
waste Paraserianthes falcataria bark for two days  
in 70% ethanol [33]. Total phenolic (TPC) and total  
flavonoid contents (TFC) were reported to be 10  
mg GAE/ g dw, 1.6 mg RE/ g dw, and 7.3 mg GAE/  
g dw, respectively. After three days of maceration  
in 200 ml methanol, Rumidatul et al. extracted  
145.21 mg GAE/g TPC and 95.39 mg QE/g TFC  
from a 50 g twig of Falcataria moluccana Miq [34].  
Teinkela et al. produced 236.3 g of total crude  
extracts by extracting 1.3 kg of the root bark and  
3.4 kg of the root wood from Piptadeniastrum  
africanum (hook.f.) Brennan [35]. Thakur et al.

objectives and practical considerations, as  
summarized in Table 1.  
Maceration  
Sunday et al. subjected the leaves, seeds, and  
roots of Abrus precatorius Linn. to an agitated  
maceration in 1 L of sterile distilled water at 25 oC  
for 8 h [37]. The leaf, seed, and root extracts all  
had higher concentrations of tannins, phenols,  
and saponins than the root extracts. On the other  
Maceration is a traditional method of bioactive  
compound extraction from plant materials. The  
process involves crushing or grinding previously  
dried plant materials to fine particles and powder  
and dissolving the plant material in a polar or  
non-polar solvent. The maceration extraction  
process usually takes a long time, spanning  
hours, days, or weeks. The steps to conducting a

[39] a traditional medicinal plant used by the  
Bentian people of East Kalimantan, Indonesia to  
treat diabetes and fever showed that root  
extracts macerated in n-hexane, ethanol, and  
ethyl acetate for 48 h obtained extract yields of  
0.36 g, 0.52 g and 0.53 respectively. Calpurnia  
aurea (Ait.) Benth, a plant used by some  
communities in Ethiopia to treat wounds, was  
confirmed by Ayal et al. to possess wound healing  
and anti-inflammation properties [40]. The  
wound healing leaves extracts of Calpurnia aurea  
(Ait.) Benth was obtained in 5 L methanol (80%)  
after 48 h. Belayneh and Birru [41] also extracted

barks of A. mangium and P. falcataria wood tree  
species found in Indonesia in dichloromethane,

[46]. They reported total extract yields of 17.81%  
from A. mangium and 6.65% from P. falcataria.  
Tamarindus indica is a hardwood tropical tree  
widely distributed in some parts of Africa and

roots and bark extracts of T. indica collected in  
Ghana have anti-inflammatory and antioxidant  
properties [48]. Soxhlet extraction afforded  
10.4% root extract yield and 8.1% bark extract  
yield. The root extracts of T. indica L. from India

hours [43]. Gupta and Patel revealed flavonoids,  
terpenoids, and steroids in seed methanol  
extracts of Mucuna pruriens after maceration of  
100 g of sample in 450 mL of 95% methanol for  
48 h [44].  
According to estimates, 463 million people had  
diabetes in 2019. By 2030, that number will climb  
to 578 million and by 2045, it will reach 700  
million [50]. Diabetes mellitus elevates blood  
sugar levels due to metabolic disruptions of  
macromolecules like protein and carbohydrates.  
Yusro et al. investigated the methanol bark  
extracts of Parkia intermedia, Parkia speciosa, and  
Parkia timoriana for α-glucosidase inhibition [51].  
These plants were investigated for scientific  
proof of their efficacy in traditional antidiabetic  
treatments in West Kalimantan Province,  
Indonesia. Roots (30 g) were extracted in 100 ml  
Soxhlet Extraction  
Soxhlet  
extraction  
is  
a
non-conventional  
technique for bioactive molecule extraction from  
plants. The technique has been used since 1879  
when German chemist Franz von Soxhlet first  
proposed it for lipids extraction [19]. Soxhlet  
apparatus consists of a thimble, an extractor, a  
round-bottomed flask, a siphon, and a condenser  
[45]. Extraction is carried out when a solid sample  
material in the thimble is run over by an  
extracting solvent heated from the round-  
bottom flask. The solvent with potential  
extractives from the sample material is  
repeatedly siphoned into the round-bottomed  
flask. This process is allowed to run under reflux  
for the duration of the extraction.

