Anxiolytic property of hydro-alcohol extract of Lactuca safiva and its effect on behavioral activities of mice

Lactuca sativa, belonging to the Asteraceae family, is a leafy vegetable known for its medicinal properties. This study aimed to understand the mechanism of Lactuca sativa extract with respect to pharmacological action. We investigated the anxiolytic effects of hydro-alcoholic extract of leaves of Lactuca sativa on mice. The behav- ioral tests performed on mice models to assess anti-anxiety properties were： open field test （OFT）, elevated plus maze test （EPM）, elevated T maze test, and marble burying test. Increased locomotor activity and time spent in the ＂open-ann＂ were observed in extract fed group. Malondialdehyde （MDA） and nitrite levels were decreased, cata- lase and glutathione levels were increased in Lactuca sativa treated mice. The data obtained in the present study suggests that the extract of Lactuca sativa can afford significant protection against anxiolytic activity.
