Preparation of natural ferulaic acid

Abstract

The invention discloses a preparation method of natural ferulic acid, which comprises the steps as follows: after rice oil is expressed from rice bran, rice skin and rice germ or extracted from a solvent, the ferulic acid is extracted from a subsidiary product which is known as Blackfoot after the preparation of oryzanol in the rice oil. By the utilization of fatty acid salt as a dispersant, the crude product of the natural ferulic acid is prepared under the conditions of heating, pressurizing and stirring, and the pure product of the ferulic acid is prepared by centrifugal impurity removing, acid out and refining. The improved technology has low production costs, no lower alcohol used in the technology, the yield up to over 75 percent calculated in accordance with the content of the ferulic acid in the Blackfoot, and stable quality of products.

Description

technical field

[0001] The invention relates to a preparation method of natural ferulic acid. Background technique

[0002] Ferulic acid, Chinese chemical name: 3-methoxy-4-hydroxycinnamic acid, English name: Ferulic Acid, its chemical formula is: C 10 h 10 o 4 The structural formula is:

[0003]

[0004] Ferulic acid has increasingly wide applications in the fields of medicine, food, cosmetics, etc. The above-mentioned characteristics and other information about ferulic acid are listed in the patent application No. The extraction and purification process has been elaborated in detail. Natural plants such as Chuanxiong, Angelica, Gastrodia elata, and Jujube seed contain ferulic acid. Due to the low content of ferulic acid in natural plants, the extraction process is complicated, and the production cost is high. Its economic indicators are poor. In the known preparation or extraction and purification process of ferulic acid, black feet rich in crude fatty acids must fu...
