Aglaia elaeagnoidea is a shrub or small tree, up to 20 m. Leaves are compound, about 6-30 cm long, with 1-3 pairs of leaflets. Leaflet is leathery, elliptic to slightly obovate shaped, 5-12 cm long and 2-4.5 cm wide, with tapering or blunt tip and an asymmetric base.  Upper surface of leaflets is covered with pale orange-brown fringed scales. Scales also occurs at the petiole, leaf axis, calyx, inflorescences and young branches. Male inflorescence is 9-34 cm, longer compared to female inflorescence which is up to 12 cm long. Flower is about 3 mm diameter and comprises of 5 petals and 5 protruding anthers.

Studies
Cytotoxicity / Bark:
Study of bark isolated two new rocaglamides, 8b-O-5-oxohexylrocaglaol (1) and elaeagnin (2), together with 12 known compounds. Three rocaglamide derivatives, dehydroaglaiastatin (13), 8b-O-5-oxohexylrocaglaol (1) and rocaglaol (5) exhibited significant cytotoxic activity against HepG2 human liver cancer cells with IC50s of 0.69, 4.77 and 7.37 µM. respectively. (3)
Antioxidant / Antimicrobial / Leaf and Stem Bark: In vitro antioxidant activity of ethanolic extracts of leaf and bark exhibited maximum phenolic compounds and scavenging activity. Phenolic compounds of leaf and bark showed positive correlation to antioxidant activity. All crude extracts of leaf and bark showed low to moderate inhibition zones against Staphylococcus aureus, Bacillus subtilis, Escherichia coli, Vibrio vulnificus, and Candida albicans. Crude extracts of bark showed greater antioxidant and antimicrobial activity than leaf extracts. (5)
Silver and Gold Nanoparticles / Waste Water Treatment / Flowers: Study reports on the easy, rapid, non-toxic, energy-efficient, cost-effective synthesis of gold and silver nanoparticles using flower extract of Aglaia elaeagnoidea. Results suggest potential for application of biosynthesized Ag and AuNPs as nanocatalyst in waste water treatment. (6)
Silver and Gold Nanoparticles / Mosquito Nanolarvicides: Study reports on the Priyangu-mediated synthesis of Ag nanoparticles toxic to Culex quinquefasciatus, Aedes aegypti, and Anopheles stephensi. The plant extract and nanolarvicide were tested on the three mosquito vectors and on three non-target mosquito predators. Priyangu extract exhibited moderate toxicity while the Priyangu-synthesized AgNPs were highly toxic to Cx. quinquefasciatus (LC50 24.91, LC90 45.96 µg/mL), Ae. aegypti (LC50 22.80, LC90 43.23 µg/mL), and An. stephensi (LC50 20.66, LC90 39.94 µg/mL). The extract and AgNPs were found safer to non-target larvivorous fishes, backswimmers, and waterbugs, with LC50s ranging from 1247 to 37,254.45 µg/mL, if compared to target pests. (7)
Nutritional Value / Fruits: Fruits yield carbohydrates and terpenoid compounds. Wild edible fruits possess nutritional factors carbohydrates (57.10%), proteins (52.78%), and fat (0.08%), along with antioxidant property by DPPH assay. (see constituents above) (9)
Copper Oxide Nanoparticles / Catalytic / Flowers: Study reports on a phytogenic synthesis using flower extract for a highly active, recoverable, and recyclable heterogenous copper oxide nanocatalyst encapsulated within biomaterial that acts as a nontoxic and renewable source of reducing and stabilizing agent. The CuO NPs showed great potential in reduction of pernicious dyes and nitro organic pollutants in water. (10)
Lupeol / Antiasthmatic / Bronchodilating / Fruit Pulp: Study evaluated the bronchodilating effect of lupeol isolated from the fruit pulp of Aglaia elaeagnoidea using isolated goat trachea chain preparation. The lupeol isolated from fruit pulp of Aglaia elaeagnoidea inhibited the contractile effect of histamine (p<0.05) on histamine-induced contraction in isolated goat tracheal chain. (11)
Anticancer / Terpenoids / Stem Bark: Study of stem bark isolated five compounds, which were tested for cytotoxicity against HeLa cervical cancer and DU145 prostate cancer cells. Compound 4, 20S,24S-epoxydammarane-3α,25-diol, showed stronger activity compared to other compounds. (see constituents above) (12)
Wound Healing / Dead Space and Burn Wound / Ointment Formulation / Leaves: Study evaluated the wound healing potential of ethanolic extract ointment of Aglaia elaeagnoidea in dead space and burn wounds. Results showed significant healing (p<0.01) in all wound models. All parameters such as wound contraction showed significant (p<0.01) changes compared to control. (13)
