Descripción
Sumario:Four new endiandric acid analogues, tsangibeilin C (1), tsangibeilin D (2), tricyclotsangibeilin (3) and endiandric acid M (4), one new lignan, beilschminol B (5) and two new sesquiterpenes, (+)-5-hydroxybarbatenal (6) and (4R,5R)-4,5-dihydroxycaryophyll-8(13)-ene (7), together with four known compounds (8–11), were isolated from the roots of Beilschmiedia tsangii (Lauraceae). The structures of 1–7 were determined by spectroscopic techniques. Among the isolates, endiandric acid M (4) exhibited moderate iNOS inhibitory activity, with an IC(50) value of 31.70 μM.
