The chemical component dynamic changes in compatibility of Carthamus tinctorius L. with Glycyrrhiza uralensis Fisch / 中成药

ABSTRACT

AIM: To study the dynamic change of chemical components in the compatibility of Carthamus tinctorius L.with Glycyrrhiza uralensis Fisch during decoction together. METHODS: By means of HPLC analysis and phytochemical isolation technique,focusing on the differences between chemical components in co-decoction and individual decoction.Two chemical substances which showed quantitative changes during co-decoction had been isolated and identified as Licochalcone A and Licochalcone B,respectively. CONCLUSION: From the method described in this article,it could be concluded that the chemical profiles of TCM drug-pairs prepared by co-decoction are different from that of extract mixture combined by the individual extract of Carthamus tinctorius L.and Clycyrrhiza uralensis Fisch,respectively.
