摘  要:目的:建立测定拟缺香茶菜药材中二萜类成分 Kamebacetal-A 、Kamebacetal-B、肾形香茶菜丙素的方法。方法采用固相萃取-高效液相色谱法(SPE-HPLC)测定3个二萜类成分的含量。使用Venusil C18(4.6 mm ×250 mm,5μm)反相色谱柱;流动相:乙腈(A)-水(B)梯度洗脱;流速:1 mL/min;柱温:30℃;检测波长230 nm。结果拟缺香茶菜中 Kamebacetal-A 、Kamebacetal-B、肾形香茶菜丙素分别在0.056~0.448 g/L(r =0.9992),0.0026~0.0208 g/L(r =0.9994),0.016~0.128 g/L(r =0.9997)内与峰面积成良好的线性关系;平均回收率分别为97.53%(RSD =2.16%),96.02%(RSD =2.01%),98.23%(RSD =2.10%)。结论所建立的方法灵敏、准确、稳定,可用于拟缺香茶菜中 Kamebacetal-A 、Kamebacetal-B、肾形香茶菜丙素的含量测定,为拟缺香茶菜抗肿瘤谱效关系的研究奠定基础。Objective To establish a method to simultaneously determine three diterpenoids in Isodon ex-cisoides.Methods The procedure of SPE-HPLC was performed on a Venusil C18 column(4.6 mm ×250 mm,5 μm).The mobile phases was water and acetonitrile in gradient mode (0 ~12 min,32%A;12 ~18 min,32 ~45%A;18 ~35 min,45%A).The flow rate was 1.0 mL·min -1 .The column tempera-ture was 30℃.The UV detection wave length was 230 nm.Results All the standard compounds showed a good linearity in the range of 0.056 ~0.448 g/L (r =0.999 2),0.002 6 ~0.020 8 g/L (r =0.999 4),0.016 ~0.128 g/L(r =0.999 7)for Kamebacetal-A,Kamebacetal-B,and Reniformin C, respectively.The average recoveries of the three diterpenoids were 97.53%,96.02%,98.23% with RSD 2.16%,2.01%,and 2.10%,respectively.Conclusion This method is simple,accurate and ef-fective.It could be used for quality control of ingredients in Isodon excisoides.It could also provide refer-ence for the study of antitumor activity spectrum.
