ABSTRACT:The study describes the chemical and pharmacological investigations of propolis collected from Rasht region of Tajikistan. Total polyphenolic and total flavonoid contents resulted in propolis extract were: 0.49 mg gallic acid equivalents (GAE) and 0.11 mg quercetin equivalents (QE) per mg of dried extract, respectively. Chemical investigation of the ethanol extract delivered seven pure phenolic compounds identified as: quercetin (1), caffeic acid (2), ferulic acid (3), luteolin (4), kaempferol (5), apigenin (6) and rutin (7), respectively. Significant activity against Staphylococcus aureus and Candida albicans were shown by 70% ethanol extract of propolis (PE70), compounds 2 and 3. DPPH free radical scavenging assay yielded in powerful activity of PE70 with IC50 value 14.7±1.22 μg/mL while compounds 1, 3, 5, 7 resulted in IC50 values: 15.83±0.68 μM, 11.32±0.47 μM, 19.38±0.87 μM and 28.21±1.50 μM respectively. The PE70 and quercetin showed strongest antidiabetic activity with an IC50 7.52±0.21 and 7.54±0.19 μg/mL, respectively. Literature clarified that this is the first report presenting the results regarding the propolis from Tajikistan.
