摘要

应用自行设计的液晶光谱成像装置对不同地方居群的钩藤叶进行透射光谱检测分析。 绘制特征曲线, 构建成像特征图谱, 并对钩藤叶的特征光谱进行聚类分析。 分析结果显示: 钩藤叶的成像特征光谱相似度及其聚类分析对钩藤亲缘关系的判定结果与植物分类学鉴定结果相一致。 说明光谱成像分析技术可应用于探讨钩藤亲缘关系。 应用光谱成像分析技术设计的液晶光谱成像系统可对中药进行快速无损检测。 同一样品可反复进行多次实验, 实验操作方法简便快捷。 可为中药研究提供新的检测方法。

Abstract

In the present paper, using designed liquid crystal spectral imaging device, the transmission spectra of leaves of uncaria were detected and analysed under different environmental situations. The characteristic curve was drawn and the imaging characteristic spectrum was constructed and cluster analysis was performed. The results showed the similarity of imaging characteristic spectrum of uncaria leaves and the results of determining genetic relationship in cluster analysis were consistent with the results of the identification of plant taxonomy. Spectral imaging analysis techniques can be applied to discuss the genetic relationship of uncaria. The liquid crystal spectral imaging system can detect traditional Chinese medicine rapidly and nondestructively. The same sample can be used to repeat several experiments. Experimental operation is simple and quick. It can provide a new detection method for Chinese medicine.
