Flavonols and flavones of parsley cell suspension culture change the antioxidative capacity of plasma in rats

The flavonoid aglycones from an illuminated parsley (Petroselinum crispum ( Mill.) Nym.) cell suspension culture were identified and quantified as the flavones apigenin, luteolin and chrysoeriol and the flavonols kaempferol, q uercetin and isorhamnetin. Flavonoid extracts from these cultures were puri fied by solid phase extraction from RPC-18 phase and given by gavage to rat s. Only extract from illuminated culture increased the antioxidative capaci ty (AOC) of blood plasma temporarily with maximum values after 1 h. It is c oncluded that the course of AOC reflects changes in the plasma content of f lavonoids.
