ABSTRACT:

In India Avicennia officinalis is commonly used for herbal preparations in the treatment of small pox sores, scabies, as a contraceptive, boils and tumors. This has, therefore, led to the investigation of the antimicrobial activities of methanolic extract of A. officinalis. Eighteen different bacterial and fungal belonging to clinical and plant pathogenic microorganisms were used. The results show that A. officinalis extracts exhibited antimicrobial activities at a concentration of 20 mg/mL. Antibacterial activity of mature leaves and bark extracts of A. officinalis was evaluated using soxhelt extraction method. Hexane, chloroform and methanol were used as solvents in order to get the plant extracts. The antibacterial activity was screened by using agar well diffusion technique against human and plant pathogenic bacteria and fungi. The length of inhibition zone was measured in millimeters from the edge of the well to the edge of the inhibition zone. Mature leaf extracts of A. officinalis in methanol exhibited promising antimicrobial activity than other solvent extracts. Phytochemical screening revealed that mature leaf of A. officinalis contained alkaloids, steroids, triterpenoids and flavonoids.
