Objective To establish an HPLC-DAD method for the simultaneous determination of amygdalin, oleanolic acid, ursolic acid, agrimol B, liquiritin, calycosin-7-glucoside, ruscogenin, gallic acid, psoralen, and shionone in Yifei Qinghua Granules (YQG). Methods The chromatographic separation was achieved on an Waters Symmetry-C₁₈ (250 mm×4.6 mm, 5.0 μm) column with mobile phase consisted of (1.0 g potassium phosphate monobasic in 1 000 mL water, the pH value was adjusted to 3.5 with phosphate)-(acetonitrile-methanol 1:1) for gradient elution, at the flow rate of 0.8 mL/min; The column temperature was 40℃. Results The linear ranges of amygdalin, oleanolic acid, ursolic acid, agrimol B, liquiritin, calycosin-7-glucoside, ruscogenin, gallic acid, psoralen, and shionone were 0.2-2.0 μg/mL (r=0.999 4), 0.4-4.0 μg/mL (r=0.999 4), 0.3-3.0 μg/mL (r=0.999 6), 0.1-1.0 μg/mL (r=0.999 3), 0.5-5.0 μg/mL (r=0.999 1), 0.15-1.50 μg/mL (r=0.999 2), 0.25-2.50 μg/mL (r=0.999 5), 0.6-6.0 μg/mL (r=0.999 1), 0.45-4.50 μg/mL (r=0.999 3), and 0.12-1.20 μg/mL (r=0.999 4), respectively. These ten components were well resolved. Their average recoveries (n=6) respectively were 98.7% (RSD=0.7%), 98.0% (RSD=1.3%), 99.6% (RSD=1.4%), 98.0% (RSD=1.4%), 99.1% (RSD=1.1%), 99.4% (RSD=0.8%), 98.8% (RSD=0.9%), 101.1% (RSD=0.5%), 100.6% (RSD=0.5%), and 101.7% (RSD=0.8%). The content of ten batches of the amygdalin, oleanolic acid, ursolic acid, agrimol B, liquiritin, calycosin-7-glucoside, ruscogenin, gallic acid, psoralen, and shionone was 0.104-0.123, 0.600-0.621, 0.501-0.523, 0.100-0.121, 0.103-0.122, 0.231-0.260, 0.043-0.065, 0.055-0.069, 0.061-0.079, 0.031-0.043 mg/g, respectively.
