Polyphenols (Tea Polyphenols) is tea polyphenols in general, including flavanols, anthocyanins, flavonoids, flavonols and phenolic acids and the like. Mainly flavanol (catechin) type, accounts for 60 to 80% catechin. Substances known as polyphenols or tannin tea tea tannin, is one of the main ingredients of tea color, flavor formation, but also one of the main ingredients in tea health functions. Studies have shown that polyphenols and other active substances with detoxification and anti-radiation effect, can effectively prevent radioactive substances invade the bone marrow, and strontium 90 and cobalt-60 can rapidly excreted, the health and medical profession as "radiation nemesis."

Hesperetin is a bioflavonoid and, to be more specific, a flavanone. Hesperidin (a flavonone glycoside) is water-soluble due to the presence of the sugar part in its structure, so on ingestion it releases its aglycone. Although not as juicy or delicious as the inside of an orange, the peel is edible, and has been consumed particularly in environments where there is scarcity of resources and where maximum nutritional value must be derived and minimal waste generated (for example, on a submarine). The peel of an orange has increased vitamin C and fiber. Most of the vitamin C is located in the zest rather than the pith. However, high concentrations of pesticides have been found in orange peels.Some organizations recommend that one should only consume the peels of organically grown and processed oranges, where chemical pesticides or herbicides would not have been used on the peel.Orange peel contains citral, an aldehyde that antagonizes the action of vitamin A. Therefore, anyone eating orange peels should make certain that their dietary intake of Vitamin A is sufficient.
Rhubarb is a group of plants that belong to the genus Rheum. They are herbaceous perennial plants growing from short, thick rhizomes. They have large leaves that are somewhat triangular-shaped with long fleshy petioles.They have small flowers grouped in large compound leafy greenish-white to rose- red inflorescence. The active ingredient of rhubarb is chrysophanol / chrysophanic acid which impart cathartic and laxative properties. It is hence useful as a cathartic in case of constipation.
Daidzein has both weak estrogenic and weak anti-estrogenic effects. Daizein has also antioxidant activity. Foti P. et al of the Department of Food Science and Microbiology (University of Milan) compared the antioxidant activity daidzein and genistein. antioxidant activity in primary and cancer lymphocytes. Their results showed that daidzein is just as effective as genistein in protecting cells against oxidative damage of DNA. The antioxidant activity of daidzein was measured at concentration which could be obtained by consumption of soy products.
Apple rich in many minerals, such as carbohydrate, protein, fat, vitamin C, pectin, tannins, organic acid and calcium, phosphorus, iron, potassium and other minerals. Apple always valued by people because of its high nutritions. It has been used for rule out the salt and beauty&skin care, lower blood pressure and so on. Besides, apple polyphenol have a function that anti-oxidation and have a prevention prevention of high blood pressure and allergic reaction. So , apple extract can be used in the manufacture of health food and cosmetics.
