Effect of Irradiating Salvia Miltiorrhiza Callus on the Accumulation of TanshinoneⅡ_A by laser

摘要： [Objective] To discuss the effect of irradiating callus of Salvia miltiorrhiza on the accumulation amount of TanshinoneⅡA by laser.[Method] The callus of Salvia miltiorrhiza was irradiated with different intensity of laser at different time,and then cultured for 60 days,the contents of TanshinoneⅡA in different treatments were determined by HPLC and compared with control group.[Result] There was no significant difference of the TanshinoneⅡA content between treatment group and control group.[Conclusion]The content of TanshinoneⅡA in the callus of Salvia miltiorrhiza has not been promoted significantly by laser irradiation. （共3頁）
