摘要
目的:用松脂醇二葡萄糖苷为参照物,建立不同生长年限及不同品种类型的杜仲HPLC指纹图谱,以此为建立郴州大诚中药饮片有限责任公司GAP基地杜仲HPLC指纹图谱的企业质量标准提供依据。方法:采用ZORBAX Eclipse XDB-C18(250 mm×4.6 mm,5μm)色谱柱,流动相为甲醇-0.1%磷酸水,梯度洗脱,检测波长为277 nm,流速为1.0 ml·min^-1,柱温为25℃,进样量为5μl。结果:建立了以松脂醇二葡萄糖苷为参照物的杜仲HPLC指纹图谱,确定了14个共有峰,10批样品指纹图谱整体相似度均在0.939以上。结论:该方法简便,重复性好,HPLC指纹图谱可作为郴州大诚中药饮片有限责任公司GAP基地杜仲药材的企业质量标准。
To establish the HPLC fingerprints of Eucommia ulmoides at different ages of different varieties with pi-noresinol diglucoside as the reference material to provide the basis for the HPLC fingerprints in the enterprise quality standards of Eu-commia ulmoides from the GAP base of Chenzhou Dacheng Chinese Herbal Medicine Co. Ltd. . Methods： A column of ZORBAX E-clipse XDB-C18 （250 mmx 4. 6 mm, 5μm） was used. The mobile phase consisted of methanol-0. 1% phosphoric acid with gradient e-lusion. The detection wavelength was 277 nm, the column temperature was 25℃,the flow rate was 1. 0 ml·min-1 , and the injection volume was 5 μl. Results：The Eucommia ulmoides HPLC fingerprints including 14 common peaks were established with pinoresinol diglucoside as the reference material. The similarity of the HPLC fingerprints of 10 samples was over 0. 939. Conclusion：The method is accurate and reliable. The HPLC fingerprints can be used as the enterprise quality standards of Eucommia ulmoides for Chenzhou Dacheng Chinese Herbal Medicine Co. Ltd. .
