Phytochemical study of some active principles with antioxidant action from the Rosmarinus officinalis and Salvia officinalis species

Many natural products have been reported to contain large amounts of antioxidants other than vitamin E, C, carotenoids (Javanmardi et al., 2003). These antioxidants play a role in delaying, intercepting, or preventing oxidative reaction (Vilioglu et al., 1998) catalysed by free radicals. This antioxidant activity may be mainly do to the present of phenolic components such as flavoinoids (Pietta,1998), phenolic acids and phenolic diterpenes (Shahidi et al., 1992). It is necessary to find out if medicinal plants could provide the antioxidant substances that may help to modulate oxidative stress who are associated with many pathological disorders. This phytochemical study emphasized the existence of some compounds with antioxidant action flavon and poliphenol types in hydroalcoholic extracts of Salvia officinalis and Rosmarinus ofiicinali

Some cytogenetic effects induced in barley by the treatments with hydroalcoholic rosemary extract

The paper presents some results regarding the cytogenetic effects induced in barley by the treatments with rosemary extract (Rosmarinus officinalis). It was proved that the treatment with this extract upon the barley caryopses had as effect the stimulation of the mitotic division in the radicle apex of the species and did not lead to important cytogenetic changes (chromosome aberrations) in the ana-thelophase of the radicle mitoses
