摘 要:目的:HPLC法同时测定运脾散浸膏中柚皮苷、橙皮苷和苍术素的含量。方法:色谱柱:Thermo ODS-2(250 mm×4.6 mm,5μm);流动相:甲醇-水梯度洗脱,0-5 min(30%-40% A),5-15 min(40%-50%A),15-20 min(50%-79% A),20-30 min(79%-100% A),30-45 min(100% A),45-55 min(100%-30%A),55-60 min(30% A);柱温:30℃;检测波长:283 nm;流速:1 mL·min^-1。结果:柚皮苷、橙皮苷、苍术素线性范围分别为0.00916-0.13700μg(r=0.9999)、0.00622-0.09130μg(r=0.9998)、0.00358-0.05370μg(r=0.9999),平均回收率分别为103.51%、96.82%、97.65%,RSD分别为1.37%、1.41%、1.49%(n=6)。结论:本方法专属性强,重复性好,可用于运脾散浸膏中柚皮苷、橙皮苷和苍术素的含量测定。This study was aimed to simultaneously determinate the content of naringin, hesperidin and atractylodin in Y un-Pi (YP) Powder extract by HPLC. A Thermo ODS-2 column (250 mm × 4.6 mm, 5 μm) was used for the gra-dient elution with a methanol-water of 0-5 min (30%-40% A), 5-15 min (40%-50% A), 15-20 min (50%-79%A), 20-30 min (79%-100% A), 30-45 min (100% A), 45-55 min (100%-30% A), 55-60 min (30% A). The col-umn temperature was at 30℃. The detection wavelength was at 283 nm. The flow rate was 1 mL·min^-1. The linear range was determined to be 0.009 16-0.137 00 μg (r = 0.999 9), 0.006 22-0.091 30 μg (r = 0.999 8), 0.003 58-0.053 70 μg (r = 0.999 9), respectively for naringin, hesperidin and atractylodin. The average recovery rate of pterodontic acid was 103.51%, 96.82% and 97.65%. And RSD was 1.37%, 1.41%, 1.49% (n = 6). It was concluded that the method had good specificity and repeatability. It was considered as a good tool for the content determination of naringin, hesperidin and atractylodin in YP Powder extract.
