Six previously undescribed cycloartane triterpenes glycosides, cimimanols A–F (1–6), together with thirteen known analogues (7–19) were isolated from the rhizomes of Cimicifuga foetida. Among them, cimimanol A (1) was the first example of cycloartane triterpene glycoside featuring a unique cyclic carbonate, and cimimanol B (2) was a rare trinortriterpene glycoside. The chemical structures and absolute
六个以前未描述环阿屯烷三萜甙,cimimanols A-F(1 - 6),加上13个已知类似物(7 - 19)从根茎分离升麻。其中,cimimanol A(1)是具有独特环状碳酸酯的环戊烷三萜糖苷和cimimanol B(2)的第一个实例。)是一种罕见的三降三萜糖苷。在全面的光谱分析,化学方法,X射线晶体衍射以及量子化学计算的基础上,确定了新化合物的化学结构和绝对构型。最后,评估所有这些化合物对3T3-L1脂肪细胞的降脂作用。化合物1 - 3,6 - 10,12 - 16,18 - 19可以显著降低3T3-L1脂肪细胞的脂肪蓄积,特别是化合物8,9,14,和15 在10μM的浓度下具有很强的降脂作用,抑制率范围为8.35%至12.07%。
