摘要：
This invention involves a method for preparing high-contentconjugated linoleic acid (CLA) products with common vegetable oil. This invention includes alcoholysis, purification and isomerization of vegetable oil. Alcoholysis is for preparing correspondingmethyl ester or ethyl ester with glyceride; purification of methyl ester or ethyl ester is for obtaining methyl linoleate or ethyl linoleate of content over 85% through silver-basedsilicagel columnchromatography; high-content CLA is obtained after alkali-catalyzed conjugation of methyl linoleate or ethyl linoleate, and CLA products are prepared as needed. This invention changes the status quo of preparing high-content CLA with safflower oil alone, expands sources of CLA, and develops an efficient technology for separation and purification of linoleic acid. The CLA obtained is of high purity and meets applications in pharmaceutical, health care products and other industries.
