摘要:

建立了HPLC法测定海风藤药材中海风藤酮含量的方法,采用Hypersil ODS2柱(4.6×250 mm,5 μm),甲醇-水(70:30)为流动相,流速为1.0 mL/min;检测波长280 nm;海风藤酮在116~1160 μg/mL范围内线性关系良好,回归方程为Y=4561.1X–10927(r = 0.9994),平均回收率为99.83%,RSD=1.08%(n=6)。用本方法测得海风藤酮在风藤、石南藤和山蒟中的含量分别为0.25%,0.0057%和0.0014%。

Abstract:

An HPLC method was established to determine the content of kadsurenone in three kinds of Caulis Piper kadsurae. The sample was analyzed on ODS2 Column (4.6×250 mm, 5 μm), with the mobile phase of methanol-water (70:30), the detection wavelength of 280 nm, and the flow rate of 1.0 mL/min. The linear range was from 116 to 1160 μg/mL for kadsurenone. The regression equation was Y=4561.1X–10927 (r = 0.9994) and the average recovery was 99.83% with RSD=1.08 % (n=6). The content of kadsurenone in P. kadsura, P. wallichii and P. hancei was 0.25%, 0.0057%, and 0.0014%, respectively.
