摘　　要：目的：建立红外指纹图谱法（FTIR）鉴别姜黄属常用药材的方法。方法：姜黄属四种常用药材姜黄、黄丝郁金、绿丝郁金、莪术采用80％乙醇，无水乙醇，丙酮，乙醚进行提取，提取物用氯仿充分溶解后采用液膜法分别测定400～4000cm^-1，范围内各提取物的红外吸收光谱，依据各药材提取物的各自特征吸收峰鉴别各药材。结果：4种药材的4种溶剂提取物的红外吸收峰明显不同，可作为鉴别药材和质量控制的手段之一。结论：该法可用于姜黄属4种常用药材的鉴别，操作简便，方法可靠。AIM ： To establish the method for identifying the herbs of Curcuma. METHODS ： Medicinal materials were extracted by 4 solvents such as, 80% ethanol, absolute alcohol, acetone and ether, the extracts were dissolved in CHCl3 and detected within 400-4 000cm^-1 by liquid-film method of FIR spectrophotometry. Comparing absorption maximum of different extractions including the location and intensities of peaks. RESULTS： The FIR spectra of these herbal drugs gave different maximum absorption peaks in number and intensity. CONCLUSION： The method is both simple and accurate and can be used to distinguish four kinds of Curcuma speies.
