Abstract:
OBJECTIVETo determine the change pattern of alkaline and acid components of Fuzi and gancao amoung different combinations in Sini Decotion.
METHODThe contents of aconite alkaloids and glycyrrhizic acid were determined by HPLC in samples of Fuzi extracts, gancao extracts, Fuzi and gancao pair medicines extracts, and extracts of whole recipe.
RESULTAs for Fuzi, monoester aconite alkaloids could be detected in water extracts, and both biester and monoester aconite alkaloids could be detected in ethanol extracts. The contents of aconite alkaloids were decreased with changes of combinations: from Fuzi alone to pair medicines, and to whole recipe. The change pattern was more apparent when extracted in water decoction. As for Gancao, the glycyrrhizic acid was lowered from single medicine to pair medicines, and to whole recipe.
CONCLUSIONThe contents of alkaline and acid components were changed with different extract methods and different combinations of Fuzi and Gancao.
