Polyphenolic compounds of apple may play an important role in physiologic functions related to human health. Different polyphenolics have varied biological activities including antioxidant activity. The objective this study was investigate the profiles polyphenolic different varieties and parts apple. total individual differed significantly among eight cultivars grown Ontario, peels had higher concentrations than flesh. Among tested cultivars, Red Delicious Northern Spy highest Empire...
Different foods possess different bioactive compounds with varied antioxidant capacities. When are consumed together, the total capacity of food mixtures may be modified via synergistic, additive, or antagonistic interactions among these components, which in turn alter their physiological impacts. The main objective this study was to investigate and identify any synergistic combinations. Eleven from three categories, including fruits (raspberry, blackberry, apple), vegetables (broccoli,...
Unextractable phenolics from plant foods and their role in health benefits have become increasingly important. Meal residues of three quinoa seeds free fat extractable were subjected to acid, alkaline, enzymatic hydrolyses. The total individual phenolic compounds released analyzed, 19 phenolics, predominantly acids several flavonoids, identified. concentration bound was highest black followed by red white, regardless the hydrolysis method. Higher contents also showed stronger antioxidant...
The antioxidant activities of eight apple cultivars were studied by using the ferric reducing/antioxidant power (FRAP), β-carotene−linoleic acid model system (β-CLAMS), and photochemiluminescent (PCL) assays. activity apples is highly correlated to total phenolic content (TPC) measured Folin−Ciocalteu method polyphenolic index (TPI) obtained HPLC. Extracts peel flesh analyzed assayed separately. FRAP both extracts correlate well with TPC (r = 0.95 0.99, respectively) TPI 0.82 respectively)....
To assess the potential of essential oils and structurally related synthetic food additives in reducing bacterial pathogens swine intestinal tract.The antimicrobial activity oils/compounds was measured by determining inhibition growth. Among 66 that exhibited > or =80% towards Salmonellatyphimurium DT104 Escherichia coli O157:H7, nine were further studied. Most demonstrated high efficacy against S. typhimurium DT104, E. with K88 pili little lactobacilli bifidobacteria. They also tolerant to...
Acute toxicities of 34 naturally occurring monoterpenoids were evaluated against 3 important arthropod pest species; the larva western com rootworm, Diabrotica virgifera LeConte; adult twospotted spider mite, Tetranychus urticae Koch; and house fly, Musca domestica L. Potential larvicidal or acaricidal activities each monoterpenoid determined by topical application, leaf-dip method, soil bioassay, greenhouse pot tests. Phytotoxicity was also tested on a plant. Citronellic acid thymol Were...
Plants can survive a limiting nitrogen (N) supply by developing set of N limitation adaptive responses.However, the Arabidopsis nla (nitrogen adaptation) mutant fails to produce such responses, and cannot adapt limitation.In this study, was utilized understand further effect NLA on adaptation limitation.Grown with N, could not accumulate anthocyanins instead produced an limitationinduced early senescence phenotype.In contrast, when supplied phosphorus (Pi), mutants accumulated abundant did...
In vitro α-glucosidase inhibition assays and ultrafiltration liquid chromatography with photodiode array detection coupled to electrospray ionization tandem mass spectrometry (ultrafiltration LC-DAD-ESI-MSn) were combined screen inhibitors from hawthorn leaf flavonoids extract (HLFE). As a result, four compounds identified as in the HLFE, their structures confirmed be quercetin-3-O-rha- (1-4)-glc-rha C-glycosylflavones (vitexin-2″-O-glucoside, vitexin-2″-O-rhamnoside vitexin) by...
