ABSTRACT

To study the antimicrobial activity of Lantana Camara. Linn, and its isolated constituent and also to find phytochemical constituents. The leaves of the plant under study was collected and processed for hot extraction by soxhlet apparatus using ethanol and water as solvents. From the qualitative analysis phytochemical evaluation revealed the presence of flavanoids, triterpenoids, alkaloids, and volatile oils. Its antimicrobial sensitivity testing was detected by measuring the zone of inhibition of different bacterial culture using disc plate method. Alcohol extract showed more antibacterial activity than water extract, against E.coli Bacillus aureus, Pseudomonas auroginosa, and Staphylococcus aureus. Among them these extracts have more antimicrobial activity towards E.coli. When compared with the standard gentamycin, the extract showed comparable antimicrobial activities. Phytochemical studies indicates that the presence of flavanoids, volatile oils, triterpenoids, alkaloids, and carbohydrates. Presence of triterpenoids may be responsible for the antibacterial activity. Large scale production of active constituents of Lantana Camara. Linn would be an advantageous for natural, herbal antimicrobial agents. 

Key words:  Arippu, Triterpenoids, Spanish flag, Lantana Camara. Linn
