Antibacterial Activity and Extraction of Triterpenoid to lantana camara L. in Iraq

Abstract

Lantana camara belongs to the family Verbenaceae. This family consists of more than 100 genera and contains nearly 2600 species. Many of these species are of tropical or subtropical region. L. camara is cultivated as decorative plant or for making a boundary in a garden or field. Whole Lantana camara extracts are used to treat asthma, measles, and various types of cancer. The study aims to extract the triterpenoid within the plant lantana considering the environment in Iraq. Various separation methods based on temperature graduate were employed. Several solvents, including ethanol and hexane, were employed. The activity of triterpenoid as an antibacterial agent against a number of pathogenic species (Streptococcus pyogenes, Staphylococcus aureus, Escherichia coli, Klebsilla aeroganas). The disc diffusion method was used and the inhibition zones of different concentration were calculated. A triterpenoid extract was found very active against all type bacteria. Against Gram-positive Streptococcus pyogens, triterpenoid extract showed significant inhibition and weak inhibition against Gram-negative Escherichia coli.
