Antioxidant activity of protocatechuates evaluated by DPPH
01 03 2016This could also contribute to explain the higher antioxidant value of caffeates than that of protocatechuates The antioxidant activity of amphiphilic molecules implicates the mobility and partition between different phases in an emulsion Thus alkyl protocatechuates would partitionate between the aqueous phase the interface and the oil phase according to their saturated alkyl chain
Multifunctional Antioxidant Activities of Alkyl Gallates
A series (C 1 to C 16) of alkyl gallates was tested for their antioxidant activity for food protection and human health One molecule of alkyl gallate regardless of alkyl chain length scavenges six molecules of 1 1-diphenyl-2-picrylhydrazyl (DPPH) Alkyl gallates inhibited the linoleic acid peroxidation catalyzed by soybean lipoxygenase-1 (EC 1 13 11 12 Type 1) without being oxidized The

Fruits can be easily infected and damaged by microbes Cold storage is a popular approach used to extend the shelf-life of fruits In this paper the effect of caffeic acid on physiological parameters and shelf-life of mulberries (Morus alba L ) stored for 21 days at 4C was evaluated The results showed that the shelf-life was significantly improved in the mulberries treated with the
1 Introduction
The gastroprotective activity in acidified ethanol is partly attributed to the antioxidant mechanisms while anti-secretory anti-inflammatory and regeneration of the gastric mucosa are evoked as part of its antiulcer mechanism of action The gastric ulcer healing of HEPu involves restoration of the altered cytokines levels to near normal It has no in vitro anti-H pylori activity These
Antioxidant Activity of Alkyl Gallates and Glycosyl Alkyl
22 antioxidant activity of alkyl gallates when increasing alkyl chain length was observed for emulsions 23 prepared with lecithin Medium-size alkyl gallates (C6-C12) were the best antioxidants In contrast for 24 emulsions prepared with Tween-20 the antioxidants seem to follow the polar paradox Glucosyl alkyl 25 gallates were shown previously to be better surfactants than alkyl gallates

AbstractExperiments were performed to assess the dose-dependent effects of quercetin kaempferol (+) catechin and (−) epicatechin on superoxide radical production through the modulation of manganese superoxide dismutase and xanthine oxidase activities The experiments were carried out at flavanoid concentrations ranging from 1 M to 100 M
Isopropyl Caffeate: A Caffeic Acid Derivative—Antioxidant
Phenolic compounds among them isopropyl caffeate possess antioxidant potential but not without toxicity and/or adverse effects The present study aimed to evaluate the antioxidant activity and toxicity of isopropyl caffeate through in silico in vitro and in vivo testing The results showed that isopropyl caffeate presents no significant theoretical risk of toxicity with likely moderate

How to increase your antioxidants levels
A measure called the oxygen radical absorbance capacity (ORAC) is commonly used to measure the antioxidant capacity of different foods The higher the ORAC value the greater the antioxidant activity of the food The recommended amount of antioxidants required to maintain a healthy body is an intake of between 3000 and 5000 ORAC units per day
