the present study investigates the antioxidant, anticancer, anticholinesterase, anti-genotoxic activities and phenolic contents of flower, fruit and seed methanol extracts of hypericum retusum aucher. the amounts of protocatechuic acid, catechin, caffeic acid and syringic acid in methanol extracts were determined by hplc. total phenolic content of h. retusum seed extract was found more than fru...

Appearance of a lag period dependent on pH in the expression of the catecholase activity of a polyphenoloxidase extracted in a latent state from Airen grape (Vitis vinifera L.) berries, is revealed, suggesting the hysteretic nature of the enzyme. The lag time was independent of enzyme concentration, indicating that slow pH-induced conformational changes in the protein must occur during assay. R...

Tamarind seed, a household waste from the kitchen is used for the sorptive removal of fluoride from synthetic aqueous solution as well as from field water samples. Batch sorptive defluoridation was conducted under variable experimental conditions such as pH, agitation time, initial fluoride concentration, particle size and sorbent dose. Maximum defluoridation was achieved at pH 7.0. Defluoridat...

• Bentonite fining is widely used to increase the protein stability of a wine. Some authors have proposed treatment of the juice itself, rather than the wine, to enhance fermentation performance and flavor, and increase stability. Some authors have reported that this practice yields stable wines not requiring further fining, whereas others have found no increase in stability when treating the j...

Antibiotic resistance makes Antimierobial peptides (AMPs) agents an alternative for treatment of pathogenic diseases. They are isolated from various invertebrate animals, vertebrates and plants. The present study shows the electrophoretic pattern of protein and peptides from Vicia faba seed and reports our first attempt to study the antibacterial activity of Vicia faba seed extract. The crude e...

We determined whether immersion in 49 degrees C water for 20 min, a quarantine treatment developed for disinfestation of fruit flies in lychee, Litchi chinensis Sonn., and longan, Dimocarpus longan (Lourd.) Steud., exported from Hawaii, would also disinfest fruit of two species of Cryptophlebia. The pattern of tolerance to heat in Cryptophlebia illepida (Butler) was generally eggs < neonates < ...

Three polysaccharide-protein complexes of longan pulp (LP1-3) were isolated in this work. Their physicochemical characteristics and immunomodulatory effects on splenocytes, natural killer (NK) cells and macrophages in vitro were investigated. The carbohydrate portions of LP1-3 were principally composed of glucose, arabinose and mannose. LP3 displayed the maximal moisture absorption, and the the...

This study was carried out to determine the effects of supplementing different levels (0, 0.5 and 1% of buffered rumen fluid) of methanolic extract of pomegranate peel, on rumen fermentation kinetics of four oil seed meals (soybean meal, cotton seed meal, rapeseed meal and sunflower seed meal), using in vitro gas production technique. The samples were incubated in syringes containing rumen liqu...

PURPOSE In the present study cytotoxic effects of the alcoholic extract of Dorema Glabrum seed on viability of WEHI-164 cells, mouse Fibrosarcoma cell line and L929 normal cells were compared with the cytotoxic effects of Taxol (anticancer and apoptosis inducer drug). METHODS To find out the plant extract cytotoxic effects, MTT test and DNA fragmentation assay, the biochemical hallmark of apo...
