Abstract:
To extract medicinal materials of salvia miltorrhiza powder and both tanshinoneⅡA and cryptotanshinone component in knobble portion using ultrasonic extraction, the optimum extraction conditions are established about component of liposoluble in medicinal materials of danshen. Based on which it is explored how to extract a little bunch of component of liposoluble in medicinal materials of danshen, and the comparison is made on fingerprint picture between ultrasonic extraction and immersion extraction. The result shows that ultrasonic extraction is suitable to craft of medicine industry production. The structure of tanshinone ⅡA and cryptotanshinone gotten from the experiment is same as that of those obtained by soakage method. The optimum conditions are present as: the volume density is 90%, the rate of ethanol is 1:5, the extraction time is 45 min, the content of tanshinoneⅡA and cryptotanshinone in medicinal materials of danshen are 0.285 6% and 0.355 5%.
