摘要：极性和非极性混合溶剂一步提取法是迷迭香抗氧化剂和精油综合提取的有效方法，操作简单，容易实施。迷迭香抗氧化剂和精油一步综合提取的合理条件为：混合溶剂石油醚-乙醇-水的体积比80：15：5，其用量为迷迭香叶质量的10倍，80℃提取3h。迷迭香精油的得率在2％-3％，主要含有α-蒎烯、1，8-桉叶素、莰烯、樟脑、马鞭草烯酮、龙脑、4-松油醇、芋烯和乙酸龙脑酯等成分。迷迭香抗氧化剂的得率为16．98％，主要含有鼠尾草酸、鼠尾草酚和迷迭香酸等活性成分，其量分别为15．17％、2．51％和5．62％。
One-step extraction with polar and nonpolar mixed solvents was a method of effective comprehensive extraction for antioxidant and essential oil of rosemary （Rosmarinus officinalis L. ）. The method was simple on operation and was easily put into practice. The reasonable conditions of comprehensive extraction for antioxidant and essential oil of rosemary were petroleum ether- ethanol-water of volume fraction 80：15 ： 5 as mixed solvent, 10 folds of mass fraction of mixed solvent to rosemary leaves, 3 h for extraction at 80 ℃. The yield of rosemary oil was 2 %-3 %. The constituent analysis of rosemary oil showed that the essential oil mainly contains α-pinene, 1,8-cineole, camphene, camphor, verbenone, borneol, terpinen-4-ol, limonene, and bornyl acetate. The average yield of rosemary antioxidant was 16.98 %. The main active components of rosemary antioxidant were carnosic acid, earnosol, and rosmarinic acid, whose contents were 15.17 % , 2.51% and 5.62 % , respectively.
