To establish quality standard of Mongolian crude drug Huderinaidurijide.Methods:According to relevant methods in Chinese Pharmacopoeia(2015 edition Ⅳ),impurity,moisture,ash and extract of Huderinaidurijide were tested.A silica gel G plate was used.Euphol was taken as a control.Petroleum ether(60~90 ℃)-ethyl acetate(10:1)was used as developing solvent and 10% sulfuric acid ethanol solution was used for color development.Huderinaidurijide was performed identification.UV spectrophotometry was applied.Taking euphol as a control,active ingredients-terpenoids of Huderinaidurijide were quantitatively analyzed at 545 nm wavelength.Results:The impurity of 3 batches of sample Huderinaidurijide was 0.69%~0.75%,with an average of 0.72% and a RSD of 4.26%.The moisture content ranged from 7.68%~7.74%,with an average of 7.72% and a RSD of 0.03%.The total ash was between 0.20% and 0.22%,with an average of 0.21% and a RSD of 2.86%.The acid-insoluble ash ranged from 0.21%~0.23%,with an average of 0.22% and a RSD of 4.82%.The extract ranged from 1.24 to 1.35,with an average of 1.31% and a RSD of 4.64%.In the chromatogram of the test product,spots of the same color were displayed at positions corresponding to the chromatogram of the control product.The total terpenoids showed a good linear relationship between 0.6720 and 5.3790 mg/L.The average recovery rate of this method was 97.48% and the RSD was 0.478%.The content of total terpenoids in the 3 batches of samples ranged from 25.67 to 35.94 mg/g,with an average of 31.03 mg/g.Conclusion:According to the results,it is formulated that impurity,moisture,total ash,and acid-insoluble ash in Mongolian crude drug Huderinaidurijide(calculated on dried products)can not exceed 1%,10.0%,0.4% and 0.4%,respectively.Water-soluble extract is not less than 1.0%.The content of total terpenoids is not less than 20 mg/g.This method can be used for quality control of Mongolian crude drug Huderinaidurijide.
