This study investigated the phytochemical, antimicrobial and antioxidant properties of methanolic leaf fractionated extracts of Excoecaria agallocha. Antibacterial activity test of fractionated extract of Excoecaria agallocha was conducted via Disk diffusion assay. Micro titer broth dilution technique was performed to determine the minimum inhibitory concentration (MIC) and Minimum Bactericidal Concentration (MBC). Qualitative and quantitative DPPH radical scavenging activity determines the antioxidant activity in E. agallocha. Chromatographic separation was completed using thin layer chromatography (TLC) and column chromatographic techniques. Phytochemical screening of fractionated extract revealed active constituents including alkaloids, saponins, flavonoids, terpenoid and tannins. In vitro antibacterial activity of columnfractionated extract demonstrated inhibitory effect against Flavobacterium indicum, Chryseobacterium meningosepticum, Chryseobacterium indologenes and Chryseobacterium gleum isolated from diseased fish. MIC and MBC of E. agallocha fractionated extract was 1.56 mg/ml and 3.12 mg/ml, respectively. TLC-based qualitative DPPH analysis revealed antioxidant activity in E. agallocha extract, specified by yellowish stain on maroon color TLC plate. These bands indicate the presence of various compounds that could act as potential antimicrobial agents. The present study indicates that E. agallocha leaves contain active phytochemicals which inhibit bacteria and could be useful in the treatment of microbial infections in fish.

“…betulinic acid, taraxerol and taraxerone) have been isolated from A. marina bark (Zhu et al, 2009). Due to their aromatic properties, these compounds are used as flavors, perfumes, soaps, but also as antimicrobial and antifungal agents (Bandaranayake, 2002;Chandrasekaran et al, 2009). Betulinic acid has been discovered to possess strong antitumor and anticancer properties against human melanoma and breast cancer cells (Mertens-Talcott et al, 2012;Pisha et al, 1995), while taraxerol is an antiinflammatory agent (Yao et al, 2013).…”

Halophyte species of United Arab Emirates are a source of unique active phytochemicals, potentially due to the extreme environmental conditions under which the plants grow in the UAE. These phytochemicals make the native halophytes possibly interesting crops for biorefining, where biofuel production is combined with the production of value added chemicals, improving the economic feasibility of both process. Phytochemicals found in these species are widely recognized and researched as potential pharmaceutical and nutraceutical products. We reviewed the literature for secondary metabolites from species from the following halophyte families: Aizoaceae, Amaranthaceae (incl. Chenopodiaceae), Avicenniaceae, Zygophyllaceae. The review revealed that plant species belonging to these families contain valuable phytochemicals, such as fatty acids, terpenoids, flavonoids, alkaloids, steroids, tannins, saponins, quinones and coumarins, many of which have been reported to have therapeutic effects in humans.

This review examines the chemical compositions and bioactivities of mangrove plants belonging to the Rhizophoraceae family. The Rhizophoraceae family of true mangrove plants is the most common and is also widely distributed species. It consists of 24 species across four genera. Of the 24 species, 12 species remain unexamined for their phytochemical constituents. There have been 268 metabolites reported from 16 species. The key phytochemical constituents identified across the family are the diterpenoids and triterpenoids. The major diterpenoids include pimaranes, beyeranes, kaurenes, dolabranes and labdanes whereas the significant triterpenoids are lupanes, dammaranes and oleananes. Disulphides, dolabranes and labdanes are considered to be the chemotaxonomic markers of the genera Bruguiera, Ceriops and Rhizophora respectively.
