Abstract Antifungal activity of constituents from the heartwood of the Malaysian Gmelina arborea against Trametes versicolor and Fomitopsis palustris was investigated. A sensitive bioassay system for antifungal activity against basidiomycetes was developed which uses a medium in which homogenized hyphae were dispersed. Ethyl acetate- solubles from the heartwood showed the highest activity against both fungi, although the activity against F. palustris was quite weak. Spots exhibiting antifungal…

TLDR
The stereochemistry of paulownin, isopaulown in, m.p. 132°, d-sesamin and d- asarinin were elucidated as IIa, IIb, Ia and Ib by the analysis of their NMR spectra, respectively and consequently, epi-asarinin as Ic.
Native species: a resource for the diversification of forestry production in the lowland humid tropics
TLDR
The native potential plantation species appeared to be well adapted to the low input forestry practiced by farmers in the lowland humid tropics, while the traditional forestry species probably require more intensive production systems.
