Abstract

The invention discloses an amyrin cinnamate extract and a preparation method thereof. The amyrin cinnamate extract is prepared from gymnema sylvestre fruit. The preparation method of the amyrin cinnamate extract comprises the following specific steps of (1) preparation of extract; (2) preparation of extract in all positions; (3) obtaining of the amyrin cinnamate extract: taking the extract in the position of petroleum ether, separating by using silica gel column chromatography, carrying out gradient elution by using petroleum ether-ethyl acetate as an eluting agent, obtaining a yellow oily matter in a 40 to 1 eluting part, and at least repeatedly carrying out four times of recrystallization by using acetone after washing off the yellow oily matter from a solution by using the petroleum ether, thus obtaining white feather-like crystals, i.e., a compound-the amyrin cinnamate extract. According to the amyrin cinnamate extract and the preparation method of the amyrin cinnamate extract, disclosed by the invention, the ingredient of amyrin cinnamate is extracted from the gymnema sylvestre fruit for the first time, the preparation method is simple and easy to operate, and the obtained total extract yield is up to 12.18 percent to 12.93 percent.
