    Green Tea Extract Product No.: OHI-000160 Active Ingredient: polyphenol

    catechins EGCG Specification: 99% Test Method UV-VIS Green Tea

    Extract Camellia sinensis (L.) Latin Names: Camellia sinensis (L.)

    Traditional Usage: Acute Breathing Disorders, Antibacterial, Anti-

    caries, Anti-inflammatory, Antioxidant, Antiseptic, Radiation Poisoning,

    Skin Disorders, Stimulant, Antispasmodic, Astringent, Breathing

    Disorders, Canker Sores, Cellular Regeneration,

    Tooth Decay (prevention), Ulcers (Peptic), Ultraviolet Radiation (Sun)

    Protection, Vascular Disorders Trial Clinical Study Results: To evaluate

    the anti-caries effect of green tea, a group of 150 volunteers were

    randomly divided into 3 groups: A, B and C with 50 persons in each.

    People in test groups A and B were given a green tea polyphenol tablet

    whereas placebo was given to group C (tablets were taken three times

    daily). After 3 weeks, group A was given placebo and group B continued

    with polyphenols for 6 weeks. After using polyphenol tablets for 2

    weeks, the plaque index of test groups were clearly lower than the

    control group (P < 0.01). After stopping use of the polyphenol

    tablet, the effect was still kept for 3 weeks. It can be concluded that

    polyphenol tablets from Chinese green tea have significant anti-plaque

    effect and can therefore help to prevent dental cavities. Active

    Constituents: Green and black tea leaves contain: methylxanthines -

    caffeine (theine), up to 4% with smaller amounts of theobromine and

    theophylline, as well as traces of adenine and xanthine; tannins.

    Polyphenols: tannins, mainly catechol tannins (10-20%); (-)-epicatechol,

    4-gallocatechol, epigallocatechin gallate (EGCG) and other catechol

    gallates; flavan-3-ols and flavan-3.4-diols, as well as dimeric thea-

    flavins and oligomeric proanthocyanidins (thearubigenins); phenolic

    carboxylic acids such as gallic and chlorogenic acids, etc. Flavour

    substances: alcohols (hex-3-en-1-ol, benzyl alcohol, and 2-phenyl-

    ethanol, as well as linalool in black tea and geraniol in green tea.);

    essential oils (monoterpene aldehydes and alcohols); and theanine, the

    5-ethylamide of glutamic acid. Other constituents: abundant flavonoids

    (including the apigenin derivatives isoschaftoside and vicenin-3);

    triterpenoid saponins; hydroperoxide lyases (anti-oxidant enzymes, and

    potent inhibitors of lipoxygenase). The accumulation of aluminum in tea

    leaves and the occasionally high content of fluorine compounds in older

    leaves are worth noting. Recent studies show that the residual green tea

    leaves remaining after tea is made are also rich in powerful

    antioxidants including (ranked according to suppressive activity against

    hydroperoxide generation): chlorophyll a > lutein > pheophytin a

    > chlorophyll b > beta-carotene > pheophytin b. [Wichtl and
