Gen info
- Aglaia is genus of 117 species of woody dioecious trees belong to the Mahogany family Meliaceae.
- Due to considerable morphological variation, the genus is burdened with taxonomic problems, with the number of accepted species varying from 117 to over 390 depending on the species concept used. (3)

Botany
Aglaia tomentosa is small, sometimes medium-sized tree up to 15(-23) m tall, bole branchless for up to 9 m, up to at least 20 cm in diameter, bark surface pale reddish-brown or gray with green patches, inner bark yellow. Leaflets 5-11(-13), opposite or subopposite, with 5-25 pairs of secondary veins, above smooth and glabrous or the midrib densely covered with reddish-brown or orange-brown stellate hairs, below with numerous stellate hairs and interspersed with smaller paler hairs. Flowers 5-merous, anthers 5, style-head subglobose, longitudinally ridged. Fruit a subglobose indehiscent berry, 1-2-locular, ca. 2 cm in diameter, red, velvety, juicy. (1)

Distribution
- Native to the Philippines.
- Also native to Borneo, India, Jawa, Laos, Lesser Sunda Is., Malaya, Sulawesi, Sumatera, Thailand, Vietnam. (2)
- An understorey tree in evergreen, primary, secondary, riverine, montane, and ridge forests; from sea level to 2,000 m. (6)

Constituents
- Study of stem bark extract showed TPC of 6.11 mg GAE/g extract and TFC of 5.16 mg QE/g extract; DPPH radical scavenging activity IC50 of 31.04 ppm, and ABTS radical scavenging activity IC50 of 71.07 ppm. (see study below) (4)
- Study of bark isolated dammarane triterpenes, viz., the known cabraleone, cabraleadiol 3-acetate, 3-epiocotillol, cabralealactone, cabralealactone 3-acetate and the new aglinins C and D; along with two new pregnane steroids, aglatomins A and B, with known cytotoxic cyclopenttetrahydrobennzofuran, rocaglol. (see study below)   (5)

Properties
- Studies have suggested antioxidant and cytotoxicity properties.

Uses
Edibility
- Fruits are edible, although lacking in flavor. The acidic tasting, gelatinous, translucent covering (aril) around the seed is eaten, (6)
Folkloric
- No reported folkloric medicinal use in the Philippines.
Others
- Wood: Sapwood is pale brown or pinkish brown. Wood is not durable; density of 800-905 kg/m3 at 15% moisture. Used in construction, but not very durable when exposed. (1)

Studies
• Antioxidant / Cytotoxicity: Study evaluated 11 potential extracts from various Meliaceae plants family for antioxidant activity and cytotoxicity. Aglaia tomentosa showed highest antioxidant activity by ABTS assay with IC50 of 8.91 µg/mL. Antioxidant activity via DPPH radicals showed 29.32% inhibition. On cytotoxic activity testing on MCF7 cell line, A. tomentosa showed 80.40% inhibition at concentration of 100 ppm. (see constituents above) (4)
• Dammarane Triterpenoids and Pregnane Steroids / Cytotoxicity / Bark: Study of ethanol extract of bark showed cytotoxicity against KB cells (69% inhibition at 10 µg/ml). (see constituents above) (5)

Availability
Wild-crafted.
