For a long period of time in history mangrove plant extracts have been used for various producing a wide array of novel products. Plant-derived substances have recently become of great interest owing to their versatile applications. Besides its general products, mangroves also provide many non timber products such as tannin, fish poison, medicine, food and fodder. Mangrove and mangrove associates contain biological compounds that are active antiviral, antibacterial and antifungal in nature. They also posses antifeedant, molluscicidal and pesticidal properties. Mangrove plants are a rich source of steroids, triterpenes, saponins, flavonoids, alkaloids and tannins. Extracts from different mangrove plants are reported to possess diverse medicinal properties such as antibacterial and antihelminthics. The medicinal value of mangroves and their antimicrobial properties are discussed in this paper in brief.

Mangrove Medicinal Plants: A Review

India has a rich heritage of knowledge on plant based drugs both for use in preventive and curative medicine. A country like India is very much suited for development of drugs from medicinal plants. A large number of these plants grow wild and exploited especially for use in indigenous pharmaceutical houses. Some of these plants produce valuable drugs which have high export potential. The use of plants and plant products as medicines could be traced as far back as the beginning of human civilization. Mangrove plants have been used in folklore medicines and extracts from mangrove species have proven inhibitory activity against human, animal and plant pathogens. The present review deals with the pharmacological activity of mangrove medicinal plants. Several species of mangrove produce bioactive compounds that may control microbial growth. Also, preliminary studies have demonstrated that the mangrove plant extracts have antibacterial activity against pathogenic bacterial strains. Mangrove extracts can also be the possible sources of mosquito larvicides, antifungal, antiviral, anti-cancer and anti-diabetic compounds.

PHARMACOLOGICAL ACTIVITY OF MANGROVE MEDICINAL PLANTS AGAINST PATHOGENIC BACTERIA AND FUNGI

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, Parangipet, Cuddalore District, Tamil Nadu, India. 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.

Antimicrobial activity of mangrove plants of Goa, India against human pathogenic bacteria

2016

Mangroves grow in saline coastal habitats in the tropical and subtropical regions. Mangrove ecosystem is of a great ecological and socioeconomic significance. Mandovi-Zuari estuarine complex in Goa are well known mangrove forests on the west coast of India. Different species of mangrove plants are found and are abundant along the Mandovi estuary of Goa. Mangrove plants are explored from ancient times as folklore medicine against different bacterial and fungal infections. In this study, three different species of mangrove plants, Acanthus illicifolius, Ceriops tagal and Sonneretia caseolaris were collected from three different stations along the Mandovi estuary at Divar, Ribandar and Old Goa. The solvent extracts of dried and powdered leaves of these mangrove plants were further investigated to evaluate the antimicrobial activity against human pathogenic bacteria, Staphylococcus aureus, E.coli, Kliebsiella pneumoniae and Bacillus subtilis using well diffusion method. The results suggest an idea for further characterization of active compound from the effective mangrove plant, which can be used to control the drug resistant pathogenic bacteria.

Evaluation of Antibacterial Activity and Characterization of Phytochemical Compounds from Selected Mangrove Plants

The aim of this study was to investigate the antibacterial activity of n-butanol, petroleum ether, ethyl acetate, ethanol, methanol, and chloroform extracts of the sponges and leaves of different mangrove species (Bruguiera cylindrica, Suaeda maritima, Ceriops decandra, Avicennia officinalis, Rhizophora apiculata, Suaeda monoica, Avicennia marina, and Rhizohora mucronata) against Proteus mirabilis ATCC 7002. Methods and Results: Agar well diffusion method was used to evaluate the antimicrobial activity of selected mangrove extracts. The active compounds from mangrove sponges and leaves with various solvents were examined under Fourier transform infrared (FTIR) spectroscopy. The ethyl acetate extracts, methanol extracts, chloroform extracts, n-butanol extracts, and petroleum ether extracts of selected mangrove leaves (B. cylindrical, S. maritime, A. officinalis, S. monoica, A. marina, R. mucronata) showed good antibacterial activity against P. mirabilis ATCC 7002. FTIR analysis of crude methanol extract of S. monoica showed the presence of amide and alkane groups in phytochemicals. For crude methanol extract of R. mucronata, the presence of phenol, nitro, amide, and alkane groups was revealed. Conclusion: the results obtained revealed industrially important mangrove extracts and the functional groups of plant compounds responsible for great antibacterial activity.

Antibacterial activity of mangrove leaf extracts against human pathogens

Indian Journal of Pharmaceutical Sciences, 2012

Sahoo, et al.: Antibacterial Activity of Mangrove Leaves The antibacterial activity of leaf extract of mangroves, namely, Rhizophora mucronata, Sonneratia alba and Exoecaria agallocha from Chorao island, Goa was investigated against human bacterial pathogens Staphylococcus aureus, Streptococcus sp., Salmonella typhi, Proteus vulgaris and Proteus mirabilis. As compared to aqueous, ethanol extract showed broad-spectrum activity. The multidrug-resistant (MDR) bacteria Salmonella typhi was inhibited by the ethanol extract of S. alba leaf whereas the other two resistant bacteria Staphylococcus aureus and Streptococcus sp. were inhibited by the ethanol extract of leaves of all the species. The aqueous extract of S. alba and E. agallocha showed their activity against P. vulgaris and P. mirabilis, respectively. Phytochemical analysis revealed the presence of saponins, glycosides, tannins, flavonoids, phenol and volatile oils in the leaves of mangroves. Further studies using different solvents for extraction are necessary to confirm that mangroves are a better source for the development of novel antibiotics.
