摘要
采用水蒸气蒸馏法对艾蒿精油的提取工艺进行了研究,在单因素的基础上,通过正交试验得出最佳工艺参数:蒸馏时间1.5h、料液比为10∶1、浸泡时间1h,在此条件下精油得率为0.25%,各因素对提取结果影响的程度依次为:蒸馏时间>料液比>浸泡时间。采用水蒸气蒸馏法得到的艾蒿精油为浅绿色液体,有较浓的清香味,可用于食品、医疗、生物防治、果蔬保鲜等领域,是天然香料的一种原料来源。
This paper studies the extraction of essential oil from A rtemisia argyi by steam distil‐lation .The optimum extraction technological conditions according to orthogonal tests are as fol‐lows ：steam distilling for 1 .5h ,adding 10 times water ,dipping for 1h .The order of influencing significance of the parameters tested is ：distilling time〉 water‐leaves rations〉 dipping time .The essential oil extracted by steam distillation is light green liquid with A rtemisia argyi ,which would be a good spice for perfume in food ,medical ,biological control ,vegetable and fruit preser‐vation ect .and would be a new resource of natural fragrance and flavor .
