Problems solved by technology

At present, there are many kinds of jujube processing products in China, including: candied dates, jujube tonic crystals, jujube tea, jujube paste, jujube wine, jujube red pigment, etc., but these products are generally rough processed products, which are made from the whole jujube pulp The implementation generally does not involve the separation and extraction of active ingredients, and does not make the best use of everything, so it is difficult to guarantee the health benefits of the product

Embodiment

[0017] The jujube is pitted (yield is about 85%), dried, cooled to room temperature, crushed, passed through a 40-mesh sieve, mixed with 50 kg of an equivalent amount of 75% ethanol, put into a percolation bucket, and mixed with 75% ethanol at room temperature. Percolation and extraction, collecting 200 kg of the extract, centrifuging the residue to remove the residual solvent, and then drying in a vacuum drying oven to obtain about 10 kg of jujube dietary cellulose, which is crushed and passed through a 60-mesh sieve, and directly compressed into a 1-gram tablet. Jujube dietary cellulose tablets; combine the extracts, filter with diatomaceous earth, concentrate and recover ethanol to a total volume of 60 liters, cool to below 25°C, extract twice with 60 liters of ethyl acetate, combine the extracts, Solvent is evaporated and recovered under Mpa vacuum degree to obtain 0.4kg of paste jujube wax; the raffinate is concentrated to 65-70% (weight), and about 40kg of jujube cyclic n...

Abstract

The pulp of ripe data, after being dried, cooled and crushed, is ethanol extracted; the residual dreg after ethanol extraction is steamed and dried to produce dietary fiber powder; the extracted liquid is concentrated to recover ethanol and extracted with organic solvent to separate data wax; and the raffinate is concentrated to obtain date cyclic nucleotide syrup. The said process can produce several kinds of data products of different active components and different physical and chemical property, and the data products include functional health dietary fiber and date cyclic nucleotide syrup as tonic for people with delicate constitution.

Description

technical field [0001] The present invention relates to the extraction technology of the active ingredient of the plant fruit, more specifically a method for extracting the bioactive ingredient from jujube. Background technique [0002] Jujube is a plant of the genus Jujube in the family Rhamnaceae, and its fruit contains a variety of biologically active components (including: cyclic adenosine monophosphate, cyclic peptide alkaloids, plant polysaccharides, pectin, ascorbic acid, ursolic acid, oleanolic acid, organic acids and Mineral nutrients, etc.), has a variety of pharmacological effects, and is listed as a variety of medicine and food by the Ministry of Health, and is a unique biological resource in my country. At present, there are many kinds of jujube processing products in China, including: candied dates, jujube tonic crystals, jujube tea, jujube paste, jujube wine, jujube red pigment, etc., but these products are generally rough processed products, which are made fro...
