Description
Technical field
The invention belongs to field of natural product extraction, particularly a kind of method extracting anti-oxidation active substance from golden flower Lao Bai tea.
Background technology
Golden flower Lao Bai tea profile mostly is circular pie, its with Lao Bai tea for raw material is refining through material screening, decatize macerates heap, pressed sizing, the operation such as drying, finished product packing of growing dim processes.The good golden flower of quality old white tea cake complexion pool is dark brown, and fragrance is pure, and arohid flavour is strong, flavour alcohol and, soup look orange is bright." golden flower ", formal name used at school coronoid process falls apart capsule bacterium (Eurotium cristatum), be the key factor of achievement golden flower Lao Bai tea distinguishing character, the dense degree of " golden flower " is considered as the core index differentiating the old quality of white tea quality of golden flower, especially the important substance basis of Lao Bai tea health care effect.Lao Bai tea can Effective Regulation human body glycolipid metabolism, has the effect reducing cholesterol, triglyceride and blood sugar in blood of human body.In golden flower Lao Bai tea, the content of Tea Polyphenols is higher, and it is natural antioxidant, can play raising immunity and wait effect with protection is cardiovascular.Also containing the necessary organized enzyme of human body in white tea, can catabolism of fat be promoted, effectively control amount of insulin secretion, sugar unnecessary in decomposer inner blood, promote blood glucose balance.Existing scholar's research finds, the flavanols derivative, Flavonoids etc. of rich content is had mainly to there is flavone compound with the form of glucoside in golden flower Lao Bai tealeaves, its sugar combined is mainly glucose, multiple phenolic hydroxyl group is had in the molecular structure of these compounds, be natural antioxidant, there is important using value.There are some researches show in addition, golden flower Lao Bai tea to staphylococcus aureus, shigella dysenteriae, pneumococcus, typhoid bacillus, A type pays typhoid bacillus, Pseudomonas aeruginosa, expense Shigella flexneri etc. comparatively high inhibition effect and killing action.Golden flower Lao Bai tea decoction has inhibitory action to Fu Shi, sonne bacillus and Escherichia coli.Golden flower Lao Bai tealeaves has clearing heat and detoxicating, astringing to arrest bleeding, pain relieving of drying, stomach invigorating are regulated the flow of vital energy, hypoglycemic, desinsection, enhancing sperm motility, the effect such as antitumor.Found by large quantifier elimination, golden flower Lao Bai tea has very strong antioxidation activity, fully researchs and develops and utilize the oxidation-resistant active ingredient in golden flower Lao Bai tea, develops serial golden flower Lao Bai tea functional food lay the first stone and be significant next step.At present, there are no patent document report in this respect.
Summary of the invention
The invention discloses a kind of method extracting anti-oxidation active substance from golden flower Lao Bai tea, fill up at present there are no the blank of the oxidation-resistant active ingredient specialized in development and utilization golden flower Lao Bai tea, a kind of low cost is provided, is suitable for the method extracting anti-oxidation active substance from golden flower Lao Bai tea of industrialization development.
In order to reach above-mentioned object, the present invention adopts following concrete technical scheme: a kind of method extracting anti-oxidation active substance from golden flower Lao Bai tea, and the step of its extracting method is as follows:
(1) dried in shady and cool place by golden flower Lao Bai tea, micronizer pulverizes, crossing aperture is the sieve of 400 ~ 600 μm, forms golden flower Lao Bai tea leaf powder;
(2) take 6 ~ 10g golden flower Lao Bai tea leaf powder and be placed in 500 ml conical flasks, add the lixiviate in 75 ~ 95 DEG C of hot baths of 250 ~ 400mL distilled water, isothermal vibration lixiviate 15 ~ 30min, repeat lixiviate 2 ~ 3 times, filtration under diminished pressure while hot after lixiviate, filtrate to load in clean container to obtain golden flower Lao Bai tea leaf powder Aqueous extracts, and residue hot distilled water washs;
(3) take the golden flower Lao Bai tea leaf powder water extraction residue that 6 ~ 10g step (2) obtains and be placed in 500 ml conical flasks, adding 250 ~ 400mL concentration is that the ethanolic solution of 20 ~ 40% is at 45 ~ 65 DEG C, isothermal vibration lixiviate 30 ~ 40min, filtration under diminished pressure immediately after lixiviate, filtrate to load in clean container to obtain golden flower Lao Bai tea leaf powder alcohol extract;
(4) utilize the effective polyphenoils in macroporous absorbent resin separation golden flower Lao Bai tea leaf powder Aqueous extracts and alcohol extract, adopt the distilled water wash-out of 6 ~ 8 times of bed volumes, the high-efficiency antioxidant material in stepwise elution purification liquid;
(5) collected by stepwise elution liquid, detect anti-oxidant vigor, select the part reduced pressure distillation and concentration of high-efficiency antioxidant vigor, freeze drying, obtains oxidation resistant product.
As preferably, the model of step (4) described macroporous absorbent resin adopts AB-8, and sample loading mode adopts dynamic loading.
Compared with prior art, the present invention has following outstanding advantages and effect: (1) the present invention adopts the byproduct of golden flower Lao Bai tea industry---and golden flower Lao Bai tea is the active material that strong anti-oxidation prepared by raw material, turns waste into wealth, and is a kind of pollution-free industry; And technique is comparatively simple, comparatively need not invests by large equipment, be very suitable for large-scale industrialized production, develop serial golden flower Lao Bai tea functional food for next step and lay the first stone; (2) the anti-oxidation active substance product prepared by the present invention is applicable to food antioxidant, functional food and pharmaceuticals industry.
Detailed description of the invention
The present invention is described in further detail by following examples, but the present embodiment the technology contents that describes be illustrative, instead of determinate, protection scope of the present invention should do not limited to according to this.
The involved in the present invention method step extracting anti-oxidation active substance from golden flower Lao Bai tea is as follows:
