芦笋老茎中芦丁的提取工艺

Technology of Extracting Rutin from the Old Stalk of Asparagus

采用正交试验方法,对芦笋老茎中芦丁的最佳提取工艺进行了研究。结果表明:热水提取芦丁的最佳工艺条件为,加水量为原料质量的10倍,提取温度为70℃,时间2.5 h;用乙醇水溶液提取芦丁,体积分数为70%的乙醇溶液用量为原料质量的25倍,提取温度70℃,时间3 h。

The optimum extraction conditions of rutin from asparagus were investigated by using orthogonal design. The results showed that the optimal conditions using hot water extracting were： the ration of water to asparagus 1：10, the extracting temperature 70℃, and the extracting time 2.5 hours, while the best conditions by using alcohol extracting were： the ratio of 70% aqueous alcohol to flesh of asparagus 1：25, the extracting temperature 70℃, and the extracting time 3 hours.
