Embodiment 1

[0054] Embodiment 1: the method for extracting and separating total triterpene acid enrichment liquid from loquat leaf

[0055] The first step of water extraction: take 2kg of dry loquat leaf coarse powder, add 20L of water, mix well, heat to 100 degrees, boil for 60 minutes, cool to below 60 degrees, discard the water extract, and keep the medicinal residue for later use;

[0056] The second step of ethanol extraction: add the dregs and 95% ethanol into the reflux device, heat the extraction for 1 hour, take out the extract, leave the dregs in the reflux device for the next extraction, and repeat the operation 3 times, adding 95% each time Ethanol 20L, the 3 times of ethanol extracts were combined for later use, and the dregs were discarded;

[0057] The third step of coarse filtration: use industrial filter cloth as the medium to filter the ethanol extract, discard the filter residue, and reserve the filtrate;

[0058] The fourth step is a fine filtration: the filtrate is f...

[0060] Embodiment 2: The method for extracting and separating total triterpene acid enrichment liquid from Hedyotis diffusa

[0061] The first step of water extraction: take 2kg of dried Hedyotis diffusa powder, add 20L of water, mix well, heat to 100 degrees, boil for 60 minutes, cool to below 60 degrees, discard the water extract, and keep the drug residue for later use;

[0062] The second step of ethanol extraction: add the dregs and 95% ethanol into the reflux device, heat the extraction for 1 hour, take out the extract, leave the dregs in the reflux device for the next extraction, and repeat the operation 3 times, adding 95% each time Ethanol 20L, the 3 times of ethanol extracts were combined for later use, and the dregs were discarded;

[0063] The third step of coarse filtration: use industrial filter cloth as the medium to filter the ethanol extract, discard the filter residue, and reserve the filtrate;

[0064] The fourth step is a fine filtration: the filtrate is f...

Embodiment 3

[0066] Embodiment 3: the method for extracting capsanthin and capsaicin from red pepper

[0067] The first step of water extraction: Add 2kg of dry red pepper coarse powder and 20L of water into the extraction tank, heat to 100 degrees, keep boiling for 1 hour, cool to 60 degrees Celsius, release the extraction liquid, and keep the residue in the tank for subsequent extraction Extract once, repeat heating and extracting in this way 3 times, combine the 3 times of water extracts for later use, and discard the slag;

[0068] The second step of coarse filtration: use industrial filter cloth as the medium to filter the water extract, discard the filter residue, and reserve the filtrate;

[0069] The third step of fine filtration: the filtrate is filtered with a ceramic membrane with a pore size of 0.003 μm by tangential flow filtration, capsanthin greater than 3kD (kilodaltons) is retained in the mother liquor for other uses, and the filtrate is 1.3mg / ml concentration of capsaici...

Abstract

The invention relates to a method for separating enriched effective components from plant extract, which is characterized in that a multi-stage tangential flow membrane filtration system consists of a first-stage tangential flow membrane ultrafiltration unit, a second-stage tangential flow membrane ultrafiltration unit and until an n-stage tangential flow membrane ultrafiltration unit which are sequentially connected in series. The method disclosed by the invention has the advantages of wide impurity removing range, high separation efficiency, less loss of effective components and small organic solvent and acid-base usage amount, and is easy and convenient to operate.

Description

field of invention [0001] The invention relates to a method for separating and enriching active ingredients from plant extracts. Background of the invention [0002] Plant extracts use plants as raw materials. According to the needs of the extracted final product, through the process of physical and chemical extraction and separation, one or more active ingredients in plants are directional obtained and concentrated (such as flavonoids, alkaloids, Glycosides, acids, polyphenols, polysaccharides, terpenes, etc.), without changing the structure of its active ingredients. Plant extracts are intermediate products, which can be used in pharmaceuticals, health food, tobacco, cosmetic raw materials or auxiliary materials, etc., and have broad market prospects. At present, plant extraction has developed into a new industry with annual sales exceeding 10 billion US dollars. The quality control of plant extracts is often determined by measuring the percentage content of one or sever...
