Author(s): S Thamizharasan, N Anbu Saravanan
Abstract: Marine mangrove plant Avicennia marina (AM), commonly called the grey or white mangrove, is a species of mangrove trees belonging to the Acanthaceae family. Traditionally it is used in to cure skin diseases against fish stings, ringworms, sores, boils, skin ulcers and scabies. It has also been used as a contraceptive and in treating rheumatism. In the literature, AM has been reported to exhibit antifertility, anticancer, antimicrobial and antitumor activities. Phytochemically, AM has been found to contain a variety of natural product groups, including naphthalene derivatives, flavones, glucosides, phenylpropanoid glycosides, abietane ditrerpenoid glycosides, flavonoid terpenoids and steroids. In the present study, methanolic crude extracts of the gray mangrove Avicennia marina leaf was evaluated for its antimicrobial activity. The results have shown that the extract attempt to inhibit the growth of Bacterial species Pseudomonas aeruginosa. The methanol extract of leaf has significant effect on bacterial strains with inhibition zones ranging from 17 to 21 mm respectively.
