Summary: | Valeriana officinalis
L. (Valerian) is widely used as a traditional medicine to improve the quality of sleep. Although
V. officinalis
have been well documented as promising pharmacological agent; the exact mechanisms by which this plant act is still unknown. Limited literature data have indicated that
V. officinalis
extracts can exhibit antioxidant properties against iron in hippocampal neurons in vitro. However, there is no data available about the possible antioxidant effect of
V. officinalis
against other pro-oxidants in brain. In the present study, the protective effect of
V. officinalis
on lipid peroxidation (LPO) induced by different pro-oxidant agents with neuropathological importance was examined. Ethanolic extract of valerian (0–60 μg/ml) was tested against quinolinic acid (QA); 3-nitropropionic acid; sodium nitroprusside; iron sulfate (FeSO
4
) and Fe
2+
/EDTA induced LPO in rat brain homogenates. The effect of
V. officinalis
in deoxyribose degradation and reactive oxygen species (ROS) production was also investigated. In brain homogenates,
V. officinalis
inhibited thiobarbituric acid reactive substances induced by all pro-oxidants tested in a concentration dependent manner. Similarly,
V. officinalis
caused a significant decrease on the LPO in cerebral cortex and in deoxyribose degradation. QA-induced ROS production in cortical slices was also significantly reduced by
V. officinalis
. Our results suggest that
V. officinalis
extract was effective in modulating LPO induced by different pro-oxidant agents. These data may imply that
V. officinalis
extract, functioning as antioxidant agent, can be beneficial for reducing insomnia complications linked to oxidative stress. |
