objective: there has been a growing interest in finding plants with biological active ingredients for medicinal application. materials and methods: three colors of petals of althaea officinalis (a. officinalis) flowers, i.e., pink, reddish pink, and white were examined for total antioxidant activity and flavonoids content. results: the reddish pink flowers of a. officinalis have more antioxidant...
با توجه به نقش مهم مواد آنتی اکسیدانی در پیشگیری از برخی عوامل بیماریها و نیز با توجه به اثرات آتتی اکسیدانی گونه های مختلف euphorbia از جمله e.hirtaو ازآنجاکه تاکنون هیچگونه مطالعه ای برروی اثرآنتی اکسیدانی گیاه e.splendida انجام نگردیده است(3 و 4).برآن شدیم تااثرآنتی اکسیدانی عصاره تام متانولی و فراکسیون های حاصل ازبخش هوایی گیاه رابرای اولین باربا سه روش مختلف زیر بررسی کرده ونتایج حاصله رام...
Two phenolic compound parameters (total phenolic and flavonoid contents) and 5 antioxidant parameters (DPPH [2, 2-diphenyl-1-picrylhydrazyl] radical scavenging activity, HRSC (hydroxyl radical scavenging capacity), FRAP (ferric ion reducing antioxidant power), CUPRAC (cupric ion reducing antioxidant capacity), and MCA (metal chelating activity) were measured in bulbs and bolts of 43 garlic cult...
Bacterial extracellular proteases from six strains of marine bacteria and seven strains of terrestrial bacteria were prepared through fermentation. Proteases were analyzed through substrate immersing zymography and used to hydrolyze the collagen and muscle proteins from a salmon skin byproduct, respectively. Collagen could be degraded much more easily than muscle protein, but it commonly showed...
Antioxidant capacities of ethylacetate, butanol, and water fractions of peel, pulp, and seeds of Canarium odontophyllum Miq. (CO) were determined using various in vitro antioxidant models. Ethylacetate fraction of peel (EAFPE) exhibited the highest total phenolic (TPC), total flavonoid content (TFC), and antioxidant activities compared to pulp, seeds, and other solvent fractions. Antioxidant ca...
