Embodiment 1

[0037] Weigh 1.1kg of sun-dried ginger and crushed ginger, put them into an enzymatic hydrolysis container, add 3 times the amount of drinking water, stir, heat, control the temperature at 60°C, adjust the pH to 6.0 with dilute hydrochloric acid, add 60g of fiber Vegetable complex enzyme, enzymatic hydrolysis for 6 hours, filtered, distilled in a reduced-pressure evaporator until the relative density of the solution was 1.19, added an appropriate amount of absolute ethanol to make the ethanol concentration of the solution reach 80%, stirred, left standing for 24 hours, filtered, and the filtrate Concentrate to 206.2g.

Embodiment 2

[0039] Weigh 1.1kg of sun-dried ginger, chop it, put it into an enzymatic hydrolysis container, add 1 times the amount of drinking water, stir, heat, control the temperature at 40°C, adjust the pH to 4.0 with dilute hydrochloric acid, add 5g of fiber Vegetable compound enzyme, enzymatic hydrolysis for 2 hours, filtered, distilled in a vacuum evaporator until the relative density of the solution was 1.11, added an appropriate amount of 95% ethanol to make the ethanol concentration of the solution reach 60%, stirred, left standing for 6 hours, filtered, and the filtrate Concentrate to 202.5g.

Embodiment 3

[0041] Weigh 1.1kg of sun-dried ginger, chop it, put it into an enzymatic hydrolysis container, add 2 times the amount of drinking water, stir, heat, control the temperature at 50°C, adjust the pH to 4.5 with dilute hydrochloric acid, add 30g of fiber Vegetable complex enzyme, enzymatic hydrolysis for 4 hours, filtered, distilled in a reduced-pressure evaporator until the relative density of the solution was 1.15, added an appropriate amount of 95% ethanol to make the ethanol concentration of the solution reach 70%, stirred, let stand for 12 hours, filtered, and the filtrate Concentrate to 200.8g.

Abstract

The invention discloses a preparation method of ginger extract. The preparation method mainly comprises the following steps: (1) cleaning ginger, cutting into grains, adding water 1-3 times the grains in mass, stirring, heating while controlling the temperature to 40-60 DEG C, and adding appropriate acid liquid to adjust the pH value of the whole system to 3-6; and adding cellulase for 2-6 hours of enzymolysis, wherein the ratio of the cellulase to the ginger is (50-600mu):1g; filtering; (2) concentrating the filtrate until the relative density is 1.10-1.20; adding an ethanol solution into the filtrate so that the ethanol concentration of the whole solution reaches 60-80%; stirring and standing for 6-24 hours; and filtering and concentrating. The preparation method is simple and easy to operate and has high amplification feasibility.

Description

technical field [0001] The invention relates to a preparation method of a plant extract, in particular to a preparation method of a ginger extract. Background technique [0002] Ginger is a rhizome derived from Zingiberaceae, which is widely used in biomedicine. Ginger extract can be used not only for oral treatment of related diseases, but also for external preparations, mainly for anti-inflammatory and antibacterial effects. The main active components of ginger include volatile oil and gingerol, and the main component of gingerol is 6-gingerol. "Chinese Pharmacopoeia" has also formulated corresponding standards for ginger extract. [0003] Ginger can be planted in a large area in most parts of the country, with a wide range of sources and high medical value. Its extract is widely used as medicine in China, and the components of ginger extract are very complex. The curative effect of the extract obtained by different extraction methods is quite different. Moreover, the e...
