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.
从锡金垂穗石松（Palhinhaea cernua var. sikkimensis）中分离得到7个新的锯齿烷型三萜类化合物，分别为3α,21β,29-三羟基-16-氧代锯齿-14-烯-24-酸（1）、3β,21β,29-三羟基-16-氧代锯齿-14-烯-24-酸（2）、3β,21β,29-三羟基锯齿-14-烯-24-酸3β-(4-羟基苯甲酸酯)（3）、3β,21β,29-三羟基锯齿-14-烯-24-酸3β-(4-羟基-3-甲氧基苯甲酸酯)（4）、3β,14α,15α,21β,29-五羟基锯齿-14-烯-24-酸3β-(4-羟基苯甲酸酯)（5）、3α,21β,24,29-四羟基锯齿-14-烯-16-酮（6）、3α,21β,30-三羟基锯齿-14-烯-16-酮（7），同时还得到12个已知化合物（8 - 19）。通过光谱数据并与文献值比较对它们的化学结构进行了鉴定。
