Antibacterial activities of Turkish pollen and propolis extracts against plant bacterial pathogens
Scopus
Toplam 118 atıf DOI
The "in vitro" antibacterial activities of Turkish pollen and propolis extracts were investigated against 13 different species of agricultural bacterial pathogens including Agrobacterium tumefaciens, A. vitis, Clavibacter michiganensis subsp. michiganensis, Erwinia amylovora, E. carotovora pv. carotovora, Pseudomonas corrugata, P. savastanoi pv. savastanoi, P. syringae pv. phaseolicola, P. syringae pv. syringae, P. syringae pv. tomato, Ralstonia solanacearum, Xanthomonas campestris pv. campestris and X. axonopodis pv. vesicatoria. Among the tested bacteria, A. tumefaciens was the most sensitive one to 1/5 concentration of pollen extract, and the sensitivity of the bacteria followed the sequence A. tumefaciens > P. syringae pv. tomato, X. axonopodis pv. vesicatoria > E. amylovora, P. corrugata, R. solanacearum, X. campestris pv. campestris > A. vitis, C. michiganensis subsp. michiganensis > E. carotovora pv. carotovora, P. savastanoi pv. savastanoi, P. syringae pv. phaseolicola > P. syringae pv. syringae. P. syringae pv. phaseolicola was the most sensitive one to 1/10 concentration of propolis extract, and the sensitivity of the bacteria followed the sequence P. syringae pv. phaseolicola > P. savastanoi pv. savastanoi, P. corrugata, R. solanacearum > E. carotovora pv. carotovora, P. syringae pv. syringae, E. amylovora, A. tumefaciens, A. vitis, C. michiganensis subsp. michiganensis, P. syringae pv. tomato, X. campestris pv. campestris, X. axonopodis pv. vesicatoria. The least active concentrations towards the tested bacteria were 1/100 of the pollen extract and 1/1000 of the propolis extract. This study is the first report on the antibacterial activities of pollen and propolis against the plant pathogenic bacteria. © 2005 Elsevier Ltd. All rights reserved.

The objective of the present work was to investigate the influence of locations on bioactive propertiest, phenolic compounds and mineral contents of bee pollens. The oil content of pollen grains changed between 3.50% (Alanya) and 6.85% (Russia-Perm Region). The highest total phenolic content (720 mg/100g) and antioxidant activity values (81.4%) were observed in pollens obtained from the Russia-Perm Region and Alanya districts, respectively. Additionally, the highest carotenoid was found in a pollen sample collected from Karaman (Sarıveliler) (98.6 mg/g). The major phenolic compounds were (+)-catechin (66.75-337.39 mg/100g) and quercetin (61.2-1221.7 mg/100g) in all pollen samples. The pollen samples were observed to be a significant source of potassium (3846-6287 mg/ kg), phosphorus (2947-5010 mg/kg), calcium (1022-2424 mg/kg) and sulfur (1744-2397 mg/kg). All of the analysis results were significantly affected by supplying locations. The antioxidant activity values of pollens were found partly similar and varied depending on locations. The content of saturated fatty acid (palmitic) was high (20-30%) in the tested pollen samples but did not exceed the content of linoleic acid.
