Rutin (quercetin-3-O-rutinoside) is a multifunctional natural flavonoid glycoside with profound effects on the various cellular functions under pathological conditions. Due to the ability of rutin and/or its metabolites to cross the blood brain barrier, it has also been shown to modify the cognitive
Chromatographic fractionation of the alcoholic extract of the dried fronds of Adiantum capillus-veneris L. (Adiantaceae) yielded seven compounds: four triterpenoidal compounds belonging to adiantane and filicane groups were isolated from the hexane fraction and identified as isoadiantone (1);
BACKGROUND
In recent years, flavonoids have been revealed to be helpful in the treatment of many diseases. Rutin (3,3',4',5,7-pentahydroxyflavone-3-rhamnoglucoside) is an important flavonoid that is consumed in the daily diet. It is also known as vitamin P and quercetin-3-O-rutinoside. In addition,
