Comparative Evaluation of Antibacterial Properties and Phytochemical Profile of Selected Mangrove Plants from Bhitarkanika, India

Abstract

Different solvent extacts of Mangrove plants (Avicennia alba, Avicennia marina, Phoenix paludosa and Acanthus ilicifolius) from Bhitarkanika were evaluated for their antibacterial properties and phytochemical constituents. The phytochemicals profiling showed that the plants are rich source of secondary metabolites like saponin (6-14.0 %), tannin (2.22-.45 %) and phenol (1.07-1.82 %) etc. Among the mineral content, carbohydrate (10.46 %), nitrogen (1.79 %) and potassium dioxide (1.068 %) tops the table. Selective screening and evaluation of minimum inhibitory concentrations (MIC) of the different plant extracts (acetone, ethanol, methanol and aqueous) showed that the true mangroves species of A. alba and A. marina exhibits potent antibacterial properties against the nine human pathogens whereas the mangrove associated species of P. paludosa and A. ilicifolius though contains high level of minerals and vitamins are not a reliable antimicrobial source. The phytochemicals present in the plant extracts may contribute to their uses as a source of antimicrobial drugs / agent in near future.

Synthesis of silver nanoparticles using Lactobacillus bulgaricus and assessment of their antibacterial potential

“…Few biomimetic approaches have been established that are ecological and sustainable for the synthesis of nanoparticles. One of the fundamental processes in biomimetic is the bio-reductive process via microorganisms, enzymes, fungi, plants, and/or plant extracts (Patra et al, 2014;Klueh et al, 2000). For centuries, silver has been used for the treatment of burns, chronic wounds, venereal disease, fistulae from slivery glands, bone and perianal disease, and numerous bacterial infections.…”

Antimicrobial and Antioxidant Property of a True Mangrove Rhizophora apiculata Bl.

“…), skin problems (dermatitis, itching, scabies, rash, wounds, scar, moles), goitre, and diabetes have all been treated with H. fomes plant parts. [22][23][24] Rhizophora trees are believed to have therapeutic qualities in traditional remedies. Root, leaf, and stem extracts from Rhizophora trees contain inhibitory effects that affect the growth of several human pathogenic bacteria.…”
