ABSTRACT
Objective To establish quantitative analysis of multi-components by single marker (QAMS) method for simultaneous determining the content of ten flavonoids in Kunxian Capsules (KC), and evaluate the adaptation and application of QAMS method in the quality control of KC. Methods The relative factor (fs/i) of epimedin A, epimedin C, epimedin B, icariin, luteolin, quercetin, nobiletin, kaempferol and baohuoside I were established by HPLC method with hyperoside as internal standard, which were used to calculate the content of ten flavonoids in the samples of KC. Meanwhile, external standard method (ESM) was used to calculate the content of ten flavonoids. The difference between QAMS and ESM were analyzed to evaluate the accuracy of QAMS. T-test was used to compare the content of ten flavonoids in KC. Results The fs/i of epimedin A, epimedin C, epimedin B, icariin, luteolin, quercetin, nobiletin, kaempferol, and baohuoside I were 0.756 5, 2.199 4, 1.232 7, 1.008 5, 0.635 7, 0.576 0, 0.487 5, 0.545 6, 0.675 8. The content determination results of ten batches of KC samples were calculated by the method of QAMS and ESM, with no significant difference in RSD < 2.0%. Conclusion The fs/i established in the QAMS method with hyperoside as the internal reference substance is accurate and feasible. The QAMS method can be used for the quality evaluation of KC.
