摘要
研究了采用乙醇提取法从紫苏中提取迷迭香酸的工艺条件。方法采用正交实验L9(34)优化迷迭香酸乙醇浸提法的提取工艺,硫酸亚铁比色法测定迷迭香酸含量。确定了最佳工艺条件为:50%乙醇为提取剂,料液比为1:50(w/v),提取温度为65℃,提取时间为35min,迷迭香酸提取率为1.061%比热水浸提法提高了30.18%。
The extraction of rosmarinic acid from Folium Perillae by ethanol extraction process and the optimal extracting technological conditions were studied. We optimized the extraction factors with L9(3^4) orthogonal experimental design, and the quantitative analysis with FeSO4 method. The results showed that the optimal extracting technological conditions were as follows: extraction solvent was 50 % alcohol,the mass ration of material to liquor was 1 : 50 (w/v),extracting temperation was 65℃ and extracting time was 35 min. Under this condition, the extracting rate of rosmarinic acid could reach 1.061% .The extraction rate of rosmarinic acid by this method was higher than that by hot water soaking about 30.18 %.
