Thirty-two samples of chocolate products were analysed by HPLC for caffeine and theobromine contents. Defatted residues of samples were extracted with 80% aqueous acetone. After extraction into boiling water, the methylxanthines were identified and quantified with the use of μ-Bondapak column and mobile phase of methanol:water:acetic acid (20:79:1). Levels of caffein and theobromine in 32 sampl...

Caffeine, dose dependently can reinforce or deteriorate learning. In previous studies, the effect of glucose on decreasing of amnesia was investigated. In this study, the effect of caffeine on three phases of learning and also probable interference of glucose in mice were examined by using of passive avoidance learning .Male albino mice were examined as follows: 1. test group: a) this group rec...
