Theasinensin D is polyphenol flavonoid found in oolong tea. It's an atropisomer of theasinensin A.
Oolong is a traditional semi-oxidized Chinese tea produced through a process including withering the plant under strong sun and oxidation before curling and twisting. Most oolong teas, especially those of fine quality, involve unique tea plant cultivars that are exclusively used for particular varieties. The degree of oxidation, which varies according to the chosen duration of time before firing, can range from 8 to 85%, depending on the variety and production style. Oolong is especially popular in south China and among Chinese expatriates in Southeast Asia as is the Fujian preparation process known as the Gongfu tea ceremony.
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 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 and Southeast Asia.
Flavonoids are a class of polyphenolic secondary metabolites found in plants, and thus commonly consumed in the diets of humans.
Rutin, also called rutoside, quercetin-3-O-rutinoside and sophorin, is the glycoside combining the flavonol quercetin and the disaccharide rutinose. It is a citrus flavonoid found in a wide variety of plants including citrus.
Lotaustralin is a cyanogenic glucoside found in small amounts in Fabaceae austral trefoil, cassava, lima bean, roseroot and white clover, among other plants. Lotaustralin is the glucoside of methyl ethyl ketone cyanohydrin and is structurally related to linamarin, the acetone cyanohydrin glucoside also found in these plants. Both lotaustralin and linamarin may be hydrolyzed by the enzyme linamarase to form glucose and a precursor to the toxic compound hydrogen cyanide.
Yuremamine is a phytoindole alkaloid which was isolated from the bark of Mimosa tenuiflora in 2005, and erroneously assigned a pyrrolo[1,2-a]indole structure that was thought to represent a new class of indole alkaloids. However, in 2015, the bioinspired total synthesis of yuremamine revealed its structure to be a flavonoid derivative. It was also noted in the original isolation of yuremamine that the alkaloid occurs naturally as a purple solid, but total synthesis revealed that yuremamine as a free base is colorless, and the formation of a trifluoroacetate salt during HPLC purification is what led to the purple appearance.
Demexiptiline is a tricyclic antidepressant (TCA) used in France for the treatment of depression. It acts primarily as a norepinephrine reuptake inhibitor similarly to desipramine.
The phenolic content in tea refers to the phenols and polyphenols, natural plant compounds which are found in tea. These chemical compounds affect the flavor and mouthfeel of tea. Polyphenols in tea include catechins, theaflavins, tannins, and flavonoids.
Lambertianin D is an ellagitannin found in Rubus lambertianus.
Iris bungei is a beardless iris in the genus Iris, in the subgenus Limniris and in the series Tenuifoliae of the genus. It is a rhizomatous herbaceous perennial, from Mongolia, Tibet and China. It has green leaves, short stem and 2 violet, purple, lavender or blue flowers.
Streptomyces xanthophaeus is a bacterium species from the genus of Streptomyces which has been isolated from soil. Streptomyces xanthophaeus produces geomycin, arginylthreonine and diadzein.
Mirificin, also known as daidzein 8-C-(6-apiofuranosylglucoside), is an isoflavone that is found in Pueraria mirifica and Pueraria lobata. It has estrogenic activity and hence is a phytoestrogen.
Kabuse tea, or kabusecha (かぶせ茶) is a class of Japanese tea leaf. Kabuseru (かぶせる) literally means to cover or place on top, as a hat on a head, therefore kabuse tea is a tea leaf harvested from a tea plant that, for some period of time ranging from 2–25 days, has had a porous material draped over the plant while the young leaves are being produced. Kabuse tea is almost exclusively a first flush tea. Though kabuse tea is usually processed into a green tea after picking, kabuse tea denotes a pre-picking process and the freshly picked leaf can be used to produce any kind of tea, from green tea to oolong tea to black tea, etc.
Haliangium is a genus of bacteria from the family of Kofleriaceae. Haliangium bacteria produce the antifungal compounds haliangicins.
Theasinensin A is polyphenol flavonoid from black tea created during fermentation, by oxidation of epigallocatechin gallate.
Theasinensin B is polyphenol flavonoid from black tea.
Theasinensin C is polyphenol flavonoid from black tea.
Theasinensin E is polyphenol flavonoid found in oolong tea. It's an atropisomer of theasinensin C.
Theasinensin F is polyphenol flavonoid found in oolong tea.
Theasinensin G is polyphenol flavonoid found in oolong tea.
