| Abstract: | Marine ascidians contain antibacterial
agents of relevance to either antifouling technology or clinical pharmacology. In the present
study two ascidians Polyandrocarpa indica and Phallusia arabica were
examined for their antibacterial activity against ten bacterial pathogens. Antimicrobial activity of the crude extract of
ascidians shows inhibitory activity against almost all the strains. However,
methnolic extract of P. arabica shows prominent antibacterial activity against than that of
P. indica. Maximum inhibition zone (17 mm) was observed against Salmonella
typhi in the crude methanol extract of
P. arabica and the minimum inhibition zone (1 mm) was noticed against P. mirabilis and P. aeruginosa in the ethyl acetate and diethyl ether extract
of P. indica. In P. indica the crude extract range of inhibition of bacteria varied
from 1-12 mm.
Based on observed zone of inhibition, present study revealed that P. arabica extract
are more effective than P. indica. |
