                          CATECHINES (TEA POLYPHENOLS)


  Catchiness are the principal constituents of tea polyphones China tea is rich in catechines, the content is leaves is about 15-20% of dry weight.
  Catechins complex is consist of six complex is six compounds which are (—)-Epigallocatechin gallate (EGCG), (—)-Epicatechin gallate (EGC), -Epicatechin, (±)-gallocatechine (±GC), (±)-Catechine (±C).
  we Produces the milk-white or light-yellow catechins powder extracted from China tea by modem high new technique. According to the quality degree, the content of total catechins varies from 40% to 85%, It is higher than 70% in most products in which the content of total tea polyphenols is about 95-99%.
  In recent years, some countries, such as Japan, China, U.S.A., Germany, France and India etc., have done a great deal of research works concerning the pharmacological functions of catechines. It is confirmed that catechines have following special health-keeping efficacy:
  1. Prevent carcincgenicity, anti-mutagenicity and anti-tremor
  Catechines can conspicuously prevent and inhibit deformity, tumor and many kinds of cancer such as gullet cancer, duodenal cancer, colon cancer, gastric carcinoma, hepatocele, Skin cancer, and pancreas cancer induced by aflatoxin B1, benzo (α) pyrene, (+)-7β, 8α-dihydroxy-9α, 10α-epoxy-7,8,9,10-terrahydrobenxo (α)pyrene, 3-methylcholanthrene diethynitrosamine, nirous sodirm, N-nirroso-bis (2-oxoplopyl) amine and Geigiers. Catechins can also assuage the aftereffect of some anticancer chemical medicanments such as cis-diamminedichoro platinum(CDDP).
  2. Lowering blood pressure, hypolipidemic, anticoagulant and slimming effects
  Catechins can suppress the action of angiotensin I enzyme and reduce the concentrations of cholestrol, triglyceride and glucose in blood. So it can effectively prevent cardiovascular system disease and suppress adiposity caused by ingesting too many lipid.
  
3. Antioxidation and antiaging action
  Catechines is a kind of very effective antioxidant and cleaner of free bases, it can promote the activities of antioxiding enzyme system such as superoxide dismutase (SOD), glutathione peroxidase, and effectively prevent and inhibit the peroxidation of lipid to antiaging. It can be used as high performance natural antioxidant and anti-aging agent on cosmetics and health food.
  
4. Antibacterial action:
  Catechines can effectively inhibit many kinds of foodborne bacterial, such as Clostridirm botulinum, Staphylococcus aureus, C. prefringens, Bacillus cereus, Aeromonas sobria and Plesiomcns Shigelloids etc., and the activity of bacterial toxins such as Staphylococcus aureusα -toxin, Vibra parahaemolyticrs, Haemolysin, cholera toxin and cholera hemolysin, So, catechins can prevent and cure the disease induced by these bacterials or toxins.
  5. Preventing and curing cariosity, Deodorant activity.
  Catechines can not only disinfcct strcptococcus mutans, but also inhibit the glucosylase disenthralling from cariogenic baterials. So, it is remark-able efficacy of preventing and curing cariosity. Tea catechins have very strong deodorant activity (Especially against mouth odor, SH-compounds removal) which is better than synthesized chemicals, so, it is a very good raw material for manufacturing health tooth-paste and chewing gun.
  
6. Anti-AIDs
  Catechines (EGCG,ECG) are the strong inhibitors not only for Human Immunodeficiency Virus (HIV) reverse transcriptase but also for variouse DNA and RNA polymerases. So they can effectively prevent AIDS (Acquired Immune Deficiency Syndrome).
  Catechines are natural, multi-functional, marvelous health-keeping materials, which can used for prevent and cure above disease.
  Due to above described advantages of tea polyphenols used as food antioxidant, Japan and China have approved to use tea polyphenols as a new natural food additive, it is widely popularized now. Tea polyphenols is much better than synthetic antioxidant duo to its natural, high performance, non-toxiciy and proper price characters together with their healthcase effects.
