Embodiment 1

[0023] A method for extracting coix seed oil, comprising the steps of:

[0024] (a) After drying coix seed, it is pulverized by an ultrafine pulverizer to obtain ultrafine powder;

[0025] (b) Extract the superfine powder by boiling and refluxing under reduced pressure for 5 hours, boil the water at 60°C under reduced pressure, and then filter to obtain the aqueous solution and pretreated raw materials;

[0026] (c) Pass the pretreated raw material through the supercritical carbon dioxide extraction process. The supercritical carbon dioxide extraction process includes the following steps: put the pretreated raw material into the extraction kettle, and pass supercritical CO2 under the conditions of 40°C and 20Mpa 2 For extraction, supercritical CO 2 The flow rate is controlled at 500kg / h; after the extraction is completed, the supercritical CO 2 Put the crude coix seed oil into the separator to separate and obtain the crude coix seed oil, the separation pressure is 10Mpa, and...

Embodiment 2

[0032] A method for extracting coix seed oil, comprising the steps of:

[0033] (a) After drying coix seed, it is pulverized by an ultrafine pulverizer to obtain ultrafine powder;

[0034] (b) Soak the superfine powder in water for 1 hour, and then carry out decompression boiling and reflux extraction for 10 hours, depressurize to make the water boil at 50°C, and then filter to obtain the aqueous solution and pretreated raw materials;

[0035] (c) Pass the pretreated raw material through the supercritical carbon dioxide extraction process. The supercritical carbon dioxide extraction process includes the following steps: put the pretreated raw material into the extraction kettle, and pass supercritical CO2 under the conditions of 50°C and 18Mpa 2 For extraction, supercritical CO 2 The flow rate is controlled at 350kg / h; after the extraction is completed, the supercritical CO 2 The crude coix seed oil is separated by passing through the separator, the separation pressure is 9M...

Embodiment 3

[0041] A method for extracting coix seed oil, comprising the steps of:

[0042] (a) After drying coix seed, it is pulverized by an ultrafine pulverizer to obtain ultrafine powder;

[0043] (b) Soak the superfine powder in water for 2 hours, and then carry out decompression boiling and reflux extraction for 7.5 hours, reduce the pressure to make the water boil at 40°C, and then filter to obtain the aqueous solution and pretreated raw materials;

[0044] (c) Wash and dry the pretreated raw materials before proceeding to the supercritical carbon dioxide extraction process. The supercritical carbon dioxide extraction process includes the following steps: put the pretreated raw materials into the extraction kettle, and pass the supercritical Critical CO 2 For extraction, supercritical CO 2 The flow rate is controlled at 200kg / h; after the extraction is completed, the supercritical CO 2The crude coix seed oil is separated by passing through the separator, the separation pressure ...

Abstract

The invention discloses an extraction method of coix seed oil, which comprises the following steps: (a) drying coix seeds, and crushing the dried coix seeds by an ultrafine grinder to obtain ultrafinepowder; (b) performing reduced-pressure water boiling reflux extraction on the ultrafine powder for 5-10 hours, reducing the pressure to boil water at 40-60 DEG C, and then conducting filtering to obtain an aqueous solution and a pretreated raw material; and (c) carrying out supercritical carbon dioxide extraction on the pretreated raw material to obtain the coix seed oil. The obtained coix seedoil is low in impurity content and easy to purify.

Description

technical field [0001] The invention relates to the technical field of coix seed oil extraction, in particular to a method for extracting coix seed oil. Background technique [0002] Coix seed is a plant of the grass family Coix Coix lacryma-jobi L. dry ripe seed kernels. Inducing water to penetrate dampness, invigorating the spleen and stopping diarrhea, removing numbness, draining pus, detoxifying and dissipating stagnation. For edema, beriberi, dysuria, spleen deficiency diarrhea, arthralgia due to dampness, lung abscess, intestinal abscess, warts, cancer. Modern studies have found that coix seed has pharmacological effects such as analgesia, anti-inflammation, immune regulation, anti-ulcer, lowering blood fat and weight loss. In recent years, scholars at home and abroad have studied the chemical components of coix seed by TLC, HPLC, GC and other methods, and found that it contains a variety of active components, mainly including coixenolide, triglycerides, fatty acids...