Cassia fistula stem bark extracted in ethanol by a  
soxhlet method by Agnihotri and Singh also  
showed antidiabetic effects and antioxidant  
properties by lowering blood glucose and  
preventing renal complications associated with  
hyperglycemia in their study [52].

Extraction Assisted by Microwave  
One of four more recent energy-dependent  
technologies used to extract bioactive chemicals  
from plants is microwave-assisted extraction  
(MAE). MAE uses microwave radiation to heat  
plant materials and transfer components into an  
extraction solvent [59]. Several factors contribute  
to the efficiency of MAE: solvent nature, solute-

and  
microwave irradiation power [60]. Microwave  
extraction lowers extraction time and solvent  
consumption and increases the quality of extract  
yield [61]. It is considered a green method due to  
the small organic solvent used for extraction.  
The total saponins (TSC) and total phenolic  
content (TPC) of fenugreek (Trigonella foenum-  
graecum L.) seed powder was identified by MAE  
by Akbari et al [62]. After 3 mins, 195.32 mg/g and  
81.55 mg/g yields were recorded in 80% ethanol  
at 70 oC and 600 W. The best solute-solvent ratio  
was 1:10 g/mL from a tested range of 1:8 to 1:12  
g/mL. Solarte et al. found that 32.5 min was the  
optimal time to extract 34.8 mg/g inositol from  
the leaves of M. sativa L. (Alfalfa) [63]. Mocan et al.  
extracted three isoflavones (puerarin, daidzein,  
and genistein) from the dried roots of P. lobate  
[64]. After 30 min, 10.9 µg/mg puerarin, 1.30  
µg/mg daidzein, and 0.12 µg/mg genistein extract  
yields were achieved at 40oC.  
The Global Initiative for Asthma Report 2021  
estimates that 1-18% of the global population are  
asthmatic [55]. Asthma is a lung disease caused  
by inflammations of the airway to the lungs. It  
results in tightness in the chest, which leads to  
breathing difficulties. Taur et al. extracted 500 g  
of leaf samples of A. precatorius Linn in 95%  
ethanol [56]. The leaf extracts exhibited  
antibacterial, anticancer, anti-diarrheal, and anti-  
asthma activities. Govindarajan et al. extracted  
1000 g of D. elata (L.) leaves and seeds to research  
plant-based insect-repellant chemicals. They  
then diluted the sample with 5000 mL of hexane,  
ethyl  
acetate,  
benzene,  
chloroform,  
and  
methanol [57]. For every leaf and seed sample  
gram, they reported the highest yields (149.20  
and 128.02) in methanol and lower yields (92.85  
and 86.38 yields) in hexane, respectively. The  
other extract yields were 108.30 per-gram leaf  
and 100.20 per gram seed (benzene), 116.42 per  
Mangang et al. studied different solvent natures  
(60-100%) for bioflavonoid extraction from the  
barks of A. myriophylla [65]. An optimum 156.81  
mg/g yield was obtained in 70.36% ethanol.  
Zuluaga et al. tested inositol extraction from seed  
and pod of Glycine max (L.) Merr (Soybeans) by  
microwave in 0-100% ethanol concentrations  
[66]. High inositol yields of 28.51 mg/g and 50.97  
mg/g were achieved in 0% ethanol at 120 oC after  
16.5 min. Vila Verde et al. isolated caryophyllene

(C22H22O11), vicenin-3 (C26H28O14), and vicenin-2  
(C27H30O15) were also present in the extract, as  
confirmed by HREI-MS. Condensed tannins like  
proanthocyanidins and polyphenols such as  
robinetinidol, fisetinidol, and gallocatechin were  
isolated from ethanol bark extracts of Acacia  
mangium by Chen et al [76] Rosdiana et al [46]  
found high amounts of fatty acids such as  
palmitic acid in bark DCM extract of Acacia

