BACKGROUND Seaweeds are taxonomically diverse benthic algae, which are rich in bioactive compounds. These compounds have a potential application in medicine. OBJECTIVES The aim of the study was to investigate the bioactive properties of three seaweed samples, Enteromorpha antenna, Enteromorpha linza and Gracilaria corticata were collected from the shoreline of Mahabalipuram, Tamilnadu. MATE...
New thiazolidine-4-one derivatives of 2-(4-isobutylphenyl)propionic acid (ibuprofen) have been synthesized as potential anti-inflammatory drugs. The structure of the new compounds was proved using spectral methods (FR-IR, 1H-NMR, 13C-NMR, MS). The in vitro antioxidant potential of the synthesized compounds was evaluated according to the total antioxidant activity, the DPPH and ABTS radical scav...
BACKGROUND Traditionally, Pine has been used to treat oxidative and inflammatory disorders. The study was aimed to investigate biological potential of phytoconstituents of Pinus plant species: Pinus roxburghii, Pinus wallichiana and Pinus gerardiana using in-vitro antioxidant, anti-inflammatory and antimicrobial methods. METHOD The hydro-alcoholic extraction of dried plant: stem bark was done...
UNLABELLED Moringa oleifera is used in Thai traditional medicine as cardiotonic. Recent studies demonstrated its hypocholesterolaemic effect. However, to be clinically useful, more scientific data are needed. AIM OF THE STUDY We investigated the antioxidant, hypolipidaemic and antiatherosclerotic activities of Moringa oleifera leaf extract. MATERIALS AND METHODS Scavenging activity of the e...
The slightly water-soluble flavonoid quercetin (QUE) and its inclusion with either beta-cyclodextrin (betaCD), hydroxypropyl-beta-cyclodextrin (HP-betaCD) or sulfobutyl ether-beta-cyclodextrin (SBE-betaCD) were investigated. The stoichiometric ratios and stability constants describing the extent of formation of the complexes have been determined by phase-solubility measurements; in all cases ty...
The antioxidant properties oí Acantholippia deserticola, a herb used in traditional northern Chilean medicine was studied using free radical-generating systems. The 50% aqueous-ethanol extract oí Acantholippia deserticola protected against non-enzymatic lipid peroxidation in microsomal membranes of rat, induced by an Fe++-ascorbate system and measured spectrophotometrically by the TBARS test, a...
The antioxidant potential of the ethanol extract of Vitex negundo L. was evaluated by using 1, 1diphenyl-2-picrylhydrazyl (DPPH), hydrogen peroxide, total antioxidant capacity and erythrocyte (RBC) membrane stabilization assays. The extract showed significant activities in all antioxidant assays compared to the reference antioxidant ascorbic acid in a dose dependent manner. In DPPH and hydrogen...
Eleven Lactobacillus plantarum strains isolated from traditional Chinese fermented foods were investigated for their in vitro scavenging activity against hydroxyl and 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radicals, and their resistance to hydrogen peroxide. L. plantarum C88 at a dose of 10(10) CFU/ml showed the highest hydroxyl radical and DPPH scavenging activities, with inhibition rates o...
To quantify the major secondary metabolites and the antioxidant potential of methanolic extract of Indigofera trita. The methanolic whole plant extract of Indigofera trita (MIT) was analaysed by HPLC and GC to determine various Phytochemicals. Free radicals scavenging activity of extract by using DPPH, NO and Super oxide radicals generated in vitro. The Methanolic extract of I. trita was found ...
BACKGROUND Adzuki sprouts are one of more valuable but still underappreciated dietary supplements which may be considered as functional food. Sprouting reduces anti-nutritional factors and increases the bioavailability of macro and micronutrients and also affects phytochemical levels. Exposure of plants to abiotic stresses results in change in production of phytochemical compounds. The aim of t...
