Problems solved by technology

When extracting by solvent method, in order to obtain all the water-soluble and fat-soluble components and components, it is generally necessary to use some flammable, explosive and toxic lipophilic organic solvents; and the active substances extracted by using these organic solvents, in It is usually impossible to solve the residue problem in medicine, veterinary medicine, food and feed products; in addition, the use of the above-mentioned organic solvents is also a safety problem that is difficult to solve in the field of industrial production

Embodiment Construction

[0022] Now in conjunction with accompanying drawing, the present invention will be further described:

[0023] A two-step enzyme method is used to prepare the standard extract of moso bamboo leaves. The preparation method is: the moso bamboo leaves of the bamboo subfamily Bamboo genus are used as raw materials, and the enzyme reaction is carried out in a non-aqueous medium in an enzyme reactor. The non-aqueous medium Composed of deionized water, food grade ethanol;

[0024] and get the extract as follows:

[0025] 1), the collection of bamboo leaf raw materials,

[0026] The bamboo leaves are taken from the place of origin with no pollution around, no pesticide and heavy metal residues, and the content of arsenic and heavy metals in pesticides should meet the GB-9986 standard. %, save for later use;

[0027] 2), cleaning, drying and pulverizing of bamboo leaf raw material,

[0028] With drinking water for urban residents meeting GB 5749-2006, wash the bamboo leaves, dehydr...

Abstract

A two-step enzyme method used for preparing the standard extractive of a moso bamboo belongs to the extracting technical field of the natural active substance components. The invention is characterized in that bamboo leaves of moso bamboo are taken as raw materials; the standard extractive is obtained by the following steps: before reaction, the bamboo leaves are collected, washed, dried and crashed; one-step enzyme reaction and two-step enzyme reaction are treated later; a first liquor drainage and a second liquor drainage are blended; deslagging, centrifuging and the separation of dreg and liquid are carried out; in a third liquor drainage and a fourth liquor drainage, the pH value is equal to the pH value of the first liquor drainage and the second liquor drainage; the standard extractive is obtained by blending the first, the second miscible liquids and third, the fourth miscible liquids. After the invention is implemented, the positive effect is that: the bamboo leaves chosen by the invention has low cost, rich resources; the whole course of cultivating, collecting and processing does not have pollution, toxic hazard so that the final extractive does not have pollution, toxic hazard; the characteristics provide wide prospect for the popularization of the extractive.

Description

technical field [0001] The invention belongs to the technical field of extraction of natural active material components, and in particular relates to the extraction technology of natural active material components of moso bamboo leaves. Background technique [0002] Conventional extraction methods of plant natural active substances mostly adopt solvent method. When extracting by solvent method, in order to obtain all the water-soluble and fat-soluble components and components, it is generally necessary to use some flammable, explosive and toxic lipophilic organic solvents; and the active substances extracted by using these organic solvents, in It is usually impossible to solve the residue problem in medicine, veterinary medicine, food and feed products; in addition, the use of the above-mentioned organic solvents is also a safety problem that is difficult to solve in the field of industrial production. Contents of the invention [0003] The present invention provides no s...
