| titleOfInvention | The content assaying method of Multiple components in Yupingfeng preparation |
| abstract | The present invention relates to the content assaying method of Multiple components in a kind of Yupingfeng preparation, comprise the steps: that (1) takes Yupingfeng preparation, accurately weighed after pulverizing or not pulverizing, add methanol eddy and extract 1 3h, filter, add methanol constant volume after concentration, obtain need testing solution；(2) precision weighs reference substance macrotin glycosides, calycosin glucoside, macrotin, 5 O methyl visamminol glycosides, sec-o-glucosylhamaudol, calycosin, onocerin, atractylodes lactone III, atractylenolide Ⅰ, atractylenolide respectively, add methyl alcohol and dissolve constant volume, obtain mixing reference substance solution；(3) measure: precision draws need testing solution and mixing reference substance solution respectively, injects high performance liquid chromatograph, with certain flowing phase condition gradient elution, use multi-wavelength to monitor simultaneously, to obtain final product.The method can the simultaneously content of composition in 10 in Accurate Determining Yupingfeng preparation, it is possible to objective, comprehensively, reflection Yupingfeng quality of the pharmaceutical preparations situation delicately. |
