摘要
目的:建立同时测定小儿解感片中芦丁、槲皮苷、橙皮苷、黄芩苷、汉黄芩苷、山奈酚及黄芩素7种黄酮类成分含量的方法。方法:采用高效液相色谱-电雾式检测器(HPLC-CAD)法,色谱柱为Waters XBridge C18(250 mm×4.6 mm,5μm),甲醇(A)-20 mmol·L-1乙酸铵(乙酸调pH至4.5)(B)为流动相,梯度洗脱,流速0.8 mL·min-1,柱温35℃,进样量20μL,CAD雾化器温度为35℃,过滤常数5.0。结果:芦丁、槲皮苷、橙皮苷、黄芩苷、汉黄芩苷、山奈酚及黄芩素检测质量浓度线性范围为0.28~5.60μg·mL-1(r=0.999 2),0.23~4.60μg·mL-1(r=0.999 6),0.17~3.40μg·mL-1(r=0.999 1),1.88~37.60μg·mL-1(r=0.999 6),0.51~10.20μg·mL-1(r=0.999 5),0.15~3.00μg·mL-1(r=0.999 4),0.16~3.20μg·mL-1(r=0.999 1);检测限分别为0.06,0.06,0.06,0.07,0.07,0.05,0.05μg·mL-1,定量限分别为0.17,0.16,0.16,0.18,0.19,0.13,0.13μg·mL-1;平均加样回收率分别为99.44%,98.83%,98.44%,98.60%,98.05%,99.02%及98.53%,RSD分别为1.70%,1.47%,0.89%,1.20%,1.13%,1.80%及1.32%(n=6)。结论:本法准确性好,灵敏度高,简便易行,可用于小儿解感片中多指标成分的质量控制研究。
