Pyranoflavonol
The pyranoflavonoids are a type of flavonoids possessing a pyran group. Cyclocommunin is another natural pyranoflavonoid. Pyranoanthocyanins Pyranoisoflavones * Alpinumisoflavone * Di-O-methylalpinumisoflavone * 4'-methyl-alpinumisoflavone * 5,3′,4′-trihydroxy-2″,2″-dimethylpyrano (5″,6″:7,8) isoflavone - has antifungal properties, and is from the plant species ficus tikoua Bur. The enzyme monoprenyl isoflavone epoxidase produces a dihydrofurano pyranoisoflavone derivative from 7-O-methylluteone.

Millettia Pinnata
''Millettia pinnata'' is a species of tree in the pea family, Fabaceae, native to eastern and tropical Asia, Australia, and Pacific islands. It is often known by the synonym ''Pongamia pinnata''. Its common names include Indian beech and Pongame oiltree. Description ''Millettia pinnata'' is a legume tree that grows to about in height with a large canopy that spreads equally wide. It may be deciduous for short periods. It has a straight or crooked trunk, in diameter, with grey-brown bark, which is smooth or vertically fissured. Branches are glabrous with pale stipulate scars. The imparipinnate leaves of the tree alternate and are short-stalked, rounded, or cuneate at the base, ovate or oblong along the length, obtuse-acuminate at the apex, and not toothed on the edges. They are a soft, shiny burgundy when young, and mature to a glossy, deep green as the season progresses, with prominent veins underneath. Flowering generally starts after 3–4 years with small clusters of whit ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Flavonols
Flavonols are a class of flavonoids that have the 3-hydroxyflavone backbone (IUPAC name : 3-hydroxy-2-phenylchromen-4-one). Their diversity stems from the different positions of the phenols, phenolic hydroxyl, -OH groups. They are distinct from flavanols (with "a") such as catechin, another class of flavonoids. Flavonols are present in a wide variety of fruits and vegetables. In Western populations, estimated daily intake is in the range of 20–50 mg per day for flavonols. Individual intake varies depending on the type of diet consumed. The phenomenon of dual fluorescence (due to excited state intramolecular proton transfer or ESIPT) is induced by tautomerism of flavonols (and glucosides) and could contribute to plant UV protection and flower colour. Besides being a subclass of flavonoids, flavonols are suggested by a study of cranberry juice to play a role along with proanthocyanidins, in the juice's ability to block bacterial adhesion, demonstrated by the compressing the ...
