| 摘 要： | 目的:为荔枝草的最佳采收期提供实验依据。方法:采用Lichrospher C18色谱柱(4.6mm×150mm,5μm);0.5%的甲酸水溶液-乙腈梯度洗脱,流速1.0mL/min,柱温:25℃,检测波长342nm。结果:高车前苷与假荆芥属苷分别在0.0472～0.472μg(r=0.9999)和0.0275～0.275μg(r=0.9999)范围内呈良好的线性关系。结论:该方法简单,结果准确可靠,重现性好。荔枝草在5月上旬未开花前黄酮含量积累达到最大,可参考作为荔枝草药材的最佳采收期。

| Abstract: | Objection ： To determine the optimal collection period of Salvia plebeia R. Br.. Method ： The determination was performed on Lichrospher C18 column（4.6 mm ×150 mm,5 μm） ; A linear gradient elution of eluents A （0.5% （v/v） aqueous formic acid） and B （acetonitrile） was used for the separation, the flow rate was 1.0 mL · min - 1, the column temperature was kept at 30℃, the elution was monitored at the wavelength of 342 nm. Results ： The calibration of homeplantaginin and Nepetin - 7 - glueoside were linear in the ranges of 0. 0472 - 0. 472μg（ r = 0. 999 9 ） and 0. 0275 ～ 0. 275μg（ r = 0. 999 9）. Conclusion： The two flavanoids in May. It could be regarded as the Key words Salvia plebeia R. Br. compounds in Salvia plebeia R. Br. has the maximum accumulation optimal collection period of different collection period; Salvia plebeia R. Br.. homoplantaginin; nepetin - 7 - glucoside |
