OBJECTIVE
To study the chemical constituents of Cynanchum forrestii.
METHOD
Chromatographic techniques were applied to isolated chemical constituents. The structures were identified on the basis of physico-chemical constants and spectroscopic data.
RESULT
Eight compounds were isolated from the 95% ethanol extract of the roots of C. forrestii and elucidated as ( + ) -5'-methoxyisolariciresinol 3a-O-beta-D-glucopyranoside (1), hexahydroxycholest-7-en-6-one (2), tylophorinidine (3), sucrose (4), palmitic acid (5), beta-sitosterol (6), daucosterol (7), nonanedioic acid (8).
CONCLUSION
Compounds 1-3 from this genus, and compounds 4-8 from the plant were obtained for the first time.
目的
研究大理白前的化学成分。
方法
采用色谱技术分离化学成分。根据理化常数和光谱数据鉴定结构。
结果
从大理白前根的95%乙醇提取物中分离得到8个化合物，分别鉴定为(+)-5'-甲氧基异落叶松脂醇3a-O-β-D-吡喃葡萄糖苷(1)、六羟基胆甾-7-烯-6-酮(2)、娃儿藤定碱(3)、蔗糖(4)、棕榈酸(5)、β-谷甾醇(6)、胡萝卜苷(7)、壬二酸(8)。
结论
化合物1 - 3为本属首次得到，化合物4 - 8为该植物首次得到。
