摘 要:目的建立HPLC法同时测定金莲花中色氨酸、对羟基苯甲苹果酸、荭草素-2”-O-β—L-半乳糖苷、荭草素、牡荆素的含量。方法以Phenomenex GeminiC。8色谱柱(4.6mm×250mm,5Ixm),乙腈-0.1%磷酸水溶液梯度洗脱,流速1ml·min^-1,柱温35℃C,检测波长230Bin。结果5种成分均达到基线分离,线性关系良好(r≥0.9987),平均加样回收率为95.05%-103.5%,RSD〈3%。结论该方法灵敏、准确、可靠、重复性好,可用于金莲花药材的质量评价。Objective To establish a HPLC method for the simultaneous determination of tryptophan,2 - (4 -hydroxybenzyl)ma- lic acid, 2 - O - β - L - galactopyranosylorientin, orientin, vitexin in Trollius chinensis Bge. Methods A Phenomenex Gemini C 18 column (4.6 mm× 250 mm, 5 μm) was used with acetonitrile and 0.1% H3 PO4 as mobile phase, the flow rate was 1 ml.min^-1, the detection wavelength was 230 nm, and the column temperature was 35 ℃. Results The 5 components were in baseline separation. The linearity of this method was good (r≥0. 998 7), and the average recoveries were between 95.05% and 103.5%, RSD 〈 3%. Conclusion The method is sensitive, accurate, reliable and repeatable, which can be used for quality evaluation of Trollius chinensis Bge.
