Abstract:
OBJECTIVETo demonstrate the solubility of Chinese herbal compound with solubility parameters.
METHODThe solubility parameters of Liangfu effective components and Liangfu compound were determined by inverse gas chromatograph (IGC) and group contribution. Hansen ball was plotting by HSPiP, which could be used to investigate the solubility of Liangfu effective components and Liangfu compound in different solvents. And the results were verified by approximate solubility.
RESULTLiangfu effective components and Liangfu compound could be dissolved in chloroform, ethyl acetate, acetone, octanol and ether, and were slightly soluble in glycerol, methanol, ethanol and propanediol, but could not be dissolved in water. They were all liposoluble, and the results were the same as the test results of the approximate solubility.
CONCLUSIONThe solubility of Chinese herbal compound can be expressed by solubility parameters, and it is accurate, convenient and visual.
