广西不同产地龙眼叶药材红外指纹图谱研究

Infrared Fingerprint Study of the Leaf of Dimocarpus longan Lour. from Guangxi

目的建立广西不同产地龙眼叶药材的红外指纹图谱。方法采用傅里叶变换红外光谱法测定广西不同产地龙眼叶药材,并应用红外Omic软件对实验数据进行处理。结果实验建立了广西龙眼叶药材红外特征指纹图谱共有模式,标定了5个共有峰。结论该方法专属性强、快速、稳定,可用于广西产龙眼叶药材的质量评价。

Objective This study aimed to establish the infrared （IR） fingerprint for the leaf of Dimocarpus.longan Lour. in Guangxi. Methods The fingerprint was established by fourier transform infrared spectroscopy （ FT-IR）, and then analyzed by Omic software. Results The IR fingerprint of Dimocarpus longan Lour. was established. There were 5 common peaks common of 10 samples. Conclusion The specific ,rapid and stable method can be applied for quality control of the leaf of Dimocarpus longan Lour.
