摘要
目的:建立独一味胶囊(独一味)中木犀草素、异鼠李素的含量测定方法。方法:采用HPLC法,伊利特C18柱,以甲醇水(50∶50),磷酸调节pH值至3.0,流速:0.8mL·min-1,检测波长:360nm。结果:木犀草素在7.072～35.360μg·mL-1,异鼠李素在1.658～8.290μg·mL-1范围内呈良好的线性关系,r木=0.9997,r异=0.9992。平均回收率分别为96.3,97.3,RSD分别为2.7,2.1。结论:本方法专属性强,灵敏度高,重现性好,适于独一味制剂中黄酮类成分的分离与测定。
AIM: To establish the method for determination of luteolin and isorhamnetin in Duyiwei Capsules (Lamiophl mis rotata(Benth.)Kudo). METHODS:Yilite-C_(18) column was used.The mobile phase was composed of methanol-water(50∶50),pH was adjusted to 3.0 with H_3PO_4.The flow rate was 0.8 mL·min^(-1) and detection wave-length was set at 360 nm. RESULTS:The linear range of Luteolin was 7.072-35.360 μg·mL^(-1),(r=(0.999 7)) and the linear range of isorhamnetin was 1.658-8.290 μg·mL^(-1)(r=0.999 2). The average recovery and RSD of luteolin were 96.3% and 2.7%,respectively. The average recovery and RSD of isorhamnetin were 97.3% and 2.1%,respectively. CONCLUSION:This method is sensitive,accurate and can be used for the quality study of Duyiwei Capsules.
