其中7个倍半萜內酯:11α

13-dihydrotomentosin (1)

sundiversifolide (2)

8-epi-xanthatin-1β

5β-epoxide (3)

ivaxillin (4)

13-dehydroivaxillin (5)

1β-hydroxyalantolactone (6)

carabrone (7); 4个三萜类化合物:taraxasterol 3-O-acetate (8)

maniladiol 3-O-palmitate (9)

16β-hydroxylupeol 3-O-tetradecanoate (10)

arnidiol (11)。结论 :所有化合物均为首次从该植物中分离得到。

Abstract

Objective: To investigate the chemical constituents of Inula helianthus-aquatica.Eleven compounds were isolated from the title plant. Method : These compounds were isolated by various chromatography methods such as silica gel

et al. Their structures were elucidated by spectral analysis like MS

NMR. Result : Seven sesquiterpene lactones were isolated and elucidated as 11α

13-dihydrotomentosin (1)

sundiversifolide (2)

8-epi-xanthatin-1β

5β-epoxide (3)

ivaxillin (4)

13-dehydroivaxillin (5)

1β-hydroxyalantolactone (6)

carabrone (7). Four triterpenes were isolated and elucidated as taraxasterol 3-O-acetate (8)

maniladiol 3-O-palmitate (9)

16β-hydroxylupeol 3-O-tetradecanoate (10)

arnidiol (11). Conclusion : All the compounds were isolated from I. helianthus-aquatica for the first time.
