Antimicrobial Activity of Mangrove Medicinal Plants

The book "Antimicrobial Activity of Mangrove Medicinal Plants" is the M.Sc Thesis/Dissertation... Mangrove plant extracts have been used for centuries as a popular method for treating several health disorders. Plant-derived substances have recently become of great interest owing to their versatile applications. In the present study, healthy leaves of Avicennia officinalis, Ceriops decandra and Acanthus ilicifolius were collected from the mangrove forest and the leaves were shade dried and powdered by hand crushing. The preparations of different leaves extract was done through modified method. Three different solvents viz., methanol, chloroform and ethyl acetate were used to study the antimicrobial activity of herbal plants. Disc diffusion method was adopted for evaluation of antimicrobial activity of three different mangrove medicinal plant leaves. The antimicrobial activity of methanol, chloroform and ethyl acetate leaf extract of Avicennia officinalis, Ceriops decandra and Acanthus ilicifolius were studied in different concentrations (100 mg/ml, 200 mg/ml, 300 mg/ml). Among the three concentrations (100 mg/ml, 200, 300 mg/ml) used, maximum inhibitory zone was observed at 300 mg/ml followed by 200 mg/ml and 100 mg/ml. No zone of inhibition was observed in the negative DMSO control. Among the three plants, maximum inhibition activity was exhibited by Acanthus ilicifolius followed by Ceriops decandra and Avicennia officinalis.
