New antimycobacterial triterpenoids from Rhus taitensis.

Two new triterpenoids were isolated from the leaves and twigs of Rhus taitensis. Their structures were elucidated by 1D and 2D NMR spectroscopic studies as 1,10,24,25,30-pentahydroxysqualene and dammar-20(22),24-diene-3 β,26,27-triol. Both compounds exhibited moderate antimycobacterial activities with an MIC of 45 µg/mL.
