Description
Technical Field
The invention belongs to the field of traditional Chinese medicines, and particularly relates to a method for extracting a polygonatum sibiricum extract by adopting a nine-steaming and nine-sun-drying process.
Background
The sealwort is also named as the gorgon fruit and the tiger ginseng, has the functions of reducing blood pressure, blood fat and blood sugar, preventing atherosclerosis, delaying senility, resisting bacteria and the like, and is a valuable traditional Chinese medicine. The existing method is to soak the polygonatum rhizome in wine and tea and discard the polygonatum rhizome residue, but the solvent in the prior art is single yellow wine or pure water, and the polygonatum rhizome has few nutritional ingredients dissolved in the solvent, so the polygonatum rhizome is not fully utilized.
Disclosure of Invention
In order to solve the problems, the application provides a method for extracting a polygonatum sibiricum extract by adopting a nine-steaming and nine-sun-drying process.
In order to achieve the purpose, the invention adopts the following technical scheme:
a method for extracting rhizoma Polygonati extract by nine times of steaming and sun drying comprises the following steps: (1) drying the fresh rhizoma polygonati washed with soil by cold air until the water content is 30-40%; (2) soaking the air-dried rhizoma polygonati in yellow wine for 2-3h, wherein the proportion of the rhizoma polygonati to the yellow wine is that 300-500 g of yellow wine is added to each kilogram of rhizoma polygonati, and after soaking, draining the redundant yellow wine; (3) steaming rhizoma Polygonati soaked in yellow wine in steam for 30-50min, and sun drying; (4) repeating the step (3) eight times; (5) crushing the polygonatum kingianum which is steamed and dried for nine times, adding an extraction solvent, and performing ultrasonic extraction for 3-3.5 hours, wherein the ratio of the extraction solvent to the polygonatum kingianum is that 10-12 kg of the extraction solvent is added to each kg of the polygonatum kingianum, and the extraction solvent consists of water, ethanol, glycerol and fatty acid sucrose polyester; (6) and after the ultrasonic extraction is finished, filtering, collecting filtrate, and concentrating the filtrate into paste to obtain the sealwort extract.
In the scheme, before extraction, the polygonatum is treated by adopting a nine-steaming and nine-sun-drying process, so that irritant substances in the polygonatum can be degraded, and after the polygonatum is subjected to the nine-steaming and nine-sun-drying process, the content of beneficial ingredients is increased; before the polygonatum sibiricum is steamed and aired for nine times, yellow wine is used for soaking the dry polygonatum sibiricum, alcohol and water in the yellow wine permeate into the polygonatum sibiricum, the steaming time of the polygonatum sibiricum is shortened, and a large number of nutrient substances are also contained in the yellow wine, and the nutrient substances are added into the polygonatum sibiricum, so that the nutrient value of the polygonatum sibiricum is improved.
Further, the preparation method of the extraction solvent comprises the steps of adding 20-30 parts by weight of ethanol, 3-5 parts by weight of glycerol, 1-3 parts by weight of fatty acid sucrose polyester and 0.8-1 part by weight of alkyl glycoside into 100 parts by weight of water, and performing ultrasonic dispersion uniformly.
In the scheme, the extraction solvent consists of water, ethanol, glycerol, fatty acid sucrose polyester and alkyl glycoside, wherein the water and the ethanol are main solvents, the fatty acid sucrose polyester and the alkyl glycoside are used as solubility improving agents to improve the solubility of components which are not easy to dissolve in the solvent in the polygonatum sibiricum, so that more dissolved substances of the polygonatum sibiricum are dissolved in the extraction solvent, particularly the solubility of lignans in the polygonatum sibiricum is difficult to dissolve in water, and the content of the lignans is greatly increased due to the action of the fatty acid sucrose polyester and the alkyl glycoside in the extraction solvent in the invention compared with that of pure water as the extraction solvent, and compared with that of ethanol as the extraction solvent, the content of the lignans is equivalent, but the content of other nutritional components is greatly increased, such as some elements like calcium and magnesium and steroid glycoside compounds; and the glycerol, the fatty acid sucrose polyester and the alkyl sugar in the extraction solvent are used in a matching way, so that the loss of the volatile oil in the rhizoma polygonati can be reduced. And the content of the nutrient components of the obtained polygonatum sibiricum extract is not greatly different within the range of the weight part ratio.
Further, in the step (5), before adding the extraction solvent, adding pure water, keeping the temperature of the system at 40-50 ℃, adding the biological enzyme into the system, reacting for 10-20min, then adding the extraction solvent, and performing ultrasonic extraction for 2-2.5h, wherein the adding amount of the pure water is that 200 grams of pure water is added into each kilogram of rhizoma polygonati. Before extraction, enzymolysis is carried out on the polygonatum sibiricum which is steamed and dried for nine times, so that a target extract in the polygonatum sibiricum is easier to dissolve out, the extraction time is shortened, and the ultrasonic extraction can be carried out for 3-3.5h and can be shortened to 2-2.5 h.
Furthermore, the adding amount of the biological enzyme is that 50-60 g of the biological enzyme is added into every kilogram of rhizoma polygonati.
Further, the biological enzyme is composed of cellulase and pectinase, wherein the cellulase accounts for 70wt%, and the pectinase accounts for 30 wt%.
Compared with the prior art, the invention has the beneficial effects that:
the invention carries out nine-steaming and nine-sunning treatment on the sealwort, and then extracts the sealwort to obtain the sealwort extract with various and high content of nutrient components, thereby improving the utilization rate of the nutrient components in the sealwort.
