Abstract:
The presence of pollen grains of various species in honey were assumed to have antimicrobial activity. Based on this assumption, present investigation on antimicrobial potential of two local species of family Rosaceae namely Prunus domestica L. and Rosa indica L. were carried out. For this purpose three solvent extracts of pollen grains of both the species viz. Petroleum ether, chloroform and methanol extracts were tested against three types of Gram positive bacteria (Bacillus subtili, Microcococcus lutea, and Staphylococcus aureus),. One type Gram negative bacterial (Escherichia coli) and one type of fungus (Aspergillus niger). Their zones of inhibition were measured and compared with standard drug. Various physical parameters and chemical identification tests were undertaken to know the nature of active phytochemical compounds present in these extracts and the possible relationship with their antimicrobial activity. Both types of pollen grains indicated distinct antimicrobial potential. Petroleum ether extracts of both types of pollen grains showed well-marked antifungal activity and lesser antibacterial potential than standard disc. Whereas chloroform and methanol extracts of both types of pollen grains exhibited marked antibacterial properties but not antifungal when compared with standard drug.
