Problems solved by technology

This process adopts the solvent method, which consumes a lot of organic solvents, and the production process of the product is easy to produce new environmental pollution. The cost is high and there are inevitably solvent residues. The operation is troublesome and the workload is heavy, so it is not suitable for large-scale production.

Embodiment Construction

[0013] The technological process that each embodiment extracts high-purity sesamin from sesame oil is as follows: 100 grams of sesame oil are packed the chromatographic column of the chromatographic adsorbent described in the following each embodiment through sherwood oil, simultaneously with pure sherwood oil (boiling range 60-90℃) the eluent passes through the chromatographic column to elute oily impurities other than sesamin, and the eluate effluent is shaken with 36% concentrated hydrochloric acid and 2% furfural aqueous solvent solution, and the water phase can be stopped when it appears dark red Elution, at this time, there are three color bands in the upper, middle and lower parts of the column; the upper part is a variegated band, the middle is a yellow band, and the lower part is an oil layer color band; then take out the adsorbent band layer in the middle of the chromatography column and place it in a heat reflux container In, utilize the 95% (v / v) medical alcohol tha...

Abstract

The present invention discloses an extraction process of sesamin. Said process includes: firstly, purification process of sesamin: making sesame oil pass through the cylindrical body container whose interior is filled up with chromatographic adsorbent, at the same time making fat-soluble eluent, pass through the cylindrical body container to elute oily impurity, eluting until the bottom layer colour band of the cylindrical body container is removed; them making extraction process of sesamin: collecting adsorbent color band layer positioned in middle portion of the cylindrical body container, and utilizing solvent capable of dissolving sesamin to extract extract of sesamin containing in the color band layer. Said invention has the advantages of high extraction rate and high purity.

Description

Technical field: [0001] The technical scheme to be protected by the present invention belongs to the technical field of sesamin extraction technology. technical background: [0002] Sesamin is an all-natural ingredient hidden in sesame seeds with the molecular formula C 20 h 18 o 6 , with a melting point of 122-123°C, and its specific rotation [a] D 20 It is +64.5°C (chloroform). It has a double tetrahydrofuran ring structure, white crystal, insoluble in water, easily soluble in chloroform, ethyl acetate, soluble in hot ether, hot ethanol and other solvents. Sesamin seeds contain about 0.3-0.5% by weight of sesamin. Sesamin oil contains about 0.5-1.0% by weight of sesamin. In addition to sesame seeds, asarum, Wujiapi, paulownia, ginkgo, and longan all contain sesamin. Through research and experiments, it has been found that sesamin has anti-hypertensive and cardiovascular hypertrophy, liver protection, anti-oxidation, Lowering cholesterol, preventing arteriosclerosis...
