Abstract:
Objective: To identify the antiviral antioxidant and toxicological evaluation of marine halophyte.Methods:Mangrove associates such as Salicornia brachiata, Clerodendron inerme, Rhizophora lamarckii, Suaeda maritima were collected. In vitro antiviral studies such as HBsAg binding assay, DNA polymerase inhibition assay, RT inhibition assay were carried out. Moreover, antioxidant properties, ash content, elemental analysis, LD50 analysis were measured for theS. maritima leaf extract which was the most potent. Results: S. maritima leaf extract showed minimum concentration of IC50 value with HBsAg binding assay, DNA polymerase inhibition assay, RT inhibition assay as 325.98, 843.09 and 587.32 μg/ml concentrations respectively. Antioxidant properties of S. maritima leaf extract showed the minimum concentration (23.64±5.27μg/ml) of IC50 value with the nitric oxide scavenging assay, followed by DPPH assay (112.03±18.39μg/ml). The ash content of S. maritima leaf extract was varied between 8.05% to 87.30%concentrations. The elemental analysis of S. maritima showed the values within the limits of WHO guidelines. The lethal dose of S. maritima leaf extract was identified as 3000 mg/kg/body weight. The sub acute toxicity was not showed any significant differences with organ weights between control and extract treated animals. Biochemical parameters such as SGOT, SGPT, ALP, sugar and urea were not showed any significant variations between control and extract treated animals. But, the results of haematological parameters such as WBC (6600±234.90 cells/cumm), lymphocytes (69±14.09), polymorphs (38±9.38), eosinophils (02±0.00) were found significantly increased with extract treated animals. Phytochemical analysis of S. maritima leaf extract showed the presence of various phytochemical constituents such as reducing sugars, polyophenols, flavonoids and tannins with the leaf extract. Conclusions: The results of the present findings pave the way for the identification of novel molecules for the possible utilization of antiviral and antioxidant drugs from Suaeda maritima leaf.
