摘要 目的:建立RP-HPLC法同时测定西洋参总皂苷转化产物中人参皂苷Rg1、Rd、Rh1、Rg3和C-K的含量。方法:采用WelchromC18色谱柱(4.6mm×250mm,5μm);流动相为乙腈(A)-水(B),梯度洗脱;流速为1.0mL/min;柱温为30℃;检测波长为203nm。结果:人参皂苷Rg1,Rh1,Rd,Rg3和C-K的线性范围分别为0.740~7.400μg(r=0.9999);0.536~5.360μg(r=0.9999);1.128~11.280μg(r=0.9999);0.3080~3.080μg(r=0.9999);0.376~3.7600μg(r=0.9999)。平均加样回收率分别为97.12%(RSD=1.22%),98.50%(RSD=0.87%),98.00%(RSD=1.06%),98.12%(RSD=1.66%)和96.65%(RSD=1.48%)。结论:该法操作简便,结果可靠,适用于西洋参转化产物的含量测定。
