Embodiment 1

[0063] The method for extracting ginsenosides comprises the following steps in turn:

[0064] (1) Pre-treatment: put American ginseng roots in an oven at 70-80°C to dry for 0.3-0.5h, crush and sieve,

[0065] (2) Microwave extraction: use 40%-50% ethanol and 40%-50% n-butanol as the extraction solvent to extract ginseng by microwave extraction method, and extract 2-4 times; each dosage of ethanol is ginseng 3-7 times the weight; the amount of n-butanol is 1-2 times the weight of ginseng; glucose with a concentration of 3-6g / 100ml is added to the extraction solution for extraction, and the amount of n-butanol is 1-2 times the weight of ginseng; after microwave extraction Obtain the crude extract of ginseng total saponins, the power of microwave extraction is 700W-800W, and the time of microwave extraction is 5-10min; the amount of ethanol and n-butanol is in milliliters, and the weight of ginseng is in grams; specifically, it is carried out according to the orthogonal test oper...

Abstract

The invention relates to a saponin extraction method, especially to a ginsenoside extraction method and an application thereof. The ginsenoside extraction method includes the following steps: (1) a step of early stage treatment, namely a step of placing roots of American ginseng in a baking oven for drying at 70-80 DEG C for 0.3-0.5 h and crushing and sieving the roots; (2) a step of microwave extraction, namely a step of extracting the ginseng for 2-4 times by a microwave extraction method with 40% -50% ethanol and n-butanol having a concentration of 40% -50% as an extraction solvent, whereinthe amount of the ethanol for each time is 3-7 times the weight of the ginseng and the amount of the n-butanol is 1-2 times of the weight of the ginseng, adding glucose having a concentration of 3-6g / 100 ml into the extraction solution for extraction, and obtaining a crude extract of total ginsenosides by microwave extraction, wherein the power of the microwave extraction is 700-800 W and the time of the microwave extraction is 5-10 min; and (3) a step of separation and purification. The ginsenoside extraction method of the invention is high in extraction rate.

Description

technical field [0001] The invention relates to a saponin extraction method, in particular to a ginsenoside extraction method and application thereof. Background technique [0002] Ginseng has the functions of beautifying and hairdressing, and is widely used in cosmetics. The main cause of human skin aging is poor blood circulation, reduced metabolism, and weakened skin elasticity. Because ginseng contains a variety of ginsenosides, amino acids, vitamins and minerals, adding it to skin care products can promote the blood circulation of subcutaneous capillaries, increase the nutrient supply of the skin, prevent arteriosclerosis, and regulate skin moisture balance. Therefore, it can delay skin aging, prevent skin dryness and dehydration, and increase skin elasticity, thereby protecting skin luster and tenderness, preventing and reducing skin wrinkles. Ginseng active substances also have the ability to inhibit the reduction of melanin, making skin white and smooth. [0003] G...
