Embodiment Construction

[0013] The specific implementation steps of extracting gamma-linolenic acid are as follows:

[0014] 1. Raw material preparation: Harvest bloom cyanobacteria from eutrophic water body, concentrate, dehydrate, dry, and pulverize to obtain cyanobacteria powder.

[0015] 2. Preparation of GLA mixed ester: Add 2 liters of petroleum ether solvent to 2Kg of cyanobacteria powder, freeze and soak for 120 minutes, use an ultrasonic instrument to break the cells for 9-10 minutes, and continue soaking overnight. Reflux in a water bath at 60°C for 90-120 minutes, remove algae cell residues by suction filtration, and obtain about 1.5 liters of γ-linolenic acid mixed ester.

[0016] 3. Saponification of gamma-linolenic acid mixed esters: add 2 times the volume of saponification liquid to gamma-linolenic acid mixed esters, add 3 liters of saponification liquid in 1.5 liters of gamma-linolenic acid mixed esters [potassium hydroxide: ethanol: water = 2:15:5], mix well, saponify in a 60°C wate...

Abstract

The invented prodn. process contains steps of: (1) raw material algal bloom blue green algare is concentrated, dewatered, dried and crushed to obtain algare powder; (2). said powder is soaked in mineral ether at room temp. to break the cells, and continuously soaked after a night, refluxing in water bath, then removing leavings of the cell to obtain gamma-linoleates mixed ester; (3). said ester is saponified after adding saponifier in water bath, then cooled to room temp., (4). adjusting said solution pH value to 3-4, then methoxycarbonylation and urea packing reaction to abtain gamma-linoleic acid. Advantages are: simple process, high obtg. rate, easy to obtain raw material, with social, environment and economic benefits.

Description

technical field [0001] The invention relates to extracting gamma-linolenic acid from cyanobacteria, more specifically a method for extracting γ-linolenic acid from cyanobacteria, which is suitable for medical treatment, health care and other industries. Background technique [0002] In recent years, due to the rapid development of industry, the rapid increase of population, the aggravation of urbanization, and the severe environmental pollution, the degree of eutrophication in many water bodies in my country has intensified, causing a large number of algae, especially blue-green algae, and some water bodies even have serious blue-green algal blooms. Hua, directly affects the quality and availability of water bodies, and endangers the health of livestock and human beings. A large number of cyanobacteria blooms in lakes in the middle and lower reaches of the Yangtze River occurred from April to October, especially in the high temperature season from ...
