Changes of the Contents of the Active Components in 5 Chinese Medicinals after Combined with Aconite

Objective:To study the changes of the contents of the active components in white peony,ginseng,dried ginger, licorice,and rhubarb after they were combined with aconite and its processed products.Methods:Using paeoniflorin, ginsenoside,capsaicin,ammonium glycyrrhizate and emodin as the chemical reference standards,which were deter- mined by HPLC in 5 Chinese medicinals after they were combined with aconite and its products.Results:After com- bined with aconite,the contents of the active components in the combined decoctions were obviously lower than that in the decoctions of individual medicinals.Conclusion:When aconite was combined with white peony,ginseng,dried gin- ger,licorice,or rhubarb,the toxicity of aconite was decreased;The active components of the medicinals combined with aconite were influenced,and as well.
