基于太赫兹时域光谱的硫熏白芷快速鉴别研究
|
Abstract:
本研究以2024年川白芷为样本，运用太赫兹时域光谱技术(THz-TDS)，对川白芷是否使用硫熏工艺进行快速鉴别。传统的鉴别手段如通过形态学、显微特征、理化性质及多光谱分析，均无法快速区分硫熏川白芷。利用太赫兹技术对中药成分变化的敏感性，可快速并准确区分硫熏川白芷。该研究成果为构建基于太赫兹技术的白芷快速质量评价标准提供了依据，为中药质量控制检验技术提供了新方法。
In this study, taking Chuan-Angelica dahurica harvested in 2024 as research samples, Terahertz Time-Domain Spectroscopy (THz-TDS) was employed for the rapid identification of Chuan-Angelica dahurica subjected to sulfur-fumigation processing. Conventional identification methods, including morphological observation, microscopic characterization, physicochemical property analysis, and multi-spectral detection, are incapable of rapidly distinguishing sulfur-fumigated Chuan-Angelica dahurica from non-fumigated counterparts. By virtue of its high sensitivity to changes in the chemical components of Traditional Chinese Medicines (TCMs), THz-TDS enables the rapid and accurate differentiation of sulfur-fumigated Chuan-Angelica dahurica. This research finding lays a foundation for establishing a rapid quality evaluation standard for Chuan-Angelica dahurica based on THz technology and provides a novel approach for the quality control and inspection of TCMs.
