Study on Infrared Fingerprint of Sculellaria brbata

半枝莲药材红外指纹图谱分析（英文）

[Objective] This study was conducted to establish the characteristic finger- prints of herbal materials in the Weinan section of the Yellow River Wetland. [Method] Scutellaria barbata materials were collected from the Weinan section of the Yellow River Wetland. Fingerprint analysis was performed using their mid-IR spectra, and an IR fingerprint analysis method of S. barbata was established.[Result] The four collected S. barbata materials had basically the same IR finger- print characteristics, [Conclusion] S. barbata was identified by IR fingerprint method, and FTIR could serve as a rapid and scientific detection means for macro-control of S. barbata materials.

[目的]建立黄河湿地渭南段药材特征指纹图谱。[方法]采集黄河湿地渭南段的半枝莲药材,采用溴化钾压片法,利用中红外光谱对样品进行指纹图谱分析,建立了半枝莲药材红外指纹图谱分析方法。[结果]所采集4份半枝莲样品红外指纹特征基本相同。[结论]采用红外指纹图谱法可以对半枝莲进行有效的鉴定,FTIR可以作为半枝莲药材质量宏观控制的一个快速、科学的检测手段。
