红枣芦丁提取工艺的研究

Technology of extracting rutin from Zizyphus jujube

研究了从红枣中提取芦丁的工艺条件.实验结果表明,用热水提取芦丁,加水量为原料重量的17倍,提取温度为70℃,时间60min;用乙醇提取芦丁,75%的乙醇溶液的用量为原料重量的16倍,提取温度75℃,时间120min.

Zizyphus jujube is rich in rutin. The technological conditions of extracting rutin from Zizpyhus jujube are studied. The results show that the optimal extracting conditions using water is the adding ration of water to flesh of Zizyphus jujube 17∶1, the extracting temperature 70℃ and the time 60 min; the condition using aqueous alcohol is the adding ratio of 75% aqueous alcohol to flesh of Zizyphus jujube 16∶1, the extracting temperature 75℃ and the time 120 min.
