Embodiment 1

[0018] Get ginseng medical material 100g, pulverize to 16 orders, add 70% ethanol solution to 1000ml soak, add 0.3 gram of sodium lauryl sulfate (K 12 ), heated by microwave for 20 minutes and left to stand for filtration, then add 70% ethanol solution to the residue to soak in 1000ml, leave to filter after microwave for 20 minutes, combine the filtrate to evaporate the solvent on a rotary evaporator, add a small amount of water to disperse, and store in the refrigerator Suction filtration after standing for 24 hours, put the filtrate into the treated macroporous resin column to elute with water and 50% ethanol in turn, and evaporate to dryness to obtain ginsenoside powder with a yield of 6.5%.

Embodiment 2

[0020] Get 100g of ginseng medicinal material, crush it to 16 mesh, add 70% ethanol solution to 1500ml to soak, add 1 gram of sodium dodecylbenzenesulfonate (LAS), heat it with 2450MHz, 240W microwave for 20 minutes, and let it stand and filter. Add 70% ethanol solution to the residue again to soak in 1500ml, heat it in 2450MHz, 240W microwave for 20 minutes, then let it stand and filter, evaporate the combined filtrate to remove the solvent on a rotary evaporator, add a small amount of water to disperse, put it in the refrigerator for 24 hours, and then suction filter. The filtrate was put into the treated macroporous resin column, eluted with water and 50% ethanol in sequence, evaporated to dryness, and the yield of ginsenoside powder was 6.9%.

Embodiment 3

[0022] Take 100g of ginseng medicinal material, crush it to 16 mesh, add 70% ethanol solution to 2000ml for soaking, add 3 grams of cetyltrimethylammonium chloride (1631), heat with 2450MHz, 240W microwave for 20 minutes and then let it stand Filtrate, add 70% ethanol solution to the residue again to soak in 2000ml, heat in 2450MHz, 240W microwave for 20 minutes, then stand and filter, combine the filtrate to evaporate the solvent on a rotary evaporator, add a small amount of water to disperse, and put it in the refrigerator for 24 hours before pumping Filtrate, put the filtrate into the treated macroporous resin column to elute with water and 50% ethanol successively, and evaporate to dryness to obtain ginsenoside powder with a yield of 7.6%.

Abstract

The invention discloses a novel method for extracting ginsenoside from ginseng and application and relates to a novel method for extracting ginsenoside by microwave heating after soaking through an ethanol solution and adding a surface active agent. The traditional product generally has the defects of low yield, high production cost, and the like. The method for extracting ginsenoside from ginseng comprises the following steps of: firstly, pulverizing ginseng into 16 meshes; adding a solution for soaking; adding a surface active agent which is 0.03-0.3 percent of mixture weight; after microwave heating, standing and filtering; adding residues into the solution for soaking, wherein the sum of two solutions for soaking the ginseng is 2 to 20 times of the weight of the ginseng; after microwave heating, standing and filtering; combining filter liquor for evaporating a solvent on a rotating evaporimeter; adding water for dispersing; after placing for 24 hours in a refrigerator, filtering; and placing the filter liquor into a processed macroporous resin column for eluting sequentially by using water and 50 percent ethanol, and evaporating to obtain ginsenoside powder. The invention ensures that microwaves are utilized for the extraction of the ginsenoside as an effective component of the traditional Chinese medicine ginseng.

Description

Technical field: [0001] The invention belongs to the technical field of traditional Chinese medicine preparations, and in particular relates to a new process for extracting ginsenosides. Background technique: [0002] Traditional ginsenoside extraction methods mainly contain the following: 1. Extract with methanol, dissolve in water after removing methanol, degrease with ether, extract with n-butanol and evaporate the solvent to obtain total saponins. 2. Reflux extraction with 95% ether, recover ethanol, add water to dissolve, degrease with petroleum ether, etc., extract with n-butanol and evaporate the solvent to obtain total saponins. 3. Extract with 80% methanol at room temperature, recover methanol, degrease with ether, extract with n-butanol and evaporate the solvent to obtain total saponins. Compared with the traditional reflux extraction process, the process takes a long time, consumes a lot of energy, has disadvantages such as low yield and high production cost. I...
