Antibacterial Potential

The current study reveals the pharmacological and phytochemical potential of different solvent fractions of Ifloga spicata. Antimicrobial and free radical scavenging activities, DPPH (1, 1-diphenyl-2-picrylhydrazyl), hydrogen peroxide scavenging assay, and cytotoxic effects of plant samples on lymphocytes stressed with hydrogen were performed. Ifloga spicata ethyl acetate fraction markedly showed higher antibacterial potential against P. aeruginosa (ATCC 27853) and E. Coli (ATCC 25922) bacteria. While higher antifungal potential was shown by the chloroform fraction against all three different a strain A. fumigates (ATCC 204305), A. flavus (ATCC 9643) and A. niger (ATCC 16404) as compared to others fractions of sample. DPPH maximum antioxidant potential was noted for methanolic extract followed by ethyl acetate and chloroform. Similarly, hydrogen peroxide effect was significantly decreased by ethyl acetate fraction. In blood lymphocytes the raise in ROS and TBARS level due to stress given by H2O2 was also recovered by different extracts of I. spicata. The decrease level of CAT, SOD and POD was also restored

Rosa Species

The fruit of Rosa multiflora has been used as traditional herbal medicine in Asian countries. The present investigation was undertaken to study the antimicrobial activity and total polyphenol content of hexane, ether, ethyl acetate, water fraction of methanol extract of fruit and flower from Rosa multiflora and Rosa wichuraiana. Antimicrobial activity of the mentioned fractions against 3 gram-positive and 4 gram-negative bacteria using disk diffussion method. The measurement of minimal inhibition concentration (MIC) showed that the ethyl acetate fraction of the two Rosa species is the most effective against the tested bacteria. The total polyphenol content of ethyl acetate fraction of the two Rosa species is higher than the other fractions. The results indicate the antimicrobial activity was related with the total polyphenol content and the fruit and flower of the two Rosa species can be considered as a natural source of antimicrobial agents.
