摘　　要：目的:建立测定人血浆中灯盏花素浓度的高效液相色谱法。方法:色谱柱Kromasil C18(4.6 mm×250 mm,5μm);流动相甲醇-水-冰醋酸(30∶70∶1)检测波长:335 nm;灯盏乙素作为内标,用HPLC测定人血浆中灯盏花素浓度。结果:灯盏花素线性范围为0.30～18.0 mg·L-1,回归方程Y=0.008 7C-0.001 56(r=0.999 6);回收率>80%,日内和日间RSD均<10%。结论:方法简便、快速、准确,适用于灯盏花素药代动力学研究及血药浓度监测。Objective：To establish a high performance liquid chromatographic method for determination the concentration of breviscapine in plasma of healthy volunteers.Method：The assay was conducted on the Kromasil C18（250 mm×4.6 mm,5 μm）columnn with methanol-water-glacial acetic acid（30∶70∶1）as the mobile phase.The detection wave length was set at 335 nm,and scutellarin was taken as the internal standard.Result：The linearity range was 0.30-18.0 mg·L-1 with a regressive equation of Y=0.008 7 C-0.001 56（r=0.999 6）.The recovery was above 80%,with both intra-day RSD and inter-day RSD below 10%.Conclusion：The method was shown to be convenient,rapid,accurate,and suitable for the pharmacokinetic study of breviscapine and monitoring its concentration in clinical application.
