不同溶剂所制何首乌浸膏中所含游离蒽醌的含量比较

A comparion of free anthraquinone's content of polygonum multiflorm extract by different dissolvent produced

目的 观察不同溶剂所制何首乌浸膏中所含游离蒽醌的含量变化。方法 以醋酸镁显色 ,用 75 4分光光度计在波长 498nm处测定A值 ,从而求得游离蒽醌的含量。结果 A组 ( 90 %乙醇 )平均游离蒽醌的含量为 0 .14 95 %,B组 ( 70 %乙醇 )为 0 .0 673 %,C组 (水 )为 0 .0 0 84%,A组含量显著高于B组和C组 (P <0 .0 5 )。

Objective To observe the content's changes of free Anthraquinone in polygonum multiflorum extract produced by different dissolvent.Methods The content of free anthraquinone was determined by the magnesiujm Acetate colorinetry in 754-spectrophotometer at 498nm,after determining A.Results The average content of free anthraquinone was 0.1459in group A(90% Alcohol),0.0673 in groupB(70%Alcohol)and 0.0084 in group C(water).The content in group A is higher significantly than that in GroupB and in groud C(P<0.05).Conclusions Among three schemes.A can be used to extract the free anthraquinone of ploygonun Multiflorum extract first.
