ABSTRACT
Objective To study the different extraction methods for the content of tanshinoneⅡA in water decocted Radix Salviae Miltiorrhiza, in order to develop comprehensive utilization of Salvia miltiorrhiza. Method Tanshinone ⅡA was extracted by supercritical carbon dioxide fluid and compared with ultrasonic extraction. Result When the extraction pressure was 35 MPa, extraction temperature was 40 ℃, extraction time was 2 h and entrainer (ethanol) was 100 %, the yields of the tanshinone ⅡA was up to 3.87 mg, while the ultrasonic extraction was 2.89 mg. Conclusion TanshinoneⅡA extracted by supercritical carbon dioxide fluid was better than ultrasonic extraction and had higher purity. The comprehensive utilization of Salvia miltiorrhiza is available.
