To establish an HPLC characteristic chromatogram of Xifeng Huoluo capsules, and to determine the contents of gastrodin, amygdalin, strychnine, hydroxysafflower yellow A, brucine, paeoniflorin, ferulic acid, salvianolic acid B, cryptotanshinone, tanshinone Ⅰ, and tanshinone ⅡA.
Extraction of 75% methanol was analyzed by a Venusil MP C18 chromatographic column (250 mm×4.6 mm, 5 μm) using 0.1% phosphoric acid (A) -acetonitrile (B) as the mobile phase with gradient elution at a flow rate of 1.0 mL·min-1. The column temperature was 30 ℃. The detection wavelengths were variable. The characteristic chromatograms of 10 batches of Xifeng Huoluo capsules were evaluated by similarity evaluation, and the eleven identified index components were quantitatively determined.
There were thirty-one common peaks in the characteristic chromatograms of eleven batches of samples and the similarities were all above 0.99. The common peaks could ascribed to twelve medicinal materials, and eleven of them were identified. Eleven components showed good linearity within their respective ranges (r≥0.999 4), and the average recoveries were 99.3%-103.0% with RSDs of 1.5%-2.4%.
The established method has high sensitivity and strong specificity. The HPLC characteristic chromatogram combined with multi-component quantitative determination can fully reflect its inherent quality and can be used for the quality control of Xifeng Huoluo Capsules.
