Embodiment 1

[0041] Embodiment 1: Prepare galactitol extract or galactitol with meat from Rong Rong as raw material

[0042] 1. Take 200g of dried meat with scale leaves removed from impurities, cut into small pieces, and crush them into 20-mesh granules;

[0043] 2. First heat and reflux extraction with 10 times the amount of 70% ethanol for 2 hours, and then use 8 times the amount of 70% ethanol for reflux extraction twice, each time for 1 hour;

[0044] 3. Combine the extracts, concentrate under reduced pressure to extract, add ethanol to 50% alcohol content, let stand overnight, and filter;

[0045] 4. Concentrate the filtrate under reduced pressure, add water to dissolve, and put the water on the SP825 macroporous adsorption resin column. Eluted with water, collected fractions containing galactitol (positive for o-dihydroxyl reaction), concentrated under reduced pressure to a thick paste, then freeze-dried to obtain galactitol extract, recrystallized with ethanol to obtain colorless cr...

Embodiment 2

[0046] Embodiment 2: Extracting and preparing galactitol or its extract from the meat from the waste residue liquid of the glucoside

[0047] 1. Take the waste residue (500g) of the water eluent (500g) that extracts the phenylethanol glycoside component from the minced meat, add 10 times the amount of 70% ethanol to soak and percolate for 72 hours, and then soak it with 8 times the amount of 70% ethanol Percolation extraction twice, 48 hours each time;

[0048] 2. Combine the extracts, concentrate under reduced pressure, add water to dissolve, and put granular activated carbon column resin column on the water liquid. Eluted with water, collected fractions containing galactitol (positive for o-dihydroxyl reaction), concentrated under reduced pressure to a thick paste, then spray-dried to obtain galactitol extract, recrystallized with ethanol to obtain colorless crystals Galactitol.

Embodiment 3

[0049] Embodiment 3: Preparation of a kind of natural galactitol laxative health care tea

[0050] Take 1 kg of high-quality black tea and 80 g of cyclodextrin, soak it in 10 kg of double distilled water in an 80°C water bath for 30 minutes, and soak the filter residue in 8 kg of double distilled water in an 80°C water bath for extraction twice, each time for 20 minutes. The filtrates obtained from the three times were combined, concentrated under reduced pressure to form a thick paste, and spray-dried in a tower temperature of 95°C to obtain about 200 g of tea active ingredient extraction dry powder. Combine the spray-dried 100g phenylethanol total glycosides extract of Cistanche cistanche, 100g natural galactitol and the above-mentioned dry tea extract powder, add 50g dextrin and 20g sweetin, sieve through an 80-mesh sieve repeatedly, and spray 75% ethanol Soft materials. The soft material is granulated through a 12-mesh sieve, dried at 60°C, and then granulated through a 1...

Abstract

The invention provides a method for extracting and preparing galactitol and a component containing the galactitol from a cistanche medicinal material or waste residue liquid of cistanche glycoside extraction. The galactitol is an active constituent of the cistanche for taking the effect of loosing the bowel to relieve constipation and can be used as an additive of a functional health-care food preparation. The invention solves the problem of sufficient utilization of cistanche water-soluble residue liquid, improves the utilization value of cistanche plant resources and has good market development prospect.

Description

technical field [0001] The invention relates to a method for extracting and separating galactitol and galactitol extract from Cistanche deserticola and Cistanche deserticola glycosides waste residue liquid, and also relates to their application in functional foods and health care products for relaxing bowel and defecating. Background technique [0002] The traditional Chinese medicine Cistanche Herba Cistanches is the dry fleshy stem with scaly leaves of the plant Cistanche Hoffmg.EtLink of Orobanchaceae Cistanche. Efficacy, is a famous tonic Chinese medicine. It has the highest frequency of occurrence in the prescriptions for nourishing kidney and yang in the past dynasties, and its probability in anti-aging and anti-aging traditional Chinese medicine prescriptions is second only to ginseng, so it is also called "desert ginseng". Because of its definite curative effect, mild medicinal properties, nourishing but not harsh, and nourishing but not dry, Cistanche is widely use...
