	Azaleatin Azaleatin is a chemical compound. It is an O-methylated flavonol The O-methylated flavonoids or methoxyflavonoids are flavonoids with methylations on hydroxyl groups (methoxy bonds). O-methylation has an effect on the solubility of flavonoids. Enzymes O-methylated flavonoids formation implies the presence of spe ..., a type of flavonoid. It was first isolated from the flowers of '' Rhododendron mucronatum'' in 1956 and has since been recorded in forty-four other Rhododendron species, in '' Plumbago capensis'', in '' Ceratostigma willmottiana'' and in '' Carya pecan''. It has been also been found in the leaves of '' Eucryphia''. Glycosides Azalein is the 3-''O''-α-L- rhamnoside of azaleatin. References O-methylated flavonols Catechols {{Aromatic-stub ...

	Isorhamnetin Isorhamnetin is an O-methylated flavon-ol from the class of flavonoids. A common food source of this 3'-methoxylated derivative of quercetin and its glucoside conjugates are pungent yellow or red onions, in which it is a minor pigment, quercetin-3,4'-diglucoside and quercetin-4'-glucoside and the aglycone quercetin being the major pigments. Pears, olive oil, wine and tomato sauce are rich in isorhamnetin. Others sources include the spice, herbal medicinal and psychoactive Mexican tarragon ''(Tagetes lucida)'', which is described as accumulating isorhamnetin and its 7-O-glucoside derivate. Nopal (Opuntia ficus-indica (L.)) is also a good source of isorhamnetin, which can be extracted by supercritical fluid extraction assisted by enzymes. Metabolism The enzyme quercetin 3-O-methyltransferase uses S-adenosyl methionine and quercetin to produce S-adenosylhomocysteine and isorhamnetin. The enzyme 3-methylquercetin 7-O-methyltransferase uses S-adenosyl methionine and 5,7,3',4'-tetra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Nepetin Nepetin is the 6-Methoxy derivative of the pentahydroxyflavone 6-Hydroxyluteolin, an O-methylated flavone. It can be found in '' Eupatorium ballotaefolium''. Glycosides Nepitrin is the 7-glucoside of nepetin. References O-methylated flavones Catechols Resorcinols {{aromatic-stub ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Rhamnetin Rhamnetin is an O-methylated flavonol, a type of chemical compound. It can be isolated from cloves. The structure of the molecule was discovered by Austrian chemist Josef Herzig Josef Herzig (25 September 1853 – 4 July 1924) was an Austrian chemist. Herzig was born in Sanok, Galicia, which at that time was part of Austria-Hungary. Herzig went to school in Breslau until 1874, started studying chemistry at the U ... (1853–1924).
