两种纯化工艺对大黄水提液中蒽醌类成分的影响研究
Influences of Two Purification Processe on Anthraquinones in Aqueous Extract Solution of Rheum palmatum
摘要
Abstract
Objective To explore the effect laws of chitosan flocculation clarification and alcohol precipitation process on the anthraquinones in aqueous extract solution of Rheum palmatum. Methods The retention rates of five anthraquinones in Rheum palmatum are as evalution indexes, the influences of two purification processes under the different conditions on the anthraquinones were investigated. Results Under the different conditions of two purification processes, the retention rates of five anthraquinones in aqueous extract solution of Rheum palmatum almost had the same laws: rhein > aloe emodin > emodin >chrysophanol >emodin methyl ether. Comparing two purification processes, the retention rates of alcohol precipitation process on anthraquinones were superior to ones of chitosan flocculation clarification process. Conclution The retention rates of low polarity constituents by alcohol precipitation were better than the chitosan flocculation clarification process, while the high polarity constituents were opposite.关键词
