경뇌강환%황기갑감%HPLC-ELSD%함량측정
Jingnaokang Pill%Astragaloside IV%HPLC-DLSD%Content determination
目的:建立颈脑康丸中黄芪甲苷的含量测定方法。方法:采用超声提取+柱纯化分离制备供试品溶液,HPLC-ELSD法测定,使用Agilent HC-C18 Analytical (5μm,4.6mm ×250mm)色谱柱,以乙腈-水(36∶64)为流动相,流速为1.0 ml·min-1,漂移管温度70℃,氮气流量为2.8L·min-1。结果:黄芪甲苷在0.032~0.32 mg·ml-1的范围内线性关系良好,其对数的线性方程为y=0.6615x-3.9805(r=0.9999),平均回收率为96.77%,RSD=0.66%(n=6)。结论:本方法准确可靠,重现性好,结果稳定,可作为该制剂的质量控制。

목적:건립경뇌강환중황기갑감적함량측정방법。방법:채용초성제취+주순화분리제비공시품용액,HPLC-ELSD법측정,사용Agilent HC-C18 Analytical (5μm,4.6mm ×250mm)색보주,이을정-수(36∶64)위류동상,류속위1.0 ml·min-1,표이관온도70℃,담기류량위2.8L·min-1。결과:황기갑감재0.032~0.32 mg·ml-1적범위내선성관계량호,기대수적선성방정위y=0.6615x-3.9805(r=0.9999),평균회수솔위96.77%,RSD=0.66%(n=6)。결론:본방법준학가고,중현성호,결과은정,가작위해제제적질량공제。
Object:To establish the method for the content determination of astragaloside IV in Jingnaokang Pill. Methods:U-sing the technology of Ultrasonic Extraction and Solid-Phase Extraction to prepare Testing Solution.HPLC-ELSD method was carried on a column of Agilent HC-C18 Analytical column (5μm,4.6mm ×250mm)with acetonitrile-water (36∶64)as mobile phase, drift tube temperature at 70 ℃,N2 flow being 2.8 L·min-1 ,and the flow rate being 1.0 ml·min-1. Results:There was a good linear relationship in the concent ration range of 0.032 ~0.32 mg · ml-1 ,the linear equation is y =0.6615x -3.9805 (r =0.9999).The average recovery was 96.77% ,with RSD=0.66% (n=6). Conclusion:This method is accurate,reliable,re-producible and stable,and can be applied to the quality control of the preparation.
