The establishment of QAMS method for the simultaneous determination of eight components in Anshen Yinao pills / 国际药学研究杂志

ABSTRACT

Objective:To establish a method of the quantitative analysis of multi-components by single-marker (QAMS)for the simultaneous determination of content of the 8 components, demethylwedelolactone, wedelolactone, juju-boside A, jujuboside B, betulinic acid, salidroside, ligustroflavone and specnuezhenide, in Anshen Yinao pills. Meth-ods Anshen Yinao pills were used as the research object. With salidroside as an internal reference substance, the rela-tive correction factor for the other 7 components was established and the content of each component was calculated with each of the relative correction factors. Meanwhile, the content of each component was determined by the external standard (ES)method, and the content values from the ES and QAMS methods were compared to validate the accuracy and reli-ability of the QAMS method. Results: The eight components showed a good linearity within the given concentration rang-es(r≥0.9991). The average recovery for the eight components was in the range of 96.99-100.07%(n=9)with the RSD ranged in 0.67%-1.46%. The contents of the eight components showed no significant difference between the data mea-sured by the ES method and the data calculated by the QAMS method. Conclusion: The established method is simple and accurate, which could be used for quality evaluation of Anshen Yinao pills.
