antioxidant effects of ethyl acetate fraction of mentha spicata (l.) were evaluated against 4-nitroquinoline-1-oxide injected mice. for this study, experiment setup consisted of 36 albino mice of either sex divided into 6 groups: control (25% dmso in water), ethyl acetate fraction (eaf) alone group (80, 160 mg/kg body weight-bwt), 4-nqo (7.5 mg/kg bwt-ip) alone and 4-nqo + eaf. eaf and vehicles...

The influence of pulsed electric field (PEF) (0.5-2 kV/cm) treatment of wheatgrass (Triticum aestivum L.) seeds, with different water contents, on antioxidant metabolism in the resultant seedlings was investigated. Imbibing seeds to a water content of 45% or greater prior to PEF treatment increased the glutathione level and activities of superoxide dismutase, catalase, glutathione reductase, gl...

Many plants have been used to treat some diseases and infections since time immemorial, and this potential has been exploited by the pharmaceutical industry in the search of new analgesic, anticarcinogenic and antimicrobial agents, among other active agents. In order to contribute with bioprospection studies on the Colombian flora, 35 extracts from 13 plant species belonging to seven families (...

OBJECTIVE Alchornea floribunda leaves are widely used in ethnomedicine for the management of immuno-inflammatory disorders. We investigated the in vivo and in vitro antioxidant activity of the leaf extract, fractions and isolated compounds of A. floribunda. MATERIALS AND METHODS The ethyl acetate fraction of the methanol leaf extract was subjected to several chromatographic separations to iso...

Essential oil, ethanolic extract and decoction of 10 plant species from interior Portugal were analyzed for their activity towards acetylcholinesterase (AChE) enzyme and their antioxidant activity. Of these, Melissa officinalis, Paronychia argentea, Sanguisorba minor, Hypericum undulatum and Malva silvestris are used in herbal medicine, Laurus nobilis and Mentha suaveolens as condiments, and Sa...

Recent studies have demonstrated that marine sponges and their active constituents exhibited several potential medical applications. This study aimed to evaluate the possible hepatoprotective role as well as the antioxidant effect of the Red Sea Suberea mollis sponge extract (SMSE) on carbon tetrachloride- (CCl4-) induced acute liver injury in rats. In vitro antioxidant activity of SMSE was eva...

OBJECTIVES To examine levels of interleukin-6 (IL-6) in fertile semen donors and patients with varicocele and examine its association with semen characteristics and levels of reactive oxygen species (ROS). METHODS We conducted a prospective study consisting of 15 fertile donors (controls) and 35 infertile patients with varicocele. Semen analysis was performed according to the World Health Org...

Although it is well known that physical training ameliorates brain oxidative function after injuries by enhancing the levels of neurotrophic factors and oxidative status, there is little evidence addressing the influence of exercise training itself on brain oxidative damage and data is conflicting. This study investigated the effect of well-established swimming training protocol on lipid peroxi...

In the present study, the antioxidant and antiplasmodial activities of bergenin was compared with its natural derivative 11-O-galloylbergenin for the first time. Both compounds were isolated from Bergenia ligulata. 11-O-galloylbergenin was found to be very active in in-vitro antioxidant assay as compared to bergenin, which was found to be almost inactive. The EC50 values of 11-O-galloylbergenin...
