Problems solved by technology

The method provides a better method for preparing 6-gingerol and 8-gingerol from ginger, but there are still following deficiencies: one is: the method takes the chemical extraction method of ginger powder as the core, extracts The process is long, time-consuming and labor-intensive; the second is that the extraction process uses a large amount of organic solvents, which is unfavorable for maintaining the biological activity of ginger and improving its medical efficacy; therefore how to seek a biological method that is simple, time-saving and labor-saving, and can maintain ginger. The method of preparing 6-gingerol and 8-gingerol from ginger based on activity and mechanical physical extraction and the special ultrafiltration device are still a problem to be solved urgently for those skilled in the art

Embodiment 1

[0024] A method for preparing 6-gingerol and 8-gingerol from ginger according to Example 1 of the present invention includes the following items in turn: raw material treatment, mixing and homogenization of ginger, removal of impurities to obtain the initial extract, and ultrafiltration to obtain the initial extract. It is prepared by the process steps of pure product and nanofiltration, as follows:

[0025] 1. Raw material processing: raw material processing is to take fresh ginger to remove the roots and petioles, wash it with water, and then pulverize it in a blender;

[0026] 2. Mixing and homogenizing: After the above-mentioned ginger powder is mixed with a mixed solvent of 3 times the volume of ethanol and water, homogenize in a high-speed homogenizer for 0.5 hours;

[0027] 3. Removing impurities: press-filter the mixed homogenate in an air pressure filter tank with an air pressure of 0.5MPA, and pass through a 300-mesh sieve.

[0028] 4. Ultrafiltration: It is the fil...

Abstract

The invention discloses a method for preparing 6-gingerol and 8-gingerol from ginger and an ultrafiltration device thereof and belongs to the technical field of the preparation method of natural active products. The method disclosed by the invention sequentially comprises the steps of treating the raw material of the ginger, mixing the homogenate, removing the impurities to obtain a primary extractive, ultra-filtrating to obtain a primary product, and nano-filtrating to obtain a pure product. The ultrafiltration device comprises at least one shell and a pipe unit communicated with the inner cavity of the shell; a closed tubular ultra-filtration is arranged in the inner cavity of the shell; two pipes communicated with the inner cavity of the ultra-filtration are arranged on the upper end part of the ultra-filtration; and an ultrafiltration membrane capable of allowing materials to be filtered to enter a hollow cavity between the ultra-filtration and the shell from the inner cavity of the ultra-filtration is arranged on the tubular wall of the ultra-filtration. Compared with the prior art, the invention has the substantive characteristics and the remarkable progresses of easily-controlled preparation process, convenient and simple operational process, high production efficiency, suitability for large-scale of factory production and capability of improving the level of the health of people.

Description

technical field [0001] The invention relates to the technical field of preparation methods of natural active products, in particular to a method for preparing 6-gingerol and 8-gingerol from ginger and the technical field of an ultrafiltration device. Background technique [0002] Ginger is the fresh rhizome of Zingiber officinalis Zingiber officinalis, which is an indispensable food commonly used in daily life, and is also an important traditional Chinese medicine in traditional Chinese medicine. Ginger, also known as fresh ginger, has a pungent taste and slightly warm nature, and returns to the lung, spleen, and stomach meridians. It has the effects of relieving the exterior and dispelling cold, warming the middle and relieving vomiting, resolving phlegm and relieving cough. Indications for wind-cold cold, stomach-cold vomiting, cold phlegm and cough embolism. Modern studies have found that ginger has many biological activities such as improving the activity of digestive ...
