Rhubarb contains toxic Oxalates and anthraquinone glycoside. 大黄含有毒草酸以及蒽醌苷。
Objective: To study the influence of temperature and alcohol concentration on extraction efficiency on extraction anthraquinone glycoside from polygonum cuspidate. 目的:研究提取温度和提取液乙醇浓度对从虎杖中提取蒽醌苷的影响。
Objective: To study the effect of anthraquinone glycoside from Polygonum multiflorum Thunb. ( AGPMT) in vitro on cellular immunological function in mice. 目的:研究何首乌蒽醌苷(AGPMT)体外对小鼠细胞免疫功能的影响。
Methods Hydrolyze the anthraquinone glycoside first and then separate them by PH gradient extraction, and purify emodin by chromatography at last. 方法先水解蒽醌苷,然后用pH梯度萃取法分离,最后柱层析法。
