A novel high-frequency, high-power, pilot-plant scale sonochemical reactor was developed and used to study the degradation of dichloromethane, trichloroethylene, phenol, and methyl orange in aqueous solutions. The degradation rates of trichloroethylene, dichloromethane, and phenol were found to exceed those of similar frequency, small-scale bench reactors by factors ranging from 2.5 to 7. The d...

Basella alba fruit with dark blue skin and deep red violet flesh is a potential source of natural colorant. This study was aimed to evaluate the total betacyanin content, total phenol and to analyse the antioxidant activity against DPPH radical, superoxide anions, hydroxyl radical, metal chelating, hydrogen peroxide, FRAP, ABTS and deoxyribose degradation in a dose dependend manner. Betacyanin ...

The popularity of fruit tea is increasing in the world because of its antioxidant properties and attractive taste. The aim of this study was to determine and compare the antioxidant property and phenolic composition of 16 different fruit teas. The antioxidant property and total phenol content of fruit teas depending on the extraction condition (water temperature) were examined using the ABTS (2...

Dried buckwheat herb is used in medicinal products whereas fresh green plant parts, especially sprouts, are consumed as a vegetable. The herb contains fagopyrins, which cause sensitivity to light after ingestion. The aim of this study was to investigate the impact of different growing conditions and the development phase on the content of fagopyrin and phenolic compounds in buckwheat sprouts. T...

A flow injection system using an unmodified gold screen-printed electrode was employed for total phenol determination in black and green teas. In order to avoid passivation of the electrode surface due to the redox reaction, preoxidation of the sample was realized by hexacyanoferrate(III) followed by addition of an EDTA solution. The complex formed in the presence of EDTA minimizes or avoids po...

Roasting is a process that contributes to the formation of compounds and flavors in coffee beans. Temperature length time are main factors roasting process. Generally, range temperatures times varies significantly for different varieties This study aims determine effect on changes chemical characteristics robusta beans (Coffea canephora) from Sidomulyo Village. used brewing methods brew roasted...

Background: Dorema aucheri (Apiaceae) grows in west and southwest of Iran. Young leaves of this plant are used orally as pickle or for cooking some local foods, as well as for the treatment of parasitic digestive infections and constipation. Objective: The aim of present study was evaluation of cytotoxic potential and total phenols determination of D. aucheri young aerial parts extract and fr...
