摘要:为建立海金沙全草的GC指纹图谱分析方法,采用毛细管气相色谱法测定了10个批次的海金沙样品GC指纹图谱.色谱条件:AT OV-17石英毛细管柱,程序升温40~200 ℃,进样口温度220 ℃,检测器(FID)温度220 ℃,分流比为20∶1.结果显示:海金沙药材的GC指纹图谱由14个特征峰构成,不同产地海金沙的GC指纹图谱有一定差异.本研究建立的GC指纹图谱有较好的稳定性和重现性,可作为海金沙药材质量控制的参考方法.

Abstract: Objective To establish a GC fingerprint analysis of Lygodium japonicum.Methods The fingerprint of Lygodium japonicum from 10 different regions was performed by capillary GC chromatography,AT OV-17 column was used,programmed temperature was from 40 to 200 ℃,sample injector temperature:220 ℃,FID detector temperature:220 ℃,split ratio:20∶1.Results GC fingerprint of Lygodium japonicum.consisted of 14 common peaks,but there was a certain difference of GC fingerprint of Lygodium japonicum between different producing areas.Conclusion The method gives good stability and reproducibility,and   provides a reference standard for the quality control of Lygodium japonicum.

Key words: Lygodium japonicum, volatile components, GC, fingerprint
