OBJECTIVE To refine hydroxysaffloryellow A(HSYA).METHODS Based on the HSYA which was the index to evaluate the refining conditions.In this way,such conditions as concentration of the ethanol,the quantity of the Ethanol and the pH were investigated.RESULTS The concentration of the ethanol give more significant effect on the refined content of HSYA,and the second was the quantity of the ethanol and the pH.Furthermore using the way that adjust the pH in advance then adjust the concentration of the Ethanol,can obtain more refined HSYA. The concentration of the ethanol was 80%,pH was 6.5,and the concentration of the lixivium was 2∶1 that it is the best conditions of refining HSYA.
