[摘要] 对菊科蚂蚱腿子属植物万花木Myripnois dioica地上部分的化学成分进行研究。利用多种色谱技术从万花木95%乙醇提取物中分离得到12个化合物;通过理化性质和波谱数据分别鉴定为8-desoxyurospermal A(1),zaluzanin C(2),dehydrozaluzanin C(3),glucozaluzanin C(4),macrocliniside B(5),macrocliniside I(6),taraxinic acid-14-O-β-D-glucopyranoside(7),ainsliaside B(8),洋芹素(9),木犀草素(10),洋芹素-7-O-β-D-吡喃葡萄糖苷(11)和木犀草素-7-O-β-D-吡喃葡萄糖苷(12)。除化合物8以外,其他化合物均为首次从该属植物中分离得到。对化合物8的降血糖活性进行了研究,结果表明化合物8可较好地降低四氧嘧啶所致糖尿病小鼠的血糖水平。

[Abstract] To study the chemical constituents of the aerial parts of Myripnois dioica. Twelve compounds were separated from the 95% ethanol extract of M. dioica by using various chromatographic techniques. Their stuctures were identified on the basis of their physicochemical properties and spectral data as 8-desoxyurospermal A(1) ...... 第 1 2 3 4 5 页 下一页
