title: Serratene triterpenoids from Palhinhaea cernua var. sikkimensis.
abstract: Seven new serratene triterpenoids, 3alpha,21beta,29-trihydroxy-16-oxoserrat-14-en-24-oic acid (1), 3beta,21beta,29-trihydroxy-16-oxoserrat-14-en-24-oic acid (2), 3beta,21beta,29-trihydroxyserrat-14-en-24-oic acid 3beta-(4-hydroxybenzoate) (3), 3beta,21beta,29-trihydroxyserrat-14-en-24-oic acid 3beta-(4-hydroxy-3-methoxybenzoate) (4), 3beta,14alpha,15alpha,21beta,29-pentahydroxyserrat-14-en-24-oic acid 3beta-(4-hydroxybenzoate) (5), 3alpha,21beta,24,29-tetrahydroxyserrat-14-en-16-one (6), 3alpha,21beta,30-trihydroxyserrat-14-en-16-one (7) were isolated from Palhinhaea cernua var. sikkimensis, together with twelve known compounds (8-19). Their chemical structures were elucidated on the basis of spectroscopic evidence and comparison with literature values.
