Achyranthes bidentata is listed as the top grade in the Shennong Herbal Classic.In recent years,domestic and for-eign studies have confirmed there are many types chemical in A.bidentata,including steroids,triterpenoid saponins,polysac-charides and essential oil,which have anti-inflammatory and analgesic effects,immune regulation,anti osteoporosis and cardi-ovascular protection.Based on the plant's phylogenetic relationship,the effectiveness of its chemical components,the detect-ability of its chemical composition and changes of chemical components after processing are made on the potential quality markers(Q-Marker)of A.bidentata.It was preliminarily predicted that achyranterone A,25R-inokosterone,25S-inokos-terone,oleanolic acid-3-O-β-D-(6'-butyl ester)-glucuronopyranoside,oleanolic acid-3-O-β-D-(6'-methyl ester)-glucuronopy-ranoside and hydroxyecdysone etc.can be potential quality markers of A.bidentata.This review aims to provide the scientific evidence for establishing the quality control and further studying its pharmacological effects of A.bidentata.
