Four new steroidal glycosides, named capsicosides A-D together with proto-degalactotigonin, were isolated from the roots and seeds of Capsicum annuum var. conoides and Capsicum annuum var. fasciculatum. On the basis of detailed chemical and spectroscopic evidence, the structures of capsicosides A-D were shown to be furostanol glycosides corresponding to gitogenin and tigogenin oligoglycosides. Capsicoside A was regarded as the same compound as the previously described capsicoside, whose structure now needs to be revised according to the data presented in this report.
从圆锥辣椒和簇生辣椒的根和种子中分离出四种新的甾体苷，分别命名为辣椒苷A-D以及原去半乳糖替告皂苷元。基于详细的化学和光谱证据，辣椒苷A-D的结构被证明是与吉托皂苷元和替告皂苷元寡糖苷相对应的呋甾烷醇苷。辣椒苷A被认为与先前描述的辣椒苷是同一化合物，根据本报告提供的数据，其结构现在需要修订。
