Blueberry raw anthocyanidin biological extraction process
Technical field
The present invention relates to technical field of biological extraction, be specifically related to a kind of blueberry raw anthocyanidin biological extraction process.
Background technology
Containing abundant procyanidin nutritional labeling in Blueberry, procyanidin not only has good nourishing healthy and makees
With, also have and prevent that cranial nerve is aging, heart tonifying, anticancer vessel softening, strengthen the functions such as human organism's immunity.Effect of procyanidin
Value expression exists:
(1) antioxidation and removing free radical: OPC are owing to there being the hydroxylic moiety of electron rich in its molecular structure, are excellent
Hydrogen or the donor of neutron, therefore have superpower oxidation resistance, can effectively remove the free radical in human body.Procyanidin exists
Vivo and vitro has antioxidant activity.
(2) protection cardio-cerebrovascular: procyanidin is obvious to the protective effect of cerebral ischemia reperfusion injury;People can be suppressed
The propagation of class skin capillary endothelial cell, affects angiogenesis;Having clear and definite antiplatelet aggregative activity, antithrombotic is made
With substantially;Reduce plasma triglyceride free fatty apolipoprotein B, improve Atherosclerosis Risk index after the meal;Have
Stronger adjustment blood fat, promotes reverse cholesterol transport and accelerates lipid and Cholesterol Excretion, improving the effect of lipid metabolic disorder.
(3) anti-curing cancers: procyanidin has antitumor action, to cervical cancer, many cancers such as carcinoma of prostate, colon cancer
There are prevention and the effect for the treatment of.Additionally, the cancers such as skin carcinoma, oral cancer, hepatocarcinoma are still had certain effect by procyanidin.
(4) prevent with treatment diabetes: procyanidin can improve the oxidised form of diabetic disease states, to insulin sensitivity
The ILA of cell line and antioxidant activity.
(5) antiinflammatory action: procyanidin as antiinflammatory, thus plays antiinflammatory in the macrophage that endotoxin stimulates
Effect.
(6) gastric ulcer injury protection effect: procyanidin can suppress the generation of stress gastric ulcer, suppression gastric mucosa
Secretion acid function, reduces pepsic activity simultaneously.
(7) the liver protecting effect: low dose of (50,100mg L-1) procyanidin can suppress ethanol and tetrachloro-methane induction
Hepatocyte injury and stimulate normal liver cell propagation.
(8) radiation resistance: procyanidin can reduce the Fas protein expression integration of roentgenization skin, increases Bc1-2
Protein expression integration, is allowed to close to normal skin.
(9) enzyme inhibition: procyanidin has inhibitory action to multiple enzyme, it can effectively suppress external pancreatic lipase
Activity, its effect with the degree of polymerization increase and strengthen.
(10) other effects: procyanidin also has mutation, antiallergic, anti HIV-1 virus, antidepressant, antifatigue effect,
Treatment acute respiratory distress syndrome, delays the decline of audition, promotes hair growth and analgesic activity.
At present, blueberry raw anthocyanidin carrying out separation and Extraction and deep processing is always industrial hot spot, external Producer is existing
Utilizing the research that blueberry raw anthocyanidin pharmacy, fine chemical product research and development etc. are relevant, this measure can be substantially improved value of the product and profit
Profit return rate, widens the development space of blueberry industry simultaneously.
