Pharmacognostic Studies on Rhizoma Arisaematis / 中成药

ABSTRACT

Objective: To establish the identification of protein compositions in Rhizoma Arisaematis through researches of its taxonomy, pharmacognostic anatomy and chemical compositions.Methods: The protein compositions in Rhizoma Arisaematis were identified by HPCE taking potassium phosphate boric acid buffer solution (pH=9.0) as an electrophoretic buffer. The electric sampling time was 10s, 10kV; Separating pressure 25kV; column temperature=28℃;?=205nm; integral determination sensitivety value=0.05; sensitivity=0.1 AUFS. Also, the raw plant identification, medical material characteristics and microscope identification were performed. Results: Combined with pharmacognostic and microscopic identification, experiments indicated that herbs of Arisaematis genus have similar HPCE chromatographic profile but different finger peaks. Condlusion This study provides a better basis for the identification of Rhizoma Arisaematis.
