中文摘要:

研究不同大孔吸附树脂对薰衣草中迷迭香酸静态吸附与解吸特性，筛选出一种吸附及解吸效果良好的树脂LX-60，其静态吸附量与解吸量分别达到5.12 mg/g和4.86 mg/g。对LX-60进行吸附和解析条件考察，最终得到纯度为15.6%的迷迭香酸产品，其得率为86.79%。比纯化前的迷迭香酸质量浓度0.37%提高了42倍。本研究表明，利用大孔吸附树脂能够纯化薰衣草中的迷迭香酸，为通过薰衣草提取分离来生产迷迭香酸提供理论和实验基础。

英文摘要:

Static adsorption and desorption of characteristics of different macroporous adsorption resin was studied，LX-60 has a good effect to adsorb and desorb. The static adsorption and desorption of quantity was 5.12 mg/g and 4.86 mg/g. And adsorption and desorption of condition was investigated for LX-60，products of rosemary acid was got in the end，purity was 15.6% and yield was 86.79%. The purity of rosemary acid was 42 times higher than the purity of 0.37%. This study indicated it was feasible to purify rosemary acid in the lavender，as well as this research provided theory and experimental basis for production.
