Problems solved by technology

At present, most of the methods used are to prepare ginsenosides by enzymatic hydrolysis or acid hydrolysis of ginsenosides, and there is no method to directly promote the generation of rare ginsenosides by optimizing the extraction conditions in the extraction process of ginsenosides. There is no use of vitamin C as a catalyst to hydrolyze to obtain rich and rare ginsenoside Rg 3 Extraction method of ginsenosides

Embodiment 1

[0028] single factor test

[0029] Taking the extraction rate of total ginsenosides (that is, the mass of total ginsenosides in the extract as a percentage of the total mass of the sample) as an index, a single factor investigation was carried out on the ethanol concentration, dosage, and microwave extraction times. The optimal levels of each single factor obtained are ethanol concentration 70% (V / V), dosage 15 times the weight of ginseng (ml / g), and extraction times 2 times.

[0030] Orthogonal experiment

[0031]In order to optimize the experimental conditions of microwave heating and extraction, under the condition that the above-mentioned ethanol concentration, dosage, and extraction times were constant, microwave power (A), vitamin C concentration (B), and extraction time (C) were selected as investigation factors (as shown in the table 1), take three levels for each factor, and conduct an orthogonal experiment according to Table 2. The obtained extract was enriched wit...

Embodiment 2

[0037] The content analysis of ginsenoside composition in the extract of embodiment 2

[0038] The preparation of ginsenoside extract A: take 2.5 grams of ginseng samples, use 50ml70% (V / V) ethanol to ultrasonically extract 2 times at room temperature, each time for 60 minutes, extract the solvent under reduced pressure at 40 ° C, Concentrate into an aqueous solution, use macroporous adsorption resin to enrich and purify total ginseng saponins, first elute with 5BV deionized water to remove impurities, then enrich total ginsenosides with 7BV60% ethanol, and purify saponins, the elution rate is 1.5ml / min. Collect the ethanol eluate, remove the appropriate amount of ethanol by rotary evaporation, put the concentrated solution in a stainless steel plate, evaporate to dryness on a water bath, and dry under reduced pressure at 60°C to obtain ginsenoside extract A.

[0039] Preparation of ginsenoside extract B: Weigh 2.5 grams of ginseng sample, place it in the extraction tank of ...

Embodiment 3

[0050] Weigh 3 grams of ginseng sample, place it in the extraction tank of the microwave extractor, add 45ml of 70% (V / V) ethanol solution and 0.9 gram of vitamin C, set the extraction power to 350W, and the extraction time is 30 minutes. After the extraction is completed, The filtrate was collected, and 45ml of 70% (V / V) ethanol solution and 0.6 g of vitamin C were added to the filter residue again, and the filtrate was collected after extraction under the same extraction conditions. The two filtrates were combined, rotary evaporated to a volume of about 20ml, and the pH value was adjusted to 7.0 with concentrated ammonia water, and the macroporous adsorption resin was used to enrich and purify the total ginseng saponins. The total ginsenosides were enriched with ethanol, and the saponins were purified with an elution rate of 1.5ml / min. Collect the ethanol eluent, remove the appropriate amount of ethanol by rotary evaporation, put the concentrated solution in a stainless stee...

Abstract

The invention relates to total ginsenoside rich in ginsenoside Rg3 and an extracting method thereof. The extract comprises, by mass, 1.0-3.0% of ginsenoside Rb1, 0.2-1.0% of ginsenoside Rb2, 0.5-2.5% of ginsenoside Rb3, 0.5-2.5% of ginsenoside RC and 28-40% of ginsenoside Rg3. The extracting method comprises the following steps that ethyl alcohol is used as an extracting solvent for extracting ginseng through a microwave extracting method, a certain amount of vitamin C is added into the extracting solution, a crude extracting solution of the total ginsenoside is extracted through microwave heating within a certain period of time, and the crude extracting solution of the total ginsenoside is further enriched and purified through a macroporous resin adsorption process to obtain the extract of total ginsenoside.

Description

technical field [0001] The present invention relates to a kind of ginsenoside and its extraction method, more specifically, to a kind of ginsenoside rich in ginseng rare saponin and its extraction method, especially a kind of ginsenoside rich in ginsenoside which utilizes vitamin C catalytic technology and microwave heating method.
