Abstract :
Introduction: The role of medicinal plants in enhancement of memory and improvement of
Alzheimer disease symptoms has attracted researchers’ attention. Genus Salvia (sage) is the
largest and most valuable type of herbal medicine from Lamiaceae family, and its therapeutic
effects have long been considered. This study investigated the effect of hydroalcoholic
extract of Salvia officinalis (S. officinalis) leaves on scopolamine-induced amnesia in adult
male mice.
Materials and methods: A step-through inhibitory avoidance task was used for memory
assessment. Animals received hydroalcoholic extract of Salvia (10, 20 or 40 mg/kg) 30
minutes after administration of scopolamine (1 mg/kg, intraperitoneally) after training and
before testing, (based on experimental design). Animals were tested 24 h after the training
session, and step-through latency in entering the dark compartment was recorded as passive
avoidance memory. The data were analyzed by one-way ANOVA, followed by Tukey test.
Statistical significance level was set at P<0.05.
Results: The results indicated that administration of scopolamine impaired both
consolidation and retrieval of passive avoidance memory. Administration of 40 mg/kg
hydroalcoholic extract of Salvia after training, or 20 and 40 mg/kg on the day of experiment
ameliorated the effect of scopolamine.
Conclusion: The hydroalcoholic extract of Salvia can inhibit scopolamine-induced
impairment of passive avoidance memory in mice.
