十全大补膏中芍药苷的含量测定

建立了高效液相色谱法测定十全大补膏中芍药苷含量的方法。采用Kromasil C_(18)色谱柱(4.6 mm×250 mm,5μm),以乙腈-水(17∶83,V/V)为流动相,柱温30℃,进样量10μL,检测波长230 nm,流速1.0 mL/min。结果表明,芍药苷在0.083 6~0.627 0μg范围内线性关系良好(r=0.999 8),加样回收率为98.98%~100.47%,相对标准偏差为0.65%(n=6)。本方法专属性强、灵敏度高、重现性好、操作简便,适用于十全大补膏的质量控制。

Content determination of paeoniflorin in tonic semifluidextract of ten ingredients

A HPLC method for the determination of paeoniflorin in tonic semifluid extract of ten ingredients was established. The HPLC analysis was performed on Kromasil C18 column (4.6 mm×250 mm, 5 μm), acetonitrile water (17∶83, V/V) as the mobile phase, and the column temperature was 30 ℃, injection volume was 10 μL, the detective wavelength was at 230 nm, at a flow rate of 1.0 mL／min. Results revealed that paeoniflorin at the content of 0.083 6～0.627 0 μg showed good linearity（r= 0.999 8），the recovery rate was 98.98%～100.47%, RSD was 0.65% (n=6). This method is highly specific, sensitive, reproducible, and simple, which can be used for the quality control of this preparation.
