Technical background
The medicines and health protection of ginkgo leaf is worth and is disclosed by Chinese scholars, ginkgo leaf contains more than 20 kind of flavone compound, its content greater than 24%, mainly contains ginkgo diketone (Cinkgetin), Isoginkgetin (So ginkgetin), bilobetin (Bilobetin) in total extract.Also contain the terpene lactones compound in the ginkgo leaf, diterpenoid-lactone mainly contains ginkgolides (Ginkgolide) A, B, C, M, J etc., and sesquiterpene lactone is Bilobalide (Bilobalide).In addition, also contain phenols, 25 kinds of beneficial elements, 17 seed amino acids, alkaloid etc.Modern study has the cardio and vascular function of improvement, relievings asthma, coronary artery dilating, resist myocardial ischemia, hemangiectasis, step-down, anti-platelet activating factor, inhibition platelet aggregation, delay senility, strengthen immunologic function, improve learning and memory function, anti-inflammatory, protect the liver, fall blood ester, the effect such as anticancer.Modern Application is used as the therapeutic agent of the diseases such as coronary heart disease, cerebral apoplexy, hyperlipidemia, diabetes, bronchial astehma, chronic bronchitis, and successful (Shen Yingjun waits the pharmacology of Chinese materia medica People's Health Publisher, and 2006,1040-1047).At present both at home and abroad medical science men's clinical trial proves, and ginkgo leaf health care tea is the new type of health tea of the treatment cerebrovascular and cardiovascular artery sclerosis, hypertension, diabetes, senile dementia.
Tealeaves; development along with science and technology; particularly since the seventies in last century; Japan and the United States and China have carried out a large amount of tealeaves to the research of the health care of human body; especially since the later stage eighties; multi-disciplinary intersection and infiltration obtain many breakthrough achievements, and are following the scale pattern of an ex vivo experiment-in vivo experiment-clinical trial-epidemiological study so that the health-care efficacy research of tealeaves has entered a leap.These important achievement have: tealeaves is to the inhibition (1975 of propagation of cancer cells; 1979); preventing decayed tooth (1981); antioxidation (1983); anti-platelet aggregation (1983); active anticancer (1984); hypotensive (1985); reducing blood lipid (1985); antiulcer (1987); suppress AIDS (HIV virus) (1990); antiallergy (1990); resisiting influenza virus (1990); clear and definite tealeaves is without carcinogenesis (1991); liver protecting (1992); improve intestine immunity (1992); anti-asthma (1990).
The chemical composition that exists in the tealeaves, of a great variety, found kind more than 400, just human body is had obvious health-care effect.Can be divided into organic principle, comprise other joint compounds such as Tea Polyphenols, vitamin, amino acid, pigment and lipopolysaccharides, caffeine; Another kind of is the inorganic constituents of tealeaves, i.e. mineral element.Comprise the various trace elements of needed by human, in tealeaves, all exist.Trace Elements in Tea has caused the attention of tea science man and even Medical scientists to the effect that health produces.
Tea Polyphenols is the compound with phenol chemical constitution that is present in tea, found kind more than 30, wherein catechin accounts for about 70% of Tea Polyphenols total amount, is not only one of main body of tealeaves green tea composition, and is the important component why tealeaves has health care.Tealeaves contained vitamin kind is quite a lot of, as human body day the replenishing of requirement, is more satisfactory, and particularly vitamin C and content of vitamin E are quite abundant, all have anti-ageing and oxidation resistant effect.
Yellow tea, the origin of name: people find that from roasted green tea owing to complete, knead rear dry deficiency or untimely, the flavescence of leaf look is so produced new category-yellow tea.Yellow tea is made with green tea similarity, and difference is many together vexed heap operations, and this vexed heap process is the main feature of yellow tea method for making, also be it with the basic distinction of green tea, green tea is without fermentation, and yellow tea is to belong to the fermentation teas.Yellow liquor color is apricot yellow bright and clean, and the flavour glycol is bright refreshing, and fragrant high, dense, the anti-bubble of flavor has delicate fragrance sense profusely after the drink, really be " dislike steathily graceful pretty peach tasteless, the normal pretty young woman's medicine of pounding medicine in a mortar is not fragrant ".(the Tang Dynasty Xue's energy " thank to husband Liu and post Tianzhu tea " verse).Yellow tea is cold in nature, has detoxifcation and brings down a fever and fall effect of fire.The basic manufacturing process of yellow tea is vexed through completing, piling, dry three processes all, and vexed heap process causes the profound change of material in the tealeaves through hyther or microbial action.Contain chlorophyll, carrotene and lutein in the bright leaf of yellow tea, chlorophyll is destroyed after the processing, and lutein and carrotene are occupied an leading position.Lutein and carrotene are referred to as carotenoid, in long-time hot and humid condition carotenoid generation cyclisation, produce the irisone with gillyflower fragrance.Simultaneously, in the vexed heap process of yellow tea, there is microorganism to grow in a large number, these microorganisms can be decomposed into the small-molecule substances such as alcohol, aldehyde, organic acid, carbon dioxide with large molecule glucide and crude fat, also protein is decomposed into amino acid, these processes are that yellow tea forms unique flavour characteristics and lays a good foundation.Yellow tea is fermented tea, in its sweat, can produce a large amount of digestive ferments, the most beneficial to taste, to indigestion, poor appetite, lazy moving fat, all can drink and change it, the active ingredient of yellow tea can make adipocyte recover metabolic function under the effect of digestive ferment, and fat is eliminated.
A kind of trophism health protection tea of ginkgo leaf and the composite composition of yellow tea, can make the elderly in drinking tea, obtain health-care efficacy, the new type of health tea of the control cerebrovascular and cardiovascular artery sclerosis, hypertension, senile dementia, particularly to drinking and to play better health-care effect with indigestion, poor appetite, lazy moving overweight people.
The health protection tea that single ginkgo leave tea of the prior art or ginkgo leaf and tealeaves assembly and ginkgo leaf and other useful raw material assembly things are prepared into, ubiquity has been ignored the effect of utilizing of effective component of ginkgo leaf, the result causes its product weak effect, be difficult to reach the anticipation effect, thereby affected consumer's cognition degree, be difficult to promote.Trace it to its cause, the one, ginkgo leaf since growth period its cell membrane, the continuous lignifying of cell membrane, plucking time is different, its Texture Difference is very large, main component in the ginkgo leaf is the organic principles such as the bilobanone compound that wherein contains, lactone compound, poly-isoamyl alcohol and polysaccharides from ginkgo biloba besides, make tea after, simple boiling water soaks, being difficult to its fat-soluble active ingredient is leached, is to cause drinking the undesirable main cause of rear effect.The 2nd, existing processing technology is unreasonable, only is simple method for preparing tea, is difficult to reach the medical curative effect of ginkgo leaf, can not realize the medical value of existing ginkgo leave tea.
Along with the problem of middle-aged and old cardiovascular and cerebrovascular health more and more receives publicity, the health care that improves ginkgo leaf is worth is combined with the good characteristic that yellow tea has, and should be able to address the above problem better.Bad for digestive functions especially, fat crowd can bring into play special health-care effect, but there is not yet relevant report in the prior art.
