The effect of palm date, fig and olive fruits regimen on weight, pain threshold and memory in mice

Fruit of date Palm (Phoenix dactylifera L.) is very commonly consumed, especially in Arabic countries. This fruit has important pharmacologic properties such as antioxidant and antimutagenic effects. Fig (Ficus carica L.) shows highly efficient antioxidant and antimutagenic activity as well and produces a significant increase in plasma antioxidant capacity for 4 hours after consumption. Olive (Olea europaea L.) with polyphenols has potent antioxidant and anti-inflammatory properties. In this study due to antioxidant and antimutagenic activity in date, fig and olive fruits are quite potent, we investigated the effects of these fruits on weight, pain threshold and memory in day regimen of mice. We used hot plate to study pain threshold and also the passive avoidance apparatus for measurement of memory 24 hours in mice was step down. Our results showed that, these fruits significantly increase memory and do not affect weight and pain threshold.
