| 摘 要： | 通过采集浙江省5个浙贝母主产区不同生产基地的新鲜样品,获取浙贝母激光拉曼光谱的图谱,并进行特征峰分析和一阶导数分析。结果表明,浙贝母在875、912、965、1 153、1 312、1 410、1 482、1 598、1 641 cm-1等位移处出现9处明显的特征峰,并初步判定了这些特征峰的归属。研究结果表明,采用拉曼光谱进行农产品分析具有无损、快速、简便的特点,研究结果获取的9个特征峰可以作为鉴别浙贝母真伪、产地、溯源的手段。

| Abstract: | Fresh samples of Thunberg Fritillary Bulb from 5 main planting areas in Zhejiang Province were collected and the laser Raman spectroscopy was used to analyze and identify the samples. The results were used for the characteristic peak and first-order derivative analysis. The results showed that several characteristic strong peaks could be found at 875,912,965,1 153,1 312,1 410,1 482,1 598,1 641 cm-1 shift, and the affiliation of these peaks was identified. The results showed that Raman spectroscopic has the advantages of nondestructive, fast and simple, and the identified 9 peaks would be realized as the measures to distinguish the truth, origin area and traceability of Thunberg Fritillary Bulb. |
