利用多种色谱分离方法对川西獐牙菜的化学成分进行研究,从其全草的乙醇提取物中分离得到四个化合物,应用HR-ESIMS,1D和2D NMR,IR,UV等多种现代波谱技术确定了这些化合物的化学结构,经鉴定分别为(S,2E,6E)-2,6-二甲基-4,8-二羟基辛烷-2,6-二烯酸(1),(S,2E,6E)-2,6-二甲基-4-羟基-8-甲酰氧基辛烷-2,6-二烯酸(2),swerimilegenins B和C(34).化合物12为两个新的链状单萜类化合物,分别命名为川西獐牙菜酸C和D,化合物34是两个不常见的C9骨架的环烯醚萜,为首次从该植物中分离得到.

Investigation on Swertia mussotii resulted in four compounds by means of various chromatographic techniques (silica gel, Sephadex LH-20, RP-LC and Pre-HPLC). Their structures were determined as (S,2E,6E)-4,8-dihydroxy-2,6-dime-thylocta-2,6-dienoic acid (1), (S,2E,6E)-8-(formyloxy)-4-hydroxy-2,6-dimethylocta-2,6-dienoic acid (2), swerimilegenins B and C (3 and 4) on the basis of extensive spectroscopic analyses including MS, IR, UV, 1D- and 2D-NMR. Among them, compounds 1 and 2 are two new linear monoterpenoids named as swerimusic acids C (1) and D (2), compounds 3 and 4 are two unusual known secoiridoid aglycones of C9-skeleton obtained for the first time from this plant. Compounds 1~4 were evaluated for their anti-Hepatitis B Virus (HBV) activities on HepG2.2.15 cells line in vitro, but these compounds showed no anti-HBV activity at the maximal tesing concentration. Herin, we only report the isolation and structure elucidation of these compounds.
