An infusion prepared with aerial parts from Galphimia glauca has been widely used in Mexican traditional medicine as a remedy for nervous excitement. The sedative activity of a methanolic extract from this plant has been demonstrated by neuropharmacological tests. This effect was attributed to the nor-secotriterpene named galphimine B (GB). In the present work, the anxiolytic and antidepressant-like effects of G. glauca methanolic extract (standardized on GB content, 8.3mg/g) were assayed by using the elevated plus-maze, light-dark test and the forced swimming paradigm, on ICR albino mice. This extract, administered orally, three times (24, 18 and 1h before the test), and in different doses (125, 250, 500, 1,000 and 2,000 mg/kg) was able to increase significantly (p<0.05) the number of entries, as well as the time spent in the open arms of the elevated plus-maze, indicating an anxiolytic-like effect. A similar effect was observed in the light-dark paradigm test, the time spent in the light box was increased in treated mice. Nevertheless, this treatment was unable to change any parameter in the forced swimming test. Altogether, these results suggest an anxiolytic-like effect to the methanolic standardized extract of G. glauca on ICR inbred mice.
