摘要(Abstract):

目的:建立生姜超临界提取物的标准指纹图谱。方法:采用HPLC,选用依利特C18色谱柱(4.6 mm×250 mm,5μm),以乙腈-0.1%磷酸溶液为流动相梯度洗脱,流速1.0 mL.m in-1,检测波长278 nm,柱温25℃。结果:精密度、稳定性、重现性各实验图谱的相似度均大于0.9。结论:可以将生姜超临界提取物的指纹图谱检查列入质量控制标准。
Objective: To establish a standard fingerprint of SFE ginger extract.Method: HPLC method was used with elite hypersil ODS column(4.6 mm×25 cm,5 μm);mobile phase was acetonitrile-0.1% phosphoric acid solution mixture in gradient mode with a flow rate of 1.0 mL·min-1;detection length was 280 nm;column temperature was 25 ℃.Result: The similarity of every fingerprints was bagger than 0.9 in precision tests,stability tests and repeation tests.Conclusion: The method can be used for the quality control of SFE ginger extract.
