Ascorbic acid, phenolic compounds and carotenoids were extracted from acerola (Malpighia emarginata DC.) by-products using gas-expanded liquids (GXLs) based on carbon dioxide expanded ethanol at 40 °C 7 MPa. The generated in the processing of acerola: bagasse (seed peel) non-pomace (from juice clarification step), studied separately. overall extraction yields obtained 3.8 12.9 g/100 g for non-p...

drought is the most common environmental stress in vineyard occurs in soils with low water content, even in irrigation condition. to evaluate foliar spraying of ascorbic acid under drought stress, a research during 2012 to 2013 years in the natural environment, and one year after the establishment of the cuttings in clay loam soil was conducted. cultivars with two-level white seedless and khosh...

INTRODUCTION To control the tissue browning phenomenon, callus growth, total phenolics and paclitaxel production, in the current investigation, we evaluated the effects of citric acid and ascorbic acid (as antioxidants) and glucose, fructose and sucrose in callus cultures of Taxus brevifolia. METHODS To obtain healthy callus/cell lines of Taxus brevifolia, the effects of two antioxidants asco...

The aim of this study was to prepare the freeze dried powder noni (Morinda citrifolia) pulp and determine contents bioactive antioxidant capacity. Seed, peel, lyophilized were characterized in terms physico-chemical, carotenoids, chlorophyll, sugars, ascorbic acid, phenolics, flavonoids antioxidants contents. Phenolic compounds determined by LC-MS. showed high levels phenolics (7486.38 µg GAE/g...

Reproductively active oysters were fed daily with 0.2 g algal paste containing 0, 0.1, and 1.0 microgram polychlorinated biphenyls (PCBs) (1:1:1 mixture of Aroclor 1242, 1254 and 1260) for either 15 or 30 days, and accumulation of PCBs in different organ tissues and eggs assessed. The effects of PCB exposure on lipid content, lipid class and fatty acid composition were also evaluated. PCBs were...

background & aim: free radicals play a crucial role in the development of tissue damage in various human diseases such as cancer, aging, neurodegenerative disease, malaria and arteriosclerosis, and pathological events in living organisms. antioxidants may have an important role in the prevention of these diseases. the aim of this study is to evaluate potency of scavenging of dpph free radic...

Dried carpophores of Ganoderma lucidum were exposed to the hot water extraction and alcohol precipitation to obtain polysaccharides, which were than refined by the dialyses. Dry polysaccharide extract (GL-I) was partially purified and used for the investigation of antioxidant properties. The antioxidant activity was determined by the conjugated diene method, ascorbic acid and α-tocopherol were ...
