        ABSTRACT    OBJECTIVE:To study the composition and contents of flavonoids chemical components in waste material during
        industrialization of Pueraria thomsonii resources, and to provide reference for comprehensive development and reasonable
        utilization of the variety. METHODS:Using“No. 2 Gange”of P. thomsonii from Jiangxi as objects,UPLC-Q-TOF-MS and HPLC
        method were adopted to detect the components and contents of flavonoids in the root(with or without cortex),cortex,flower,
        fibrous root,stem,head and dregs(with or without cortex)of P. thomsonii as well as dry matter of industrial wastewater(with or
        without cortex)after precipitation of pueraria powder. RESULTS:The linearity,precision,repeatability,stability and recovery of
        the established method for content determination of 7 flavonoids (puerarin,daidzin,iridoxine-7-O-xylose glucoside,genistin,
        iridin,daidzein and kakkalide)were all in line with the requirements. Totally 12 kinds of flavonoids were identified,among which
        the flavonoids in the root,cortex,stem,fibrous root,head and dregs of P. thomsonii as well as dry matter of industrial wastewater
        were the same,mainly were puerarin,daidzin,genistein,daidzein and malonyl-daidzein. The flower of P. thomsonii mainly
        included iridoxine-7-O-xylose glucoside,genistin,iridin,kakkalide,6″-O-xylosyldaidzein,but the components as puerarin,
        daidzin and its aglycone were not be detected. The content of puerarin in the head of P. thomsonii was the highest(5.765%). The
        contents of puerarin in root and dregs of P. thomsonii as well as dry matter of industrial waste-water in samples with cortex were all
        higher than in corresponding peeled sample. CONCLUSIONS:The waste material from the industrialization of P. thomsonii
        resources contains a lot of flavonoids with rich species and high content,and can be used as an important raw material for
        obtaining flavonoids such as puerarin.
