Neoflavonoids are a class of polyphenolic compounds. While flavonoids have the 2-phenylchromen-4-one backbone, neoflavonoids have the 4-phenylchromen backbone with no hydroxyl group substitution at position 2.
Myricitrin is a plant compound, the 3-O-α-L-rhamnopyranoside of myricetin.
Neohesperidose is the disaccharide which is present in some flavonoids. It can be found in species of Typha.
Europinidin (Eu) is an O-methylated anthocyanidin. It is a water-soluble, bluish red plant dye. It is a rare O-methylated flavonoid, a derivative of delphinidin. It can be found in some species of Plumbago and Ceratostigma.
Aromadendrin is a flavanonol, a type of flavonoid. It can be found in the wood of Pinus sibirica.
Caftaric acid is a non-flavonoid phenolic compound.
Iridin is an isoflavone, a type of flavonoid. It is the 7-glucoside of irigenin and can be isolated from several species of irises like orris root, Iris florentina or Iris versicolor, also commonly known as the larger blue flag. It can also be found in Iris kemaonensis.
The O-methylated flavonoids or methoxyflavonoids are flavonoids with methylations on hydroxyl groups. O-methylation has an effect on the solubility of flavonoids.
Epicatechin gallate (ECG) is a flavan-3-ol, a type of flavonoid, present in green tea. It is also reported in buckwheat and in grape.
Prenylated flavonoids or prenylflavonoids are a sub-class of flavonoids. They are widely distributed throughout the plant kingdom. Some are known to have phytoestrogenic or antioxidant properties. They are given in the list of adaptogens in herbalism. Chemically they have a prenyl group attached to their flavonoid backbone. It is usually assumed that the addition of hydrophobic prenyl groups facilitate attachment to cell membranes. Prenylation may increase the potential activity of its original flavonoid.
Asplenium antiquum is a fern of the group known as bird's-nest ferns. In Japanese it is known by ō-tani-watari and tani-watari.
Eupatolitin is a chemical compound. It is an O-methylated flavonol, a type of flavonoid. Eupatolitin can be found in Brickellia veronicaefolia and in Ipomopsis aggregata.
Flavonolignans are natural phenols composed of a part flavonoid and a part phenylpropane.
Syringetin is an O-methylated flavonol, a type of flavonoid. It is found in red grape, in Lysimachia congestiflora and in Vaccinium uliginosum. It is one of the phenolic compounds present in wine.
Luteone is a prenylated isoflavone, a type of flavonoid. It can be found in the pods of Laburnum anagyroides and can be synthesized.
Quercetagetin is a flavonol, a type of flavonoid. It can be found in the genus Eriocaulon.
Elaeocarpus lanceifolius is a tree species in the family Elaeocarpaceae. It is found across tropical Asia from Thailand to Yunnan to Nepal to Karnataka, India. It is used for its wood, fruit, and nuts.
The pomegranate ellagitannins, which include punicalagin isomers, are ellagitannins found in the sarcotestas, rind (peel), bark or heartwood of pomegranates.
Hypolaetin is a flavone. It is the aglycone of hypolaetin 8-glucuronide, a compound found in the liverwort Marchantia berteroana. Hypolaetin 8-glucoside can be found in Sideritis leucantha.
Persicarin is a sulfated flavonoid naturally found in the cells of several plant species, including the water dropwort. It was first isolated from water pepper in 1937 by Jeffrey Harborne. The name of persicarin is derived from the Latin name of the plant: Persicaria hydropiper. It is also found in dill and because it is then excreted into urine, that makes persicarin a potential biomarker for the consumption of this food. Persicarin has been reported to show some promising results in protecting against and treating type 1 diabetes-induced liver inflammation and damage in mice models.
