ABSTRACT

The Apocynaceae family plants have a variety of traditional uses, and it has practiced for a long time. Vallaris solanecea belongs to this family. This species is famous as an ornamental plant garden in Southeast Asia. The objective of this research is to estimate the antibiotic activity and the MIC in Vallaris solanecea specimens of chosen bacteria. The antibacterial properties in the samples were assessed against the bacterial pathogens – two gram-negative Salmonella typhi and Escherichia coli, also in terms of gram-positive Enterococcus faecalis activity. In this research of antimicrobial operation by the agar, well diffusion technique, petroleum-ether, chloroform and ethanol, and methanol and aqueous specimens were used. The antibacterial activity of samples was assessed around the wells to verify the microbial resistance. Results indicate that all the extracts were effective against tested organisms in comparison to standard drugs. Petroleum-ether and methanol extract exhibited a relatively higher zone of inhibition against S. typhi, E. coli, E. faecalis. Chloroform and ethanol extracts showed a satisfactory zone of inhibition against all the pathogens as compared to standard drug.
