摘　　要：建立快速鉴别不同产地佛手的方法。【方法】采用傅立叶变换红外光谱法(FTIR)直接测定3种不同产地的佛手,根据特征吸收峰的峰位、吸收强度及峰高比的量化指标I值,进行比较分析。【结果】每个产地的佛手峰高比I值都有固定的范围,广佛手为0．7～0．9,川佛手为1．3～1．6,金佛手为0．9～1．1,根据I值的大小可以初步判断其产地。【结论】FTIR为广佛手、川佛手、金佛手3种不同产地佛手鉴别的有效方法,该法具有无需分离提取,无需化学处理,简便、迅速、稳定、实用的特点。[ Objective] To establish a method for rapid identification of Fructus Cirri Sarcodactylis （FCS） from different production areas. [ Methods] Fourier transform infrared （FTIR） spectroscopy was adopted to identify FCS, The height and position of the eharaeteristic absorption peaks, and I value （ a quantitative parameter of peak height ratio） were compared in FCS from different production areas. [ Results] Each kind of FCS had their fixed range in peak height ratio I： 0.7 - 0.9 in FCS from Guaogdong, 1.3 - 1.6 in FCS from Sichuan, 0.9 - 1.1 in FCS from Zhejiang, indicating that I value can be used to identify FCS from different areas . [ Conclusion ] For the identification of FCS from different production areas, FTIR spectroscopy is an effective method, in which there is no need tbr isolation, purification and chemical treatment.
