Definition
Brucea macrocarpa is a species of flowering plant in the family Simaroubaceae. It is a tree or shrub native to parts of tropical Asia.
Overview
The species is recorded from several regions of Southeast Asia, including the Philippines, Malaysia, and Indonesia. It grows in lowland tropical forests, often on disturbed sites or secondary growth. Like other members of the genus Brucea, it produces compound leaves, small inconspicuous flowers, and fleshy fruit. The plant has been mentioned in ethnobotanical literature for its use in traditional medicine, although detailed pharmacological studies are limited.
Etymology / Origin
The generic name Brucea honors the 18th‑century Scottish explorer James Bruce, who is credited with introducing the plant to European botanists. The specific epithet macrocarpa derives from the Greek words makros (μακρός, “large”) and karpos (καρπός, “fruit”), referring to the comparatively large fruits of the species.
Characteristics
- Growth form: Evergreen tree or shrub, typically attaining heights of 5–15 m, though exact maximum size varies across its range.
- Leaves: Pinnately compound, glossy dark green, with several leaflets arranged oppositely along the rachis.
- Flowers: Small, yellowish‑green, arranged in panicles; the flowers are hermaphroditic and lack prominent petals.
- Fruit: Spherical to ovoid drupes, relatively large for the genus (hence macrocarpa), turning yellow to orange when ripe; each contains a single seed.
- Wood: The timber is soft and not widely used commercially.
- Chemical constituents: Preliminary phytochemical investigations have identified quassinoids and other limonoid compounds, which are characteristic of Simaroubaceae species and are investigated for antimalarial and anticancer activity. Accurate information on the full chemical profile is not confirmed.
