Problems solved by technology

This method requires high equipment, and it is difficult to separate fatty acids with similar molecular weights to linolenic acid, which has certain limitations in application.
[0009] So far, there is no relevant report about the separation of α-linolenic acid from linseed oil by β-cyclodextrin inclusion method

Embodiment 1

[0020] Materials and instruments: Flaxseed, purchased from Hohhot Agricultural Products Market, was identified as the seed of Linum usitatissimum by the teachers of Inner Mongolia University. Flaxseeds were crushed and passed through an 80-mesh sieve; β-cyclodextrin was purchased from Beijing Aoboxing Biotechnology Co., Ltd., analytically pure; petroleum ether and absolute ethanol were purchased from Guangzhou Huaxin Instrument Co., Ltd., analytically pure.

[0021] Constant temperature magnetic stirrer, constant temperature water bath, electric heating constant temperature blast drying oven Shanghai Botai Experimental Equipment Co., Ltd.; Soxhlet extraction device Guangzhou Huaxin Instrument Co., Ltd.

[0022] Preparation of linseed oil: Weigh 20g of linseed, crush it and put it into a filter paper bag, put the filter paper bag in a Soxhlet extractor, add petroleum ether to 2 / 3 of the flat-bottomed flask, and place the Soxhlet extraction device at 45°C In the constant tempera...

Abstract

The invention discloses a method for extracting purified alpha-linolenic acid from linseed oil. The method disclosed by the invention comprises the following steps of: smashing and sieving flaxseeds; extracting to obtain linseed oil mixed fatty acid; mixing absolute ethanol with beta-cyclodextrin according to a certain proportion to form an inclusion compound; and performing inclusion at a specific temperature for a certain period of time to obtain fatty acid which is rich in alpha-linolenic acid. The method is simple, convenient and practicable, has the advantages of high yield, low cost and the like, and has good industrial prospect.

Description

technical field [0001] The invention relates to the field of pharmacy, in particular to a new method for extracting and purifying alpha-linolenic acid from linseed oil. Background technique [0002] Cardiovascular and cerebrovascular diseases are the "first killer" of human health, with the characteristics of "three highs and one low" of high disability rate, high morbidity rate, high mortality rate and low prevention rate. At present, about 180 million people in my country suffer from cardiovascular and cerebrovascular diseases; 60 million people suffer from coronary heart disease; 70 million people suffer from cerebral infarction or cerebral hemorrhage; Among them, about 57% of people suffer from various degrees of cardiovascular and cerebrovascular diseases; the incidence of arteriosclerosis in people over 50 years old is 79.9%; the incidence of arteriosclerosis in people over 70 years old is almost 100%; The number of deaths was as high as 3 million, accounting for 37.63%...
