“…These results were probably due to the fact that organic molecules, including peptides, are highly susceptible to oxidation by extremely reactive hydroxyl radicals . Alkyl radicals were generated from AAPH in the presence of 4-POBN (Kong et al, 2009). As shown in Fig.…”

This study was conducted to obtain hydrolysates with potent antioxidative activity from rockfish skin gelatin. Gelatin was extracted under high temperature/high pressure using a two-step enzymatic hydrolysis with commercial enzymes such as Alcalase, Flavourzyme, Neutrase, and Protamex. The second rockfish-skin gelatin hydrolysate (SRSGH) was prepared by further incubating the first gelatin hydrolysate (FRSGH), which had been hydrolyzed with Alcalase for 1-h (FRSGH-A1), with Flavourzyme for 2-h (SRSGH-F2). The second gelatin hydrolysate showed higher antioxidative activity of 3.72 as measured by a Metrohm Rancimat and superior angiotensin I-converting enzyme (ACE) inhibiting activity of 0.82 mg/mL. Compared with the gelatin, the relative proportion in SRSGH-F2 was markedly decreased in the 100-kDa peak, whereas it was increased in that less than 100-kDa. The amino acid composition of SRSGH-F2 was rich in glycine (25.9%), proline (10.8%), alanine (9.1%), and glutamic acid (9.1%). In contrast, it was poor in cystine (not detected), methionine (1.6%), tyrosine (0.4%), hydroxylysine (0.9%), and histidine (0.9%). In recent years, demand for natural functional foods has been increasing, and SRSGH-F2 can be used as a functional food ingredient in the food industries. However, further detailed studies on SRSGH-F2 with regard to its antioxidant activity in vivo and the various antioxidant mechanisms are needed.

Fresh fruit and vegetables consumption has increased in the past few years due to the enhanced awareness of consumers for healthy food. However, these products are highly perishable, and losses can be of great significance if postharvest correct management is not provided. Fresh-cut products are of increasing importance, since they are presented to the consumer in a state that allows for direct and immediate consumption. However, those products are even more perishable since cutting can induce a series of senescence associated responses to wounding, and are more susceptible to microbial spoilage. Edible coatings, which intend to reduce ripening processes and protect the fruit from water loss and spoilage may be a good way to enhance the shelf life of these products. More recently, the inclusion of additives into these edible coatings to increase their effectiveness, such as essential oils and their constituents with antimicrobial and antioxidant activities, has been reported and patented.

“…Quercetin was reported to possess antitumor activity and is capable of interacting with carcinogens in gastero intestinal tract; isorhamnetin 3-O-β-D-glucoside has protective effect against oxidation-induced cell damage. [18], isorhamnetin 3-O-β-rutinoside has antioxidant and antiinflammatory activity [19]. Methanol extract has moderate activity against gram-positive (Bacillus subtilis and Staphylococcus aureus) and gram-negative bacteria (Pseudomonas auregenosa, Echerichia coli, Enterobacter sp, Salmonella typhi), so we can show the antibacterial activity of the plant was mainly due to the presence of isolated compounds.…”

KEYWORDSFive main flavonoid glycosides were isolated from the ethanolic extract of Diplotaxis harra (Cruciferae), and were identified as quercetin, isorhamnetin 3-rhamnoside, isorhamnetin 3-o-rutinoside, isorhamnetin 3-glucosyl-4`-rhamnoside and isorhamnetin 3-o-β-glucoside. These compounds were identified according to their Rf values, partial and complete acid hydrolysis, UV, 1 H NMR, 13 C NMR and 2D NMR (HSQC, HMBC) spectroscopy. The alcoholic extract of plant was evaluated against some bacterial strains which showed moderate antibacterial activity, while petroleum ether extract doesn't show any activity.
