一测多评法同时测定麻杏石甘口服液中3种成分含量

Simultaneous Determination of 3 Constituents in Maxing Shigan Oral Medicinal Liquid by HPLC-QAMS

建立麻杏石甘口服液中盐酸麻黄碱、盐酸伪麻黄碱和苦杏仁苷3种成分含量的一测多评方法。以盐酸麻黄碱为内参物,建立盐酸伪麻黄碱和苦杏仁苷与盐酸麻黄碱的相对校正因子,分别采用外标法与一测多评法测定3种成分的含量,比较两种方法测得结果的差异,验证一测多评方法的可行性。盐酸麻黄碱与盐酸伪麻黄碱、苦杏仁苷的相对校正因子分别为1.233和2.741,一测多评法与外标法测定结果无显著性差异,相对误差小于0.3%。一测多评法运用于麻杏石甘口服液的含量测定准确可行。

To establish a method of quantitative analysis of multi-components by single marker (QAMS) for the determination and evaluation of three constituents (ephedrine hydrochloride, pseudoephedrine hydrochloride and amygdalin)in Maxing Shigan Oral Medicinal Liquid.Ephedrine hydrochloride was used as internal reference substance, and the relative correction factors(RCF) of pseudoephedrine hydrochloride and amygdalin to ephedrine hydrochloride were calculated and evaluated. The content of the three components were determined by the external standard method(ESM) and QAMS, respectively. The difference between the two methods was compared to verify the feasibility of the method.The RCF of pseudoephedrine hydrochloride and amygdalin to ephedrine hydrochloride were 1.233 and 2.741, respectively. There was no significant differences between the results of external standard method and QAMS, and the relative error was less than 0.3 %.The QAMS method is feasible and accurate for the simultaneous determination of Maxing Shigan Oral Medicinal Liquid.
