ABSTRACT
OBJECTIVE:
To establish the identification method of Rhizoma Arisaematis and content determination of flavon-oids.METHODS:
TLC was used to identify Rhizoma Arisaematis with schaftoside and ischaftoside as reference substances.The content of flavonoids was determined by HPLC.RESULTS:
TLC of test sample and that of control substance had same color dots.The linear range of schaftoside and isoschaftoside were 7.925~126.8 ?g?mL-1(r=0.999 9) and 3.996~63.94 ?g?mL-1(r=0.999 7) respectively.Average recoveries were 99.4% for schaftoside (RSD=2.10%,n=9) and 99.52% for isoschaftoside(RSD=2.42%,n=9).CONCLUSION:
The method is simple,accurate and reproducible for the quality evaluation of Rhizoma Arisaematis.
