温度对艾草不同部位药性影响的太赫兹光谱分析

Study on Medicinal Components of Artemisia Argyi Based on Terahertz Time-Domain Spectroscopy

艾草具有抑菌、抗虫、抗病毒等巨大的应用价值,同一株艾草的入药部位不同,药性是有差异的。不同的加热温度也一定程度上影响中药成分的提取,稍不注意就会严重影响中草药的实际药效。太赫兹时域光谱技术作为未来无损检测的新型技术,成为近年来药物检测领域的研究热点。本文以河南省驻马店市泌阳县地区艾草为研究对象,利用自行搭建的太赫兹时域光谱系统,测量了艾草不同部位和不同烹煮温度下的太赫兹光谱。利用相关模型提取了艾草的太赫兹频谱、透射率和吸收系数等参数,以此分析艾草药性。本工作为艾草在生活中的具体应用方法奠定数据基础,促进艾草从传统用法到科学用法的转变。

Artemisia argyi has great application value benefits from the excellent features such as antibacterial,insect resistance,antiviral and so on.Different parts of the artemisia argyi always exhibit distinct medicinal properties.The heating temperature also affects the extraction of the medicinal components in artemisia argyi to a certain extent.A little mistake will seriously affect the actual effectiveness of Chinese herbs.Terahertz time-domain spectroscopy(THz-TDS)is a non-destructive testing technology.It has become a research hotspot in the drug detection field in recent several years.In this paper,the artemisia argyi from Biyang county,Zhumadian,Henan is obtained as research object.The terahertz spectra of the artemisia argyi for the different parts and cooking temperatures including the stem,root,and leaf are investigated.The terahertz frequency spectra,transmittance,and absorption coefficient are extracted,and then explore the medicinal properties.This work provides database support for the using of the artemisia argyi in people’s life,promotes the transition from traditional method to scientific method.