a
spectroscopic elucidation (HR-TOF) confirmed  
the molecular formula of 2-arylbenzofuran to be  
C17H14O6 (m/z 315.08765, [M+H] +). 1H NMR  
further confirmed that a chemical shift at 10.05  
ppm for an aldehyde proton and two shifts at  
7.10 ppm showed the presence of aromatic  
protons. Methyl carbons, aromatic ring carbons  
(Sp2  
hybridized),  
oxygenated  
and  
non-  
oxygenated quaternary carbons, and carbonyl  
carbon were all identified from the 13C NMR  
spectra. In addition to some previously reported  
compounds like 3, 5, 7, 3′, 4′, and 5′-  
hexahydroxyflavone (flavonoid), quercetin-3-O-  
galactopyranoside (flavonoid), and myricetin-3-  
O-galactopyranoside (flavonoid), Ahmed et al.  
isolated what they called novel bioactive  
compounds, including 24-isopropylcholest-5-en-

rha-glu-rha-glu [77,78]. Twenty (20) compounds  
were isolated from twig methanol extract of  
Falcataria moluccana by Rumidatul et al [34]. In  
the extract's GC-MS analysis, the following

Flavonoids and polyphenolics are relatively  
prevalent secondary metabolite chemicals in  
plants of the Fabaceae family based on our  
thorough evaluation of the literature (Table 2).  
However, the leaves, roots, and stems of  
Fabaceae plants could also contain considerable  
levels of quinones, steroids, terpenoids, and  
alkaloids. Flavonoids like quercetin (Figure 3(10))  
and myricetin (Figure 3(2)) and their derivatives  
such as quercetin-3-O-glucoside shown in Figure  
3(3) and myricetin-3-O-glucoside shown in Figure  
3(4) were found in several body parts of Fabaceae  
limonene,  
trimethyl-,  
Bicyclo[4.1.0]  
and  
hept-2-ene,  
Delta 3-Carene.

King et al. found guaiacol and 1-hydroxy-3-

anthraquinone  
in the aqueous and methanol extracts, chondrila  
sterol and stigmast-7-en-3-ol in the n-hexane  
extract, ethyl iso-allocholate and ergosta-5,22-  
dien-3-ol in the methanol extract of Albizia  
falcataria [79]. By using HRESIMS, 1D, and 2D  
NMR, Fotso et al. identified several compounds in  
Albizia glaberrima extracts, including (+)-(2R, 3S,

Erythrina abyssinica Lam. Ex.DC. is found in some  
tropical parts of Africa. (+)-Erysodine (alkaloid),  
Licoagrochalcone A (chalcone), and Indicanine B  
(coumarin) have been profiled in the seed, twig,  
and root bark extracts of E. abyssinica [90] With  
MIC values of 104 g/mL and 5 g/mL, stem bark  
DCM extract of E. lysistemon exhibited good  
antibacterial activity against S. aureus and S.  
epidermidis, according to Sadgrove et al [91], the  
DCM extract of E. lysistemon contained isoflavone  
derivatives such as Erybraedin A, phaseollidin,  
researchers have been investigating the bioactive  
efficacy of plant-based extracts for this purpose.  
Antibacterial Activity  
Acacia ligulata, an Australian traditional medicine  
plant used for treating chest infections, was  
found to have antibacterial action, according to  
Jæger et al [84]. With MIC values of 1000 g/mL for  
S. epidermidis and S. aureus and 62.5 g/mL for S.  
pyogenes, the ethanol bark extract proved  
effective against these bacteria. The bark, leaves,  
and seeds of C. ferrea C. Mart. are used in  
Brazilian traditional medicine for tea, concoction,  
and infusion in treating respiratory conditions  
[85]. By microdilution, Luna et al.'s study of  
chloroform leaf extract of C. ferrea revealed  
activity against S. aureus and B. subtilis at MIC  
values of 0.78 mg/mL [86]. they also stated that  
terpenes and flavonoids were detected in the  
extract. Using an agar well diffusion method with  
a MIC of 1.95 mg/mL, Belay et al. demonstrated  
the effectiveness of Calpurnia aurea's ethyl  
acetate, n-hexane, and DCM leaf extracts against  
S. typhi [87] For the ethyl acetate stem bark  
fraction of Macrolobium latifolium Vogel, Ferraz et  
al [88] demonstrated better antibacterial activity  
against S. aureus, S. epidermidis, K. pneumoniae,  
and P. mirabilis with MIC of 250 mg/mL, 50

Finally, Heydari et al. (2019) [92] demonstrated in  
a broth dilution test against B. subtilis and E. coli  
that the ethyl acetate aerial component extracts  
of five species of Lathyrus L., including armenus,  
aureus, cilicicus Karaman, laxiflorus subsp.  
Laxiflorus,  
and  
pratensis,  
exhibit  
some  
antibacterial activity [92]. When do Nascimento et  
al. tested an ethanol flower extract of S.  
macranthera for antibacterial activity, they  
discovered modest activity against P. gingivalis at  
MIC values of 400 g/mL [93]. The ethyl acetate  
fraction of S. macranthera was used to identify  
flavones (gallocatechin) and proanthocyanidins  
(guibourtinidol-gallocatechin).

