Establishing a standard verification method for Five Flavors of Chinese medicine

Objective: To explore and establish experimental detecting method for the five flavours of traditional Chinese drugs.Methods: By the synchronic and blind method,ten trained experimental persons taste,grade and get the synthetic evaluation from ten decoction pieces(such as Huangbai,etc.),six Chinese herbal formula(like Huanglian Jiedu Decoction,etc.),and seven active Chinese herbal ingredients(like Berberine,etc.) Thus,studying and establishing detecting method for the five flavours of traditional Chinese drug.Results:(1)The detecting result of the five flavours of the decoction pieces(such as Huangbai,Zhizi,Kushen,Shengshaishen,Zhimu,Shengdahuang,Shenghuangqi,and Zhiwuzhuyu) largely approximate the delineation in《Pharmacopoeia of the People's Republic of China》(2005)and have a better discrimination.Apart from them,individual medicine(like Yinyanghuo and Zhifuzi) have bitter taste primarily,but pungent taste,sweet taste.(2) It is the first time that the five flavours of the six Chinese herbal formula(Huanglian Jiedu Decoction,Liaoben Zishen Pill,Dahuang Fuzi Decoction,Zuojin Pill,Shenfu Decoction and Wuzhuyu Decoction) have a good description.(3)The five flavours of the active Chinese herbal ingredients(Berberine,chrysophanol,emodin,jasminoidin,timosaponin,icariin and myoctonine) are firstly inscribed and similar to corresponding decoction pieces,excepting chrysophanol and timosaponin.Conclusion: By this method,the five flavours of traditional Chinese drug(Chinese herbal formula,Chinese herbal formula,the active Chinese herbal ingredients) can be detected and quantified accurately,it is beneficial to have the existing traditional Chinese medicine confirmed and have the contemporary new traditional Chinese medicine medicine get a standard research and development
