摘要:目的:研究当归不同药用部位的近红外漫反射光谱(NIR)指纹图谱特征。方法:采集甘肃及云南共14个主产县的96批当归样本,以积分球漫反射方式采集NIR指纹图谱,采用相似度分析和偏最小二乘判别分析(PLS-DA)进行研究。结果:当归不同药用部位NIR指纹图谱的平均光谱有一定差异,特征吸收处吸光度大小为归身〉归尾〉归头〉全归;当归不同药用部位NIR指纹图谱的相似度多大于0.95;可以采用PLS-DA模型对当归不同药用部位进行明确的分类;当归不同药用部位NIR指纹图谱的差异主要表现在8 443-8 284 cm^-1、7 003-6 896cm^-1、6 102-5 864 cm^-1、4 847-4 674 cm^-1以及4 386-4 208 cm^-1波数范围内。结论:当归不同药用部位化学成分具有一定的差异。
Objective: To investigate the spectrum characteristics of near-infrared diffuse reflectance spectroscopy( NIR) fingerprint of different medicinal parts of Angelicae Sinensis Radix. Methods: 96 batches of samples were collected from 14 counties of Gansu Province and Yunnan Province. The NIR fingerprints were collected by integrated sphere. Similarity analysis and partial least square discriminant analysis( PLS-DA) were used to analyze the fingerprint. Results: The average spectrum of NIR fingerprint of different medicinal parts of Angelicae Sinensis Radix showed some differences; the absorbance in characteristic absorption was in a decreasing order of body tail head whole. Most NIR fingerprint similarities of different medicinal parts of Angelicae Sinensis Radix exceeded 0. 95. The established model of PLS-DA could be used to accurately classify the medicinal parts of Angelicae Sinensis Radix. The differences of NIR fingerprints of different medicinal parts of Angelicae Sinensis Radix were mainly existing in the wave number ranges of 8 443 - 8 284cm^- 1,7 003 - 6 896 cm^- 1,6 102 - 5 864 cm^- 1,4 847 - 4 674 cm^- 1,and 4 386 - 4 208 cm^- 1. Conclusion: The different medicinal parts of Angelicae Sinensis Radix have some differences in chemical components.
