| Abstract: | To investigate the effect of different methods of extraction for gentiopicrin.and swertiamarin in Radix Gentiana on the rate of extraction.HPLC method is applied,the four methods are investigated.The first method is extracted in ultrasonic bath with methanol;the second mathod is soaked in methanol for 12 h;the third method is boiling in water;the forth method is percolation with ethanol.The highest rate of extraction is the forth method;the best percolation method is determined.The established method is sample,practicable,productive,which can be used for analyzing the quality of Radix Gentiana. |
