广西刘寄奴的紫外-可见光谱分析

Analysis of UV-Visible Spectra of Leaves of Herba Artemisiae Anomalae

以水、无水乙醇、石油醚及乙酸乙酯为溶剂分别进行回流提取、超声提取、浸渍提取,对提取液进行紫外—可见光谱法分析。四种溶剂提取液的紫外可见光谱均有特征,水提取液的紫外可见光谱特征吸收峰单一,无水乙醇、乙酸乙酯和石油醚各提取液的特征吸收峰较多;水提取液、无水乙醇各提取液吸收极强,乙酸乙酯、石油醚的提取液吸收较弱。本研究可为广西刘寄奴鉴别和成分分析提供辅助依据。

Qualitative identification methods for the Artemisia Lactiflora were established.Artemisia Lactiflora were identified by ultraviolet-visible spectroscopy with water,ethanol absolute,ethyl acetate and petroleum ether as solvent by reflux extraction,ultrasonic extraction and impregnation were carried out respectively.The characteristic absorption peaks of water were simplex.Ethanol absolute,ethyl acetate and petroleum ether were superior.The absorption of water and ethanol absolute were stronger than ethyl acetate and petroleum ether.This research found an auxiliary method to identify and component analysis Artemisia Lactiflora by the characteristic peak in UV-visible spectrum.
