About

Gmelina arborea, (in English beechwood, gmelina, goomar teak, Kashmir tree, Malay beechwood, white teak, yamane ), locally known as gamhar, is a fast-growing deciduous tree in the family Lamiaceae.

Safety

Lignans, such as 6" - bromo - isoarboreol, 4-hydroxysesamin, 4,8-dihydroxysesamin, 1,4-dihydroxysesamin (gummadiol), 2-piperonyl-3-hydroxymethyl-4-(α-hydroxy-3,4-methylenedioxybenzyl)-4-hydroxytetrahydrofuran and the 4-O-glucoside of 4-epigummadiol, can be isolated from the heartwood of Gmelina arborea. The parent compounds are arboreol or gmelanone.

Umbelliferone 7-apiosylglucoside can be isolated from the root.

Where it grows

Gmelina arborea grows naturally throughout India, Myanmar, Thailand, Laos, Cambodia, Vietnam and in southern provinces of China. It is found at altitudes from sea level to 1,500 metres (5,000 ft). Since the 1960s, it has been introduced extensively as fast-growing timber trees in Brazil, Gambia, Honduras, Ivory Coast, Malaysia, Malawi, Nigeria, the Philippines, and Sierra Leone.
