摘　　要：为建立银杏叶提取物的指纹图谱提供参考依据,分别对不同分离纯化方法制备的银杏叶提取物进行傅里叶变换红外光谱(FTIR)和热分析(TG-DTG)测定,并对相关的谱图进行了特征分析。通过对各谱图比较分析结果表明,不同制备工艺的银杏叶提取物的FTIR和TG-DTG谱图的都有其各自的物质特征,FTIR和TG-DTG给出的是样品的整体信息,提供的信息能很好地反映银杏叶提取物的整体性,比单一指标成分的测定所提供的信息要更多、更有特征。Ginkgo biloba L.were extracted by different methods.The character of FTIR and Thermal Chart on extracts of G.biloba L. were analyzed.Comparision of the FTIR and Thermal Chart on different extracts showed that the FTIR and Thermal Chart for the samples from different methods possessed different substance characters.FTIR and Thermal Chart presented the whole information that could better represent the panorama of extracts of G.biloba L.than information of single index,and gave references for fingerprint of ex...
