Seven new serratene triterpenoids, 3α,21β,29-trihydroxy-16-oxoserrat-14-en-24-oic acid (1), 3β,21β,29-trihydroxy-16-oxoserrat-14-en-24-oic acid (2), 3β,21β,29-trihydroxyserrat-14-en-24-oic acid 3β-(4-hydroxybenzoate) (3), 3β,21β,29-trihydroxyserrat-14-en-24-oic acid 3β-(4-hydroxy-3-methoxybenzoate) (4), 3β,14α,15α,21β,29-pentahydroxyserrat-14-en-24-oic acid 3β-(4-hydroxybenzoate) (5), 3α,21β,24,29-tetrahydroxyserrat-14-en-16-one (6), 3α,21β,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.
