不同采收期的银杏叶FTIR图谱特征分析

对不同采收期的银杏叶进行FTIR扫描测定，凭借直观而相对量化的红外特征峰的相对强度来阐明不同采收期银杏叶各组分的全貌．结果表明，不同采收期银杏叶的FTIR谱图都有其各自的物质特征．银杏叶FTIR图谱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组分的整体性，比单一指标成分的测定所提供的信息要更多、更有特征，适合对银杏叶的质量进行快速宏观整体评价，此谱图有助于特征确定其合理的采收期．

Characteristic Analysis of the FTIR Spectrogram of Ginkgo Biloba Leaves in Different Collecting Seasons

Ginkgo biloba L. in different havest seasons were determined by FTIR equipment in this article. The panorama of Ginkgo Biloba L. in different harvest seasons were illuminated by relative quantitative intensity of infrared characteristic peaks. The FTIR spectrometry of Ginkgo Biloba L. in different harvest seasons have different substance characters. The FTIR spectrometry present the more and better information about the panorama of Ginkgo Biloba L than that from single index ingredient, and is fit for evaluating the macroscopical quality. This help to ascertain reasonable seasons for Ginkgo Biloba L harvesting.
