摘　　要：目的:考察蓝萼香茶菜不同部位蓝萼甲素的含量及最适采收期。方法:采用反相高效液相色谱法,色谱柱为岛津C18ODS,流动相为甲醇-水(60∶40),流速为0.9mL·min-1,柱温为25℃,于波长234nm条件下对样品中蓝萼甲素的含量进行测定。结果:以叶中蓝萼甲素含量最高,且7、8月份采集的叶中蓝萼甲素含量较高。结论:蓝萼香茶菜应在夏季采收,并以叶入药为宜。Objective： To study content of glaucocalyxin A in different part of Rabdosia japonica var. Glaucocalyx at different collected time and select the perfect time. Methods： HPLC was used to detect the content of glaucocalyxin A. HPLC separation was performed on Symmetry C18 column with a solvent system of methanol-water （60：40）, The detection wavelength was 234 nm. The flow rate was 1 mL.min-1. The column temperature was 25 ~C. Results： The content was the highest in leaves of Rabdosia japonica var which was collected in July and August. Conclusion： Rabdosia japonica var. Glaucocalyx＇s leaves should be collected at summer.
