Production technology for acquiring two antioxidant agents from Rosmarinus officinalis L.

The invention discloses a production technology employing a ultrasonic countercurrent extraction process and a membrane separation (molecular sieve) process to acquire two antioxidants from Rosmarinus officinalis L. The production technology comprises adding 30 to 85% of edible alcohol into fresh rosemary branches and leaves, carrying out a ultrasonic counter current extraction process for a mixture of the edible alcohol and the fresh rosemary branches and leaves to obtain an extracted liquid with a solid-to-liquid ratio of from 1:10 to 1:30, and carrying out a membrane separation (molecular sieve) process to separate two antioxidant agents consisting of a rosemary fat-soluble antioxidant agent (comprising carnosic acid as a representative) and a rosemary water-soluble antioxidant agent (comprising rosmarinic acid as a representative) from the extracted liquid, wherein a heating time of the extracted liquid can be reduced through the membrane separation (molecular sieve) process thus a conversion ratio of rosmarinic acid to carnosol is reduced. A content of carnosic acid in the rosemary fat-soluble antioxidant agent is increased through a CO2 supercritical extraction process. The rosemary water-soluble antioxidant agent (comprising rosmarinic acid as a representative) is separated from a liquid obtained through a concentration process under reduced pressure and a solid-liquid separation process, and a content of rosmarinic acid in the rosemary water-soluble antioxidant agent is increased through recrystallization from ethanol. The production technology has the advantages of simple processes, low energy consumption, high production efficiency, production safety, and no harmful residual solvent due to single edible alcohol usage during all production processes.
