摘要
目的:探讨凹叶景天叶的紫外—可见光谱定性鉴别特征,为凹叶景天进一步的开发和利用打下基础。方法:分别以水、95%乙醇、石油醚及乙酸乙酯为溶剂对凹叶景天叶进行紫外—可见光谱法鉴别。结果:凹叶景天叶各提取液的光谱特征吸收以石油醚、乙酸乙酯提取液的特征吸收峰较多、较强。结论:紫外—可见光谱鉴别法可作为凹叶景天叶的质量控制指标之一。
Objective The qualitative identification of UV - Visible spectra of Sedum emarginatum migo was studied, which laid the foundation for the further development and utilization of the leaves. Methods The leaves of Sedum emarginatum migo were identi- fied by ultraviolet -visible spectroscopy with water, 95% ethanol, petroleum ether and ethyl acetate as solvent. Results The spectral absorption of the extract of Sedum emarginatum Migo leaves was characterized by strong absorption of petroleum ether and ethyl acetate extract. Conclusion UV - Visible spectroscopy can be used as one of the quality control indexes of Sedum emarginatum Migo leaves.
