title: Swartziarboreol diterpenes from Swartzia langsdorffii Raddi.
abstract: Two new swartziarboreol diterpenes (1 and 2) and swartziarboreol C were isolated from the petroleum ether extract of the roots of Swartzia langsdorffii. Their structures were elucidated by spectroscopic evidence. The biological activity of the root extracts and 2 was evaluated through bioautography and brine shrimp lethality assays.
