Three new bisdesmosidic triterpenoid saponins, helianthoside 1(1), 2(2), and 3(3), were isolated from the flowers of Helianthus annuus L. and a new monodesmoside 4 was isolated after the cleavage of the ester-glycosidic linkages of 2 and 3. The structures of the compounds were elucidated by 13C-NMR, FAB-MS, GC/EI-MS of partially methylated alditol acetates and degradation methods.
从向日葵（Helianthus annuus L.）的花朵中分离出三种新的双糖链三萜皂苷，即向日葵苷1(1)、2(2)和3(3)，并且在2和3的酯糖苷键断裂后分离出一种新的单糖链皂苷4。通过¹³C-NMR、FAB-MS、部分甲基化糖醇乙酸酯的GC/EI-MS以及降解方法对这些化合物的结构进行了阐明。
