Abstract :

Antimicrobial formulations of plant origin are of great interest as certain antibiotics have undesirable effects while many lead to the development of multidrug resistance. The aim of the present work was to screen the antimicrobial potency of two locally collected green algae belonging to Chlorophyta from a water body in Ratnagiri (Maharashtra) and two commercially procured own algae Sargassum (sexual and vegetative forms). The algal samples were extracted using the Soxhlet extraction and methanol as a solvent. The methanolic extracts were tested against various Gram positive and Gram negative microorganisms using the well diffusion technique for antimicrobial assay. The study revealed that green algal extracts were more effective against Gram Positive organisms such as S.aureus, Bacillus spp. and more effective against Micrococcus spp. While the own algal extracts were effective against Gram Negative strains, none of the extracts could however inhibit Pseudomonas spp. The algal extracts were also subjected to HPTLC fingerprinting for detecting the presence of terpenes, coumarins and flavonoids, which will help in future to establish strong correlation of these phytoconstituents and their antimicrobial potency.
