The photodegradation of Acid Orange 7 (AO7) was successfully achieved in the presence of Fe(III) ions only under visible light ( λ≥420 nm). Upon adding Fe(III) to AO7 solution, ferric ions formed complexes with AO7 mainly through the azo chromophoric group. This AO7–Fe(III) complex...
Citric acid is a nontoxic tricarboxylic acid naturally present in citrus fruits. Citric acid has a wide range of applications in food, pharmaceutical, and beverage industries. It is used a natural preservative, flavor enhancer, antioxidant, emulsifier, etc. Acid hydrolysis and enzymatic hydrolysis met...
Ellagic acid and ellagotannins have been found in variety of plant sources and the highest concentration reported is in red raspberry. Ellagic acid is usually present in the plant as ellagotannins, which should be converted to ellagic acid by chemical or enzymatic hydrolysis to use as an active...
Source Octanoic acid is widespread in plant oils, free and as glycerides. It is also present in apples, bananas, orange juice and peel, pineapple, cognac, calamus, blue cheeses, cheddar cheese, Swiss cheese, feta cheese, and other cheeses. It is found naturally in various mammals' milk and...
THCA, if present, usually occurred at <0.05 μg/g. Fruit ripening and softening during storage were accompanied with a significant increase of MTCA, in both pears and bananas. Those and previous results confirm that foods are an important source of tetrahydro-β-carbolines in humans. Keywords:...
Its use as an adsorbent material for the elimination of certain pollutants present in water has been showing very interesting results, as it is an abundant material in nature and therefore inexpensive. In this work, Aloe vera was used for the removal of a dye (Orange II). It was decided ...
Folic acid (pteroylmonoglutamic acid) is an orange-yellow crystalline substance that is soluble in water but insoluble in ethanol or less polar organic solvents. It is unstable to light, to acidic or alkaline conditions, to reducing agents, and, except in dry form, to heat. It is reduced ...
Citrus limonoids are a class of chemically related compounds present in lemon, lime, orange and grapefruit. We have shown that nomilin and a limonoid glucoside mixture are potent inhibitors of prolifertation of estrogen receptor-negative... N Guthri,K Morley,S Hasegawa,... 被引量: 63发表:...
It was found that PhSO2CF2Cu/CuI/DMF system could undergo oxidative coupling reaction to give PhSO2CF2I (37) when air was present. A similar oxidative chlorination reaction occurred and PhSO2CF2Cl (38) was obtained when CuCl2 was used instead of CuI (Scheme 9) [17]. Sign ...
