四块瓦化学成份的研究(Ⅱ)

Studies on the Chemical Constituents of the Chloranthvs Holostegius(Hand-Mazz.)Pei et.Shan

四块瓦(Chloranthus Holostegius)为金粟兰科多年生草本植物,分布于云南、广西和贵州等地。全草有毒,具有抗菌、消炎、散瘀活血的功效。对四块瓦化学成份的研究尚未见报道,作者从其根的石油醚、乙醚和乙醇的提取液中,分离得到五个结晶单体。

Five crystalline substances have been obtained for the first time from the root of the chloranthus holostegius(Hand-Mazz.)Pei et.Shan,growing in Yuayang County of Yunnan Province.According to their spectroscopic analyses(UV,IR,MS,^(1)H and ^(13)CNMR)and physico-chemical constants,they have been identified as:β-Sitosterol(Ⅰ),β-Sitosteryl-β-D-glucoside(Ⅱ),Palmitic acid(Ⅲ),Fraxidin-8-O-β-D-glucoside(Ⅳ)and Chloranthalactone C(Ⅴ),respectively.