The phenolic content of the stem bark methanol  
extract of C. cajan (L.) Millsp and antioxidant  
activity were found to be correlated, according to  
Sinan et al. [95]. The extract's significant  
antioxidant activity was detected by a DPPH  
radical scavenging experiment, which was 38.41  
0.05 mg TE/g. According to Khan et al., the ethyl  
acetate extract of C. ambigua's strong radical  
scavenging activity (83.32 6.22 mgTE/g) in the  
DPPH assay was caused by the extract's high  
phenolic (85.87 2.96 mg GAE/g) and flavonoid  
contents (66.45 0.37 mg RE/g) contents [96]. Ali et  
al. also confirmed high phenolic and flavonoid  
contents in C. brachyantha Rech. F [97]. A  
relationship was established between TPC and  
TFC with antioxidant activity because the ethyl  
acetate extract assayed by DPPH showed  
antioxidant activity of 77.91±4.96 mgTE/g. The  
TPC and TFC of the methanol leaves extract of S.  
auriculata (L.) Roxb., which had an IC50 of 76.24  
mg/mL, may have also contributed to the  
extract's ability to scavenge free radicals,

Similar

were

A. scabrifolium. An antioxidant potential of 27.30  
± 0.56 mg TE/g was reported.  
Conclusion  
The Fabaceae family comprises species of  
considerable  
ecological  
and  
economic  
significance. In addition to providing food,  
medicine, and shelter, many Fabaceae trees  
serve as vital sources of economic value through  
their roles as food crops, dye sources, forage and  
fodder plants, ornamentals, and timber-yielding  
species. This review highlights both conventional  
extraction methodssuch as maceration and  
Soxhlet extractionand advanced, technology-  
driven techniques, including microwave-assisted  
extraction, employed in the recovery of  
secondary metabolites from Fabaceae plants. We  
summarize extract yields obtained from various  
plant parts (leaves, roots, bark, stems, and pods),  
taking into account the influence of solvent  
polarity, extraction duration, and temperature.  
The review also identifies key secondary  
metabolites isolated from different plant organs,  
with flavonoids and polyphenolic compounds  
emerging as the predominant constituents.  
Notably, flavonoids such as quercetin, myricetin,  
and their glycosylated derivatives (e.g., quercetin-  
3-O-glucoside and myricetin-3-O-glucoside) are  
according  
to  
Parasathkumar  
et  
al  
[98].  
Indrianingsih et al. agreed with Sinan et al [95]  
and Ali et al [97] by suggesting low phenolic  
content in the methanol flower extract of C.  
ternatea was responsible for the poor radical  
scavenging activity of the extract by showing IC50  
of 800 μg/mL [99].  
Haidara and Al-Oqail [100] indicated that rutin  
and quercetin ethyl acetate fraction of C. italica  
exhibited about 100% antioxidant capacity in  
DPPH. According to Kurt-Celep et al [101], rutin  
from the methanol aerial portions of A.  
campylosema has antioxidant activity ranging  
from 47.13 to 48.10 mg TE/g. Enyl-2,2'-

P. Seven underutilized species of the Fabaceae  
family with high potential for industrial  
application as alternative sources of oil and  
lipophilic bioactive compounds. Industrial Crops  
commonly reported. Although isolating sufficient  
quantities of bioactive compounds from plant  
sources remains a challenge, the integration of  
natural product chemistry with synthetic drug  
development is increasingly recognized for its  
potential.  
Natural  
product-derived  
pharmaceuticals tend to be more widely  
accepted than synthetic counterparts due to  
their lower toxicity and higher therapeutic  
efficacy. Numerous studies have reported the  
antibacterial, antioxidant, and anti-inflammatory  
properties of Fabaceae extracts. This review  
compiles evidence of antibacterial activities  
against strains such as Klebsiella pneumoniae,
