Embodiment 1

[0018] Preparation of Yuanbao maple hair oil, made by the following method:

[0019] (1) Yuanbao maple samara enters the primary cleaning screen for preliminary cleaning, and removes impurities with a stone removal machine, then passes through a magnetic separator, and finally sends it to the pod removal host to remove pods, and then obtains the removed pods of Yuanbao maple after passing through the re-selection machine seed;

[0020] Yuanbao maple seeds are screened in multiple stages and classified to remove impurities. After classification, the graded Yuanbao maple seeds enter the shelling process, and the shells are obtained from Yuanbao maple kernels. Sorting machine to select residual shells, unhulled Yuanbao maple kernels, and moldy grains;

[0021] (2) Carry out moist heat treatment on the maple seed kernels of Yuanbao, adjust the moisture content to 8-10%, press with a shaft-cooled screw cold press, the pressing temperature is not higher than 65°C, and the residual ...

Embodiment 2

[0023] The method for extracting nervous acid from Yuanbao maple oil comprises the following steps:

[0024] (1) Filter Yuanbao maple oil to remove impurities; then wash Yuanbao maple oil with water; perform deacidification treatment, then heat and reflux in a water bath at 80°C for 4 hours, wash with saturated aqueous sodium chloride solution and reflux for 2 hours, until Until the ingot maple oil is clarified, let it stand at room temperature for 4 hours, separate the liquid and keep the supernatant, and then wash the supernatant with saturated sodium chloride aqueous solution for at least 2 times;

[0025] For the deacidification treatment, according to the acid value of maple ingot oil, add 0.65% sodium hydroxide solution of maple ingot oil weight for deacidification treatment, the concentration of sodium hydroxide solution is 4%, the reaction condition is 45 ℃, and the stirring speed is 60r / min, and the time is 30min. After the reaction is completed, the temperature is r...

Abstract

The invention relates to the technical field of medicinal plant ingredient extraction and especially relates to a method for extracting nervonic acid from acer truncatum oil. The method comprises thefollowing steps: removing impurities from crude acer truncatum oil; performing deacidification treatment, performing transesterification on acer truncatum oil and extracting with petroleum ether; taking blended fatty acid; mixing the blended fatty acid with urea and ethyl alcohol in volume concentration of 95%, thereby acquiring a urea-coated mixed solution; refrigerating and freezing; drying under low temperature, thereby acquiring a crude product of nervonic acid; separating by silica gel column chromatography and repeatedly freezing, crystalizing and purifying, thereby acquiring a pure product of nervonic acid. According to the method for extracting nervonic acid from acer truncatum oil provided by the invention, acer truncatum oil is taken as a raw material; the content of nervonic acid in acer truncatum oil is as high as 5.5%; the extraction raw material is extensive in source and low in cost; compared with deep sea shark oil, acer truncatum oil is a new sustainable utilizable nervonic acid resource; the extraction method provided by the invention is simple in operation, high in extraction rate and suitable for industrial production.

Description

technical field [0001] The invention relates to the technical field of extraction of medicinal plant components, in particular to a method for extracting nervonic acid from ingot maple oil. Background technique [0002] Nervoic acid is a long-chain unsaturated fatty acid, also known as sharkic acid because it is mainly derived from deep-sea sharks and shark oil. The chemical name is cis-15-tetradecenoic acid, and the molecular formula is C 24 h 46 o 2 , molecular weight 366.6, white powdery solid. Nervous acid was first discovered in the nervous tissue of mammals, and its content is relatively high in nervous tissue and brain tissue. It also exists in the retina and semen. It is an important part of biological membranes and usually exists in the formation of glycosphingolipids and sphingomyelin In white fat of the brain, it is a marker of medulla in cerebrosides. The route of chemical synthesis of nervonic acid has complicated process and low yield, so it cannot be indu...
