摘 要:目的:测定不同品种、不同产地溪黄草咖啡酸与迷迭香酸的含量。方法:采用HPLC,Dikma Diamonsil(2)(C184.6 mm×250 mm,5μm)色谱柱,以乙腈-0.3%磷酸为流动相梯度洗脱,流速1.0 mL.min-1,柱温室温,检测波长329 nm。结果:咖啡酸和迷迭香酸的线性范围分别为0.045 4~0.908 0μg(r=0.999 6)和0.219 2~4.384 0μg(r=0.999 9),平均回收率(n=5)分别为97.33%(RSD 2.20%),103.32%(RSD 1.84%)。不同品种、不同产地溪黄草药材中咖啡酸、迷迭香酸的含量差异较大,其中纤花变种的溪黄草两者的平均含量最高。结论:该方法简单快捷,适合于溪黄草中酚酸成分的含量测定研究,为溪黄草的质量控制提供了依据。Objective: To establish a HPLC method for the determination of caffeic acid and rosmarinic acid in Rabdosia serra from different species and different habitat. Method: HPLC method was performed on a Dikma Diamonsil (2) (Cls 4.6 mm ×250 mm, 5μm) with a mobile phase of methanol-0.3% phosphoric acid as mobile phase by gradient elution. The fl0w rate was 1.0 mL ~ min- 1, column temperature was kept at 25 ~C and detection wavelength was set at 329 nm. Result: Caffeic acid and rosmarinic acid showed good linearity in the ranges of 0. 045 4-0. 908 0 Ixg (r =0. 999 6) and 0. 219 2-4. 384 0 μg (r =0. 999 9 with average recoveries of 98.7% and 103.0% , respectively. The content of caffeic acid and rosmarinic acid in Rabdosia serra from different species and different habitat, and the content of both in R. lophanthoides was the highest. Conclusion: The method is simple, rapid for determination the content of caffeic acid and rosmarinic acid in R. serra, and can be used as the quality control of I. lophanthoides.
