猫爪草中化学成分的研究(英文)

Chemical Constituents of Roots of Ranunculus ternatus Thunb.

目的研究猫爪草中的化学成分。方法用各种色谱方法分离猫爪草中的化学成分,用理化常数和波谱技术对分离的化合物进行结构鉴定。结果从猫爪草块根中分离得到8个化合物,结构分别确定为棕榈酸(1),β-谷甾醇(2),γ-酮-δ-戊内酯(3),尿苷(4),5-羟甲基-糠醛(5),3,4-二羟基苯醛(6),呋喃果糖(7),β-谷甾醇-β-D-葡萄糖苷(8)。结论化合物(4),(5),(6)为从该植物中首次分离得到。

Ranunculus ternatus is culus, which is distributed a species of genus Ranunmainly in Henan, Hubei, Guangxi, Sichuan, and Yunnan provinces in China. The root of Ranunculus ternatus has been used for the treatment of faucitis, tuberculosis, neck scrofula, etc in traditional Chinese medicine.
