不同产地姜厚朴饮片气相指纹图谱的探讨

目的比较不同产地姜厚朴气相指纹图谱，以确定最佳指纹图谱模式。方法用气相色谱法分别对10批次的湖北恩施GAP示范基地、湖北房县、甘肃文县的姜厚朴饮片进行分析。结果经比较发现，恩施GAP产地的姜厚朴饮片有13个共有峰，共有峰的重叠率为100％，而且有效活性成分含量是不同产地中为最高，可以将指纹图谱来鉴别姜厚朴的饮片。初步确立恩施GAP产地的姜厚朴饮片气相图谱为最佳的指纹图谱模式。结论此方法准确，操作简单，能快速有效鉴别姜厚朴饮片。

Study on Identifying Jiang Magnolia Puerariae from Different Producing Areas by Fingerprint of GC

Objective： Compare Jiang Magnolia Puerariae from different producing areas by fingerprint of GC. Method： Ultraviolet Spectrum Group method was adopted to analyze respectively 10 batches of Jiang Magnolia Puerariae from Hubei Enshi GAP demonstration base, Hubei Fangxian region and Gansu Wenxian region. Results： Through comparison, we discovered the every Jiang Magnolia Puerariae Gasphase Chromatogram of Hubei Enshi GAP demonstration base had 13 same peaks, the overlapping coefficient of same peaks was 100% , and the contents of active ingredient was the highest of different producing areas. So we can regard it as Fingerprint of GC and use it on differentiating Jiang Magnolia Puerariae. Conclusion ： The method is easy and efficient to identify Jiang Magnolia Puerariae.
