Kohki Tea

	Kohki Tea Kohki tea (黄杞茶) or ''Huang Qi Tea'' is a Chinese/Japanese herbal drink very high in antioxidant activity. Kohki tea has been sold over the counter for centuries and is standardized to contain astilbin and taxifolin Taxifolin (5,7,3',4'-flavan-on-ol), also known as dihydroquercetin, belongs to the subclass flavanonols in the flavonoids, which in turn is a class of polyphenols. Stereocenters Taxifolin has two stereocenters on the C-ring, as opposed to quer .... Astilbin can be isolated from Kohki tea processed from '' Engelhardtia chrysolepis'' (huang-qi).

	Astilbin Astilbin is a flavanonol, a type of flavonoid. Astilbin is the (2R-trans)-isomer; neoisoastilbin is the (2S-cis)-isomer and isoastilbin is the (2R-cis)-isomer. Natural occurrences Astilbin can be found in St John's wort (''Hypericum perforatum'', Clusiaceae, subfamily Hypericoideae, formerly often considered a full family Hypericaceae), in '' Dimorphandra mollis'' (Fava d'anta, Fabaceae), in the leaves of ''Harungana madagascariensis'' (Hypericaceae), [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Taxifolin Taxifolin (5,7,3',4'-flavan-on-ol), also known as dihydroquercetin, belongs to the subclass flavanonols in the flavonoids, which in turn is a class of polyphenols. Stereocenters Taxifolin has two stereocenters on the C-ring, as opposed to quercetin which has none. For example, (+)-taxifolin has (2R,3R)-configuration, making it 1 out of 4 stereoisomers that comprise 2 pairs of enantiomers. Natural occurrences Taxifolin is found in non-glutinous rice boiled with adzuki bean (adzuki-meshi). It can be found in conifers like the Siberian larch, ''Larix sibirica'', in Russia, in ''Pinus roxburghii'', in ''Cedrus deodara'' and in the Chinese yew, '' Taxus chinensis var. mairei''. It is also found in the silymarin extract from the milk thistle seeds. Taxifolin is present in vinegars aged in cherry wood. Taxifolin, and flavonoids in general, can be found in many beverages and products. Specifically, taxifolin is found in plant-based foods like fruit, vegetables, wine, tea, and coco ...

picture info	Japanese Tea Green tea is a type of tea that is made from ''Camellia sinensis'' leaves and buds that have not undergone the same withering and oxidation process which is used to make oolong teas and black teas. Green tea originated in China, and since then its production and manufacture has spread to other countries in East Asia. Several varieties of green tea exist, which differ substantially based on the variety of ''C. sinensis'' used, growing conditions, horticultural methods, production processing, and time of harvest. The two main components unique to green tea are "catechins" and "theanine," and the health effects of these components are attracting a great deal of attention in Japan and abroad. History Tea consumption has its legendary origins in China during the reign of mythological Emperor Shennong. A book written by Lu Yu in 618–907 AD (Tang dynasty), ''The Classic of Tea'' (), is considered important in green tea history. The ''Kissa Yōjōki'' (喫茶養生記 ''Book of ...
