Problems solved by technology

[0003] At present, the extraction method of the active ingredients of coix seed is usually the traditional water extraction method. In order to improve the extraction efficiency, relevant researchers have proposed a variety of auxiliary methods on the basis of the water extraction method, such as enzyme-assisted method, ultrasonic-assisted water extraction method, Microwave-assisted, ethanol-water extraction, but the effect of these auxiliary methods on improving the extraction rate is still not obvious

comparative example 1

[0022] A method for extracting coix seed active substances with a two-component auxiliary agent, comprising the following steps:

[0023] 1. Use a pulverizer to pulverize the coix seed, pass through a 40-mesh sieve, dry, and keep the weight constant.

[0024] 2. Accurately weigh 10g of coix seed powder and place it in a three-necked flask, add 50mL of pure water to obtain an extract, stir to mix the raw materials evenly, heat and reflux at 80°C for 120min, and the extraction is complete.

[0025] 3. Afterwards, the extract was separated by centrifugation (10000r / min, 15min), the supernatant and the oil phase were collected, dried in an oven, weighed and calculated to yield 3.8% of the active substance of coix seed, as figure 1 shown.

[0032] A method for extracting coix seed active substances with a two-component auxiliary agent, comprising the following steps:

[0033] 1. Use a pulverizer to pulverize coix seed, pass through a 40-mesh sieve, dry, and keep the weight constant.

[0034] 2. Accurately weigh 10g of coix seed powder and place it in a three-necked flask, add 50mL of purified water, add 0.01g of betaine (accounting for 0.1% of the weight of coix seed powder), stir to mix the raw materials evenly, heat and reflux at 80°C for 120min, and the extraction is complete.

[0035] 3. Afterwards, the extract was separated by centrifugation (10000r / min, 15min), the supernatant and the oil phase were collected, dried in an oven, weighed and calculated to yield 3.9% of the active substance of coix seed, as figure 1 shown.

Abstract

The invention relates to a two-component additive extraction method for active substances of coix seeds, and the extraction method specifically comprises the following steps: mixing coix seed powder with water and a two-component additive to obtain a leaching solution, then leaching the leaching solution to finally obtain the active substances of coix seeds, wherein the two-component additive comprises an amino-containing additive A and an alcohol additive B. Compared with the prior art, the method has the advantages that the extraction efficiency of active substances of coix seeds is improved, the added two-component additive is conventional cosmetic raw materials, the dosage is small, the content in a finished product is small, separation is not needed, and extracted solid can be directly used for cosmetic production.

Description

technical field [0001] The invention relates to the technical field of extraction of biologically active substances, in particular to a method for extracting coix seed active substances with two-component additives. Background technique [0002] Coix seed, as a traditional medicinal and edible plant in my country, has rich nutritional and medicinal value, such as diuretic and penetrating dampness, invigorating the spleen and stopping diarrhea, removing numbness, draining pus, detoxifying and dispelling stagnation, and can be used to treat edema, Beriberi, dysuria, spleen deficiency and diarrhea, arthralgia due to dampness, lung abscess, intestinal abscess, warts, cancer and other diseases. 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 substances, mainly including coixene, triglycerides, fatty acids, lactams, Coix seed lactone, sugars, sterols, p...
