比色-等导数值导数光谱法测定牛黄解毒片中胆酸含量

Application of Colorimetric-Equal Value Derivative Spectrometry to the Determination of Cholic Acid in Niuhuang Jiedu Pian(Tablet)

采用比色-等导数值导数光谱法测定由八味药材组的成牛黄解毒片中胆酸的含量,只经简单提取,不需分离即可排除冰片、大黄等多种药材的干扰,其平均回收率为99.75±0.79%((?)±CV)。

A colorimetric-equal value derivative spectrometry for the quantitative analysis of cholic acid in Niuhuang Jiedu Pian(tablet)containing 8 crude drugs is reported. The method is free from the interferuce of borneol rhubarb and other components without separation. The average recovery of cholic acid is 99.75±0.79%(X±CV).
