Embodiment 1

[0016] The invention provides a processing method of Polygonum cuspidatum, the steps are: soak 15g of Polygonum cuspidatum medicinal material in 20ml of a pretreatment mixed solution of cellulase and β-glucosidase, after soaking for 10 hours, put it in a microwave oven and process it at 40% power for 25 minutes, That is the microwave processed product of knotweed.

[0017] The weight ratio of the cellulase and β-glucosidase is 1:2.

[0018] The preparation method of the pretreatment mixed solution is as follows: respectively weigh 5 mg of cellulase and 10 mg of β-glucosidase and dissolve them in 30 ml of distilled water, and then take 20 ml of the prepared pretreated mixed solution for processing the above-mentioned Polygonum cuspidatum.

[0019] In order to further verify the beneficial effect of the processing method of Polygonum cuspidatum of the present invention, the following experiments were carried out.

[0020] 1. Investigation of different processing factors.

Embodiment 2

[0031] The invention provides a processing method of Polygonum cuspidatum, the steps are: soak 6g of Polygonum cuspidatum in 10ml of a pretreatment mixed solution of cellulase and β-glucosidase, after soaking for 2 hours, put it in a microwave oven and process it at 80% power for 10 minutes, That is the microwave processed product of knotweed.

[0032] The weight ratio of the cellulase and β-glucosidase is 3:1.

[0033] The preparation method of the pretreatment mixed solution is as follows: respectively weigh 3 mg of cellulase and 1 mg of β-glucosidase and add 10 ml of distilled water to dissolve it, and take 10 ml of the prepared pretreatment mixed solution for the processing of the aforementioned Polygonum cuspidatum.

Embodiment 3

[0035] The invention provides a processing method of Polygonum cuspidatum, the steps are: soak 3.5g of Polygonum cuspidatum in 10ml of pretreatment mixed solution of cellulase and β-glucosidase, after soaking for 10 hours, put it in a microwave oven and process it at 60% power for 20 minutes , that is, the microwave processed product of Polygonum cuspidatum.

[0036] The weight ratio of the cellulase and β-glucosidase is 5:2.

[0037] The preparation method of the pretreatment mixed solution is as follows: respectively weigh 0.5 mg of cellulase and 0.2 mg of β-glucosidase and add 10 ml of distilled water to dissolve it, and take 10 ml of the prepared pretreatment mixed solution for processing the above-mentioned Polygonum cuspidatum.

Abstract

A processing method of giant knotweed rhizome comprises steps as follows: a medicinal material giant knotweed rhizome is immersed in a pretreatment mixed solution of cellulose and beta-glucosidase and processed under different power in a microwave oven, and a microwave processed product of giant knotweed rhizome is obtained; a preparation method of the pretreatment mixed solution is as follows: cellulose and beta-glucosidase are weighed respectively and dissolved with distilled water, and the pretreatment mixed solution is obtained; the weight ratio of cellulose to beta-glucosidase is (1:5)-(5:1). According to the provided processing method of giant knotweed rhizome, content of two effective ingredients of resveratrol and rheum emodin can be remarkably increased simultaneously, the content of polydatin is reduced, and conversion between polydatin and resveratrol in giant knotweed rhizome is accelerated effectively; compared with a conventional processing technology of giant knotweed rhizome, the processing method has no special requirements for temperature, environment and the like, the production conditions are easy to control, the product quality controllability is good, and an effective way applicable to industrial production is provided for application of giant knotweed rhizome, and the processing method has important practical value.

Description

technical field [0001] The invention relates to the field of traditional Chinese medicine processing, in particular to a processing method of Polygonum cuspidatum. Background technique [0002] The traditional Chinese medicine Polygonum cuspidatum is the dried root and rhizome of Polygonum cuspidatum Sieb. et Zucc. It is mainly produced in Jiangxi, Sichuan, Jiangsu, Shandong and other places. It is slightly cold in nature and slightly bitter in taste. Meridian, has the effects of clearing heat and detoxifying, reducing phlegm and relieving cough, promoting dampness and reducing jaundice, dissipating blood stasis and relieving pain. Polygonum cuspidatum mainly contains anthraquinone, stilbene compounds and other components, among which anthraquinone derivatives are mainly in free form, including emodin, emodin methyl ether, chrysophanol and other components, which have antibacterial, liver protection, Laxative, anti-cancer and other functions; and stilbene compounds mainly i...
