Comprehensive quality evaluation of Jieyu Anshen granules based on multi-indicator content determination and HPLC characteristic chromatogram combined with chemometrics
Objective:To establish a multi-component content determination and characteristic chromatogram method for Jieyu Anshen granules,combined with chemometrics,to comprehensively evaluate the quality of Jieyu Anshen granules.Methods:The separation was performed on a CAPCELL PAK MG Ⅱ C18(250 mm x4.6 mm,5 μm)column using acetonitrile(A)and 0.1%phosphoric acid aqueous solution(B)as the mobile phases with gradient elution at a flow rate of 1.0 mL·min-1.The column temperature was 30 ℃ and the detection wave-lengths were set at 237 nm and 335 nm.The analysis method was validated.Based on the multi-component con-tent determination method,characteristic chromatogram was established.The samples were analyzed and evaluated through chemometrics to identify the main factors affecting their quality.Results:A multi-component content determination method was established for Jieyu Anshen granules.The five components had good linear relation-ships within their respective ranges,with recovery rates ranging from 95.6%to 100.0%.And 145 batches of samples were tested,and a total of 54 batches were found to be unqualified,with a total unqualified rate of 37.2%.Establishing a characteristic chromatogram of Anshen granules,12 characteristic peaks were attributed to 6 medicinal herbs.Through chemometric analysis,it was found that there were certain differences in the quality of samples from 10 manufacturers.The quality of fried gardenia and stir-baked licorice was the key factor.Conclu-sion:The established multi-component content determination method and characteristic chromatogram method for Jieyu Anshen granules are convenient and reliable,and can be used for comprehensive evaluation of the quality of Jieyu Anshen granules.
