AI Technical Summary

Problems solved by technology

Five years ago, there were thirteen manufacturers with quasi-brand names across the country. The main raw material for the production of evening primrose gum oil was evening primrose, which is a wild plant. The main production areas were Henan and Northeast China. There is a small amount of artificial cultivation, but due to many years of competing for raw materials, the resources have decreased year by year, resulting in thirteen manufacturers having to switch production due to lack of raw materials, and the remaining three are also in an annual crisis due to the shortage of raw materials. The dilemma of an average production of less than five months
Due to the low production in China, it is only used for medical purposes at present, and there has been a supply crisis, let alone blending with edible oil and applying it to health food

Embodiment 1

[0021] The pure natural wild plant Pine massoniana distributed in my country's Changbai Mountains, Daxing'an Mountains and Xiaoxing'an Mountains is used as raw material. It is dried at 135°C, air-selected to remove impurities, squeezed to filter the juice, and the filtrate is dewaxed at -4°C. The filtrate is decolorized with clay with 10% weight of the filtrate, and then deodorized, dehydrated, heated and balanced, and the obtained product is an extract rich in γ-linolenic acid.

Embodiment 2

[0023] Except that the raw material adopts masson pine produced in Russia, and the drying temperature is 150° C., other processes are the same as in embodiment 1.

Embodiment 3

[0025] The wild plant Pine masson in Yunnan is used as raw material, dried at 145°C, air-selected to remove impurities, squeezed to extract juice and filtered; dewaxed at -5°C, decolorized by adding white clay accounting for 12% of the entire filtrate weight; deodorized at 110°C , Dehydration for 18 minutes; heated and balanced at 60°C for 1.5 hours, that is the extract rich in γ-linolenic acid.

Abstract

The extract with rice gamma-linoleic acid is prepared with Pinus massoniana as raw material and through the steps of drying, eliminating impurity, squeezing to obtain juice, dewaxing of the filtrate at minus 3 to minus 6 deg.c, decoloring with clay in 8-12 wt% of filtrate, deodorizing, dewatering and heating to homogenize. The produce has very high gamma-linolenic acid content.

Description

technical field [0001] The invention relates to an extract containing gamma-linolenic acid, and also relates to a preparation method of the extract. Background technique [0002] γ-linolenic acid (γ-linoleic acid) molecular formula C 18 h 32 o 2 , the chemical structure is octadecatriene p-methyl ester, which is generally called unsaturated fatty acid. The international standard for biological bond arrangement is Octadeca-6, 9, 12-teienoic acid, which is composed of three enoic acids with 18 carbon atoms. It is a rare and rare substance in biological bonds. Γ-linolenic acid is an essential fatty acid to maintain the normal function of the human body. It can be metabolized in the body to form dihomo-linolenic acid (DGLA) or arachidonic acid (AA) and then converted into prostaglandin (PG s ) and leukotrienes (LT). [0003] A large number of studies and experiments have proved that γ-linolenic acid has a wide range of pharmacological effects. It has antibacterial, anti-tum...
