松萝酸制备工艺的研究

Reserch the Preparatory Technology of Usnic Acid

目的:探讨松萝酸提取工艺新方法及进行检测鉴定。方法:采用热乙醇回流提取法,离心分离得到松萝酸、蒸发皿蒸干,收集后为纯品。用紫外UV-2204型光谱仪、熔点测定仪进行定性分析,用高效液相色谱仪对纯度进行测定。结果:从植物松萝中提取松萝酸纯度达到99.87%,熔点、紫外吸收光谱分析与标准品相一致。结论:该提取工艺简单,成本低,适合规模化生产,对环境无污染,有利于松萝酸的开发利用。

Objective：Porbe into a new technological method of Abstract Usnic Acid and analysis and identification method.Method：Use an Abstract method by heat Alcohol regurgitation,make centrifugation and separation to gain Usnic Acid,then evaporate by an evaporating dish,form the pure quality,use an UV-2204 type ultraviolate spectrometer and a king of fusion-pointmeter to make the qualitive analysis and measure the purified quality by a liquid phase Chromatograph.Result：Usnea could achieve 99.87%,fusion point and ultravionlat absorption spectrum analysis agree to the standard samples.Conclusion：this Abstracted technological scale.Conclusion：This Abstracted technological method is very simple,its cost is low,suits to bigger scale production,no environment pollution,profits to develpoe and use Usnic Acid.
