Abstract:
OBJECTIVETo study the result of removing impurity from water-extraction of Gutianquan-capsule with macro-reticular absorbing resin, chitosans clarification, water-extraction and alcohol-precipitation methods.
METHODCoefficient of Unguent of macro-reticular absorbing resin, chitosans clarification method, water-extraction and alcohol-precipitation methods were compared, and qualitative assay of Ginsenoside Rg1, Re, and snide measurement of Ginsenoside Rg1, Ferulic acid, and stability experiment were made.
RESULTCoefficient of Unguent of water-extraction and alcohol-precipitation method was 17.2%, Coefficient of Unguent of chitosans clarification method was 12.8%, and macro-reticular absorbing resin method was 3.1%. They could clarify liquor of water-extraction.
CONCLUSIONChitosans clarification method is suitable for process of Gutianquan-capsule.
