In vitro antimicrobial activity of two selected marine macroalgae has been evaluated in the present
research, which lies in identifying certain seaweeds whose extract can act as an alternative to commonly used
antibiotics hence possessing activity against human pathogens. Extract from two species of seaweed samples
namely Caulerpa racemosa and Grateloupia lithophila were collected from different locations at Gulf of
Mannar, Southeast Coastal Region, M andapam, Tamil Nadu, India and w ere screened for antimicrobial activity.
Extracts of Methanol, Ethanol, Butanol, Acetone, Chloroform and Dichloromethane were tested against selected
human pathogens. Both the seaweeds collected had shown moderate antibacterial activity with <15 mm of zone
of inhibition. Out of which only butanolic extract of has shown significant activity. Phytochemical screening
revealed the presence of alkaloid and phenolic compounds in both the seaweeds whereas flavonoids and
steroids were found to be present in only Caulerpa racemosa. The screening result confirms that these seaweeds
can be further studied and used as possible source of antimicrobial compounds.
Key words: Alkaloids, antimicrobial activity, flavonoids, phytochemical analysis, , ,
