“…Several phenolic and flavonoid constituents including caffeic acid, isorhamnetin-3-O-galactoside, isorhamnetin, kaempferol-3-Orubinoside, chrysoeriol, quercetin-3-O-rhamnoside, and luteolin-7-glucoside were isolated and identified from solvent fractions of aerial parts aqueous-alcoholic extract of L. leucocephala [35]. Quercetin was isolated from the ethyl acetate fraction obtained from leaf crude ME [36]. By HPLC, quercetin, caffeic acid, and scopoletin in proportions of 82.21%, 13.42%, and 4.37%, respectively, were identified in Leucaena leucocephala leaves [48].…”

“…Mimosine, gallic acid, caffeic acid, β-sitosterol, luteolin-7-O-glucoside, chrysoenol, and kaempferol-3-O-rutinoside were identified in the extract [35]. Extracts from different parts of the tree showed the presence of several bioactive compounds such as quercetin from leaf extract [36]. The whole plant showed the presence of several compounds such as polyprenol, lupeol, squalene, and β-sitostenone [21].…”

The biomass production from Leucaena leucocephala (Lam.) de Wit (family Fabaceae) is a valuable source for chemical biorefinery. The bioactive molecules from the methanol extracts (MEs) from various parts of L. leucocephala grown in Egypt were evaluated. The antibacterial activity against the growth of Erwinia amylovora, Agrobacterium tumefaciens, and Staphylococcus aureus was determined by the inhibition zones (IZs) and the minimum inhibitory concentrations (MICs). The antifungal activity against the growth of Rhizoctonia solani, Fusarium solani, and Alternaria solani was recorded by measuring the fungal growth inhibition (FGI %) and MICs. The phytochemical compounds in the MEs were identified by HPLC–DAD, where the higher compounds identified (mg/kg ME) in seeds were benzoic acid (1520.44), myricetin (848.73), and rosmarinic acid (792.46); in roots, were benzoic acid (554.04), naringenin (419.99), and myricetin (205.51); in leaves were rosmarinic acid (4768.16), resveratrol (2983.99), quercetin (2052.43), myricetin (1432.63), and naringenin (1182.39); in branches, were rosmarinic acid (2230.26), resveratrol (1605.3), o-coumaric acid (691.16), and myricetin (681.93); in fruits were rosmarinic acid (431.43) and resveratrol (261.07); in stem-wood, were ellagic acid (1319.75), p-coumaric acid (1051.59), and ferulic acid (512.45); and in stem-bark, were resveratrol (1079.01), benzoic acid (1071.11), and catechol (305.51). The MEs at the concentration of 4000 mg/L from stem-wood, leaves, and stem-bark, the higher IZs against the growth of E. amylovora, A. tumefaciens, and S. aureus with values of 4.06 cm, 2.5 cm, and 2.63 cm, respectively, were found. The range of MICs values of MEs was 75–500 mg/L, 75–125 mg/L, and 75–125 mg/L, against the growth of A. tumefaciens, E. amylovora, and S. aureus, respectively. MEs prepared from seeds, fruits (pod), and stem-bark at 4000 mg/L showed the higher FGI (100%) against the growth of A. solani; MEs from seeds and branches observed the higher FGI values of 63.83% and 63.6%, respectively, against the growth of F. solani, and all MEs showed potent antifungal activity (FGI 100%) against R. solani except for leaf ME (88.06%). MICs were in the range of 250–500, 250–500, and 500–1000 mg/L against A. solani, F. solani, and R. solani, respectively. At 500 mg/L, the roots ME showed the highest total antioxidant activity (94.30%) compared to vitamin C (VC) (98.30%) at 100 mg/L. The EC50 values of the MEs from seeds, fruits, stem-bark, branches, stem-wood, leaves, and roots were 424.24 mg/L, 131.40 mg/L, 341.78 mg/L, 380.50 mg/L, 153.59 mg/L, 153.59 mg/L, and 129.89 mg/L compared with VC (6.88 mg/L). In conclusion, the botanical parts of L. leucocephala have several bioactive compounds, which can act as promising antimicrobial and antioxidant properties.

“…Crude extract of L. leucocephala can suppress nematode populations on the soil and roots of tomato plants [67]. The aqueous extracts of the leaves and roots of L. leucocephala were reported to have nematicidal effects [68]. The myosin content (mimosine) in the roots, stems, leaves, and seeds of L. leucocephala can function as an allelopathic compound that exhibits fungicidal, insecticidal, and herbicidal activities so that it can be used as an active ingredient in fungicides, insecticides, and vegetable herbicides.…”

Shallot is one of the most important vegetables for Indonesian people due to its circumstances as the main ingredient in many Indonesian foods. The use of organic materials as nutrient sources is growing, concerning the increasing consumer demands on organic products and environmental issues such as climate change. Using organic materials helps plants to mitigate and adapt the environmental changes. This review described the potential organic sources as liquid organic fertilizer to support shallot growth. The method of this review was a systematic literature review that was grouped by themes. Liquid organic fertilizer is one of the most effective ways to improve plant production. The results showed that the effect of liquid organic fertilizer depends on the raw materials that were used. Several organic materials that potentially enhance shallot production and quality would be discussed, including rabbit manure, black soldier fly manure (kasgot) and white lead tree leaves. Those organic materials contain a high concentration of phosphorus, potassium and nitrogen that might accelerate shallot growth. The potential effect of those organic materials on increasing shallot production would be described briefly.
