Description
One, technical field
The present invention relates to a kind of Folium Camelliae sinensis preparation, particularly fresh tea juice preparation and preparation method thereof.
Two, background technology
Studies show that people's hypertension, the coronary heart disease prevalence lower (Zhao Guangsheng, Yuan Xiaoyuan, the Gong Bangqiang etc. that often drink tea.China's cardiovascular magazine 1990,18 (1): 35), research has proved that also tea polysaccharide is its main pharmaceutical component, these compositions have hypoglycemic effect, (clear water Cen husband, tea (day) 1987,3:24,), have the effect of blood fat reducing, the effect of raise immunity, (Wang Dongfeng, Xie Xiaofeng, Cai Chengyong etc., Chinese herbal medicine, 1995,26 (5) 225) has blood pressure lowering, decreased heart rate, increase effect (Wang Dinggang, the Wang Shuru of coronary flow, China Medicine University's journal, 1991,22 (4): 225), have the antithrombotic effect (Wang Shuru of anticoagulation, Wang Dinggang, Chinese herbal medicine, 1992,23 (5): 254), tea polysaccharide also has the effect (Wang Dinggang that improves anoxia enduring, Wang Shuru, Folium Camelliae sinensis, 1992,2:4)
Other there are some researches prove the polyphenols in the Folium Camelliae sinensis have antitumor, antimutagenic effect (1994,1427 (1): 217), the polyphenols in the Folium Camelliae sinensis is anticancer, the mechanism of mutation mainly contains the following aspects for Hirose M, et.Cancer Res:
1. to free radical resisting: free radical causes body nucleic acid, protein metabolism is unusual, take place with tumor, develop relevant, (Chung FL, et al.AnnNy AcadSci, 1993,686:186) 2. blocking nitrosamine formation synthesizes (Tanaka K, et al.Mutaat Res, 1998,412 (1): 91) 3. influence multiple metabolism younger sister activity, can suppress the activity that somatomedin and tumor promoter etc. act on tyrosine kinase, thereby make some tyrosine protein can not phosphorylation, suppress growth (KenneedyDO, the et al.ChemBiol Interact of cell, 1998,110:159) 4. raise immunity studies show that in the body that the polyphenols in the Folium Camelliae sinensis can obviously increase the NK cytoactive, and with γ IL-2 co-induction LAK cytoactive, increase IL-2 secretion and IL-2Mr-Na expression (the Raleigh group, etc.The immune magazine of China, 1995,11 (5): 294) 5. regulator gene is expressed and be apoptosis-induced: the tea catechin that extracts from Folium Camelliae sinensis can be induced apoptosis (the Basami H of stomach cancer cell, et al.Oncol Rep, 1998,5 (2): the tea catechin that 527) extracts from Folium Camelliae sinensis in addition also can suppress epidermal carcinoma cell, synthetic (the Liang YC of leukocytic DNA, et al.J Cell Biochem, 1997,67 (1): 55) 6. type ii diabetes is had significant auxiliary treatment effect (Zhang Yuye, Liu Yanping, Xie Liusheng, Wei Chonghuan, Chinese herbal medicine, 2001,32 (7): 632).
Though there is the functional components of many useful human healths in the Folium Camelliae sinensis, imitate the magnitude relation rule according to pharmacy, there is not reasonable dosage to be difficult for reaching pharmacodynamic feature, take in the Folium Camelliae sinensis functional components in the mode of having tea and have the different intake differences of different tea leaf quality content of functional component, the different intake differences of functional components dissolution in the different mode of the making tea Folium Camelliae sinensis, the functional components that non-timed is quantitatively taken in the Folium Camelliae sinensis can not form stabilizing effective blood medicine content in vivo, and existing Folium Camelliae sinensis drinking way reaches the active effect of embodiment Folium Camelliae sinensis functional components and exists dosage groundless, content does not have standard, quantitatively difficult operation, usage is random or the like defective effect the functional components in the Folium Camelliae sinensis play a role.
Drink the instant tea of more convenient existing improvement drinking way in order to make Folium Camelliae sinensis, filling liquid tea, the maximum defective of this invention of patented invention 88103042.2 (technology for processing instant tea) that proposes as university of Zhejiang Agricultural Univ is that Folium Camelliae sinensis is handled without enzyme denaturing, organized enzyme in the Folium Camelliae sinensis is 20 ℃ of increased activity, 45～55 ℃ of activity are the strongest, the activity of enzyme can produce the main function composition polyphenols enzymatic oxidation in the Folium Camelliae sinensis, make polyphenols lose original activity (white Kun unit, Tea Processing, Beijing Chemical Industry Press 2001) this is invented at crushing process, expressing process, 50～70kg/cm
2Pressure ultrafiltration technology process all may be in 20～55 ℃ of the strongest temperature ranges of enzymatic activity, and is uncertain with the instant tea biological activity that this process is produced.
Also there is certain defective in the extraction of another kind of functional materials tea polysaccharide with processing in the existing Folium Camelliae sinensis, apply for as Shanghai Chinese Medicine Creation Research Center, the purification Folium Camelliae sinensis polysaccharide of Hui Yongzheng invention and extracting method application number are 02110999.0 to have adopted the toxic solvent petroleum ether, acetone solvent extracts, also adopted and to have made tea polysaccharide heated denaturalization drying process with atomizing, the existing tea polysaccharide that studies show that is that acidic polysaccharose easily decomposes under alkaline heating state, to poor heat stability, with baking temperature rising color burn, polyphenols contained in the Folium Camelliae sinensis can become o-quinone by autoxidation under heat effect, tea polyphenols major part in the black tea is in course of processing oxidation (white Kun unit, Tea Processing, Beijing, Chemical Industry Press 2001) this has just illustrated that the functional components in the Folium Camelliae sinensis is subjected to thermally labile.
