研究了溶剂法(异丙醇和乙醇)提取辣椒红色素的的工艺，结果表明，异丙醇对辣椒红色素吸光度的影响程度从大到小依次为提取温度、提取次数、料液比、提取时间，其提取辣椒红色素的最佳工艺条件为:提取时间 2 h/次，料液比1 ∶ 15，提取温度40 ℃，提取次数3次；95%乙醇对辣椒红色素吸光度的影响程度从大到小依次为提取时间、提取温度、料液比、提取次数，其提取辣椒红色素的最佳工艺条件为:提取时间3 h/次，料液比1 ∶ 2，提取温度70 ℃，提取次数1次。

The organic solvent(isopropanol and ethanol compared)extraction technology of capsanthin is studied. The optimum conditions obtained by orthogonal tests are using isopropanol and ethanol as solvent. The result shows that the impact factors of capsanthin absorbance under isopropanol is extraction temperature＞extraction time>extraction times>solid to liquid ratio， and the best extraction conditions(A2B2C1D3) are found that the extraction time is every 2 hours， the ratio of solid to solution is 1∶15， the extraction temperature is 30 ℃ and the extraction time is every 3 hours； the impact factors of capsanthin absorbance under ethanol is extraction time>extraction temperature> solid to liquid ratio＞extraction times， and the best extraction conditions are found that the extraction time is 3h， the ratio of solid to solution is 1∶2， the extraction temperature is 70 ℃ and the extraction time is 1.
