this study was conducted to investigate the influences of raw or acetic acid-treated oak acornon the performance and cecal flora of broiler chickens. a total of 340 one-day-old male and female cobb 500 broiler chicks were used in a completely randomized design consisting of five treatments with four replicates and 17 chicks each. first group was fed with a corn-based diet (without oak acorn) as...

Abstract—Feed oil samples which are used as mixed feed raw material were taken from six different feed factories in March, May and July. All factories make production in Konya, Turkey and all of the samples were crude soybean oils. Physical and chemical analyses, free radical scavenger effect, and total phenol content were determined on these oil samples. Moisture (M) content was found between ...

Thirty eight bottles of red wine (Carbanet Sauvignon) were randomly selected based on vintage, region, price, and age (number of months in a barrel). The total phenolic content of each wine was determined using Folin-Ciocalteau assay. The radical scavenging activity was evaluated using 2,2-diphenyl-1-picryhydrazyl (DPPH) assay. Apart from a few bottles that exhibited above average radical scave...

Rice bran, a by-product derived from processing rice, is a rich source of bioactive compounds. Recent studies have suggested that the fermentation can improve their biological activities. This study aimed to determined the level of γ-oryzanol, β-glucan and total phenol contents of fermented rice bran from 21 Korean varieties, as well as to evaluate their antioxidant activities. We also assessed...

Olive oil extraction produces a great volume of residue. These olive mill wastes are known as alpechin. This wastewater is a powerful pollutant, resistant to degradation and presents a severe environmental problem related to its high organic content made up largely of simple phenolic compounds, that have been described as being both antimicrobial and phytotoxic. This paper reviews briefly the a...

The carbon quantum dot (CQD) paper-based analytical device (PAD) has drawn great attention and is being intensively explored. However, the construction of a continuous flow CQD synthesis remains challenging. In this work, reaction apparatus was constructed to synthesize nitrogen-doped CQDs using mixed-solvent system tetraethylene glycol water. optical properties were characterized. found be que...

This study was conducted to investigate the effect of the antioxidant activity of germinated African Yam Bean (AYB) on oxidative stress markers in alloxan induced diabetic rat. Rats were randomized into three groups; control, diabetic and germinated AYB – treated diabetic rats. The Total phenol and flavonoid content and DPPH radical scavenging activity before and after germination were investig...

 Background: The use of natural products as anticancer and antioxidant agents has a long history. Several drugs currently used in chemotherapy were isolated from plant species. Objective: The aim of this study was to evaluate cytotoxicity and antioxidant activity as well as phenol and flavonoid contents of five plant species of Solanaceae family. Methods: Five plant species of Solanace...

Zirconium dispersed in aluminum-pillared montmorillonite was prepared as a catalyst for phenol hydroxylation. The effects of varying the Zr content on the catalyst's physicochemical character and activity were studied with XRD, BET surface area analysis, surface acidity measurements and scanning electron microscopy before investigating the performance for phenol conversion. The zirconia dispers...
