采用单因素和正交试验,考察提取溶剂、提取时间、提取温度、料液比、提取次数等因素对白莲花粉β-胡萝卜素提取的影响.结果显示:白莲花粉β-胡萝卜素的最佳提取条件为:乙酸乙酯作为有机提取溶剂,按提取时间180min、45℃、料液比1:6,提取2次,β-胡萝卜素提取率达679.864μ/g.%To optimize the process conditions for the solvent extraction of 3-Carotene from white lotus pollen, the effects of solvent type, extraction duration and temperature, and material/liquid ratio, extraction times on factors were studied by single factor and orthogonal array design experiments. The optimal extraction process for (3 -Carotene from white lotus pollen was found to be as follows:the solvent type of ethyl acetate, the extraction time of 180min, the extraction temperature of 45cC,the material/liquid ratio of l:6,the extraction times of 2, and the yield of P-Carotene from white lotus pollen can achieve 679.864(xg/g.
