Experiments were performed in order to check whether biological activity of some organophosphorous compounds widely applied as herbicides: 2,4-dichlorophenoxyacetic acid (1) and its sodium salt (2), N-phosphonomethylglycine acid (3) and its sodium salt (4), diethyl 1-butylamino-1-cyclohexanephosphonate (5) and diethyl 9-butylamino-9-fluorenephosphonate (6) followed from their oxidative activity...

The antioxidative substances contained in cacao liquor, which is one of the major ingredients of chocolate, were separated by column chromatography and high-performance liquid chromatography. Three major compounds were purified and two of them were identified by 1H, 13C NMR and mass spectra as (-)-epicatechin (EC) and (+)-catechin (CA). Their antioxidative activity was measured by monitoring th...

The radical scavenging effect and protective potential from oxidative damage by radical generator, 2,2'-azobis (2-amidinopropane) dihydrochloride (AAPH), in renal epithelial LLC-PK1 cell of broccoli (Brassica oleracea) were investigated and identified the active components under the bioassay-linked fractionation method. The MeOH extract, and fractions of CH2Cl2, BuOH and H2O from broccoli showe...

OBJECTIVES Eriobotrya japonica belongs to the Rosaceae. Studies have shown that the flowers of this plant are rich in phenolic and flavonoid compounds. Accorrdingly, the evaluation of antioxidative effects of Eriobotrya japonica Flower Extract (EJFE) have been performed in vitro. MATERIAL AND METHODS In this study, to investigate the influences of components of EJFE on its antioxidative activ...

Propolis is a natural product made by honeybees and contains various compounds, including flavonoids, amino acids and fatty acids. These compounds are considered to have antiviral, antibacterial and antioxidative properties. On the other hand, cadmium (Cd), an industrial and environmental pollutant, preferentially accumulates in the kidney and induces kidney injury. We previously reported that ...

tients, and its blockade is believed to enable cancer patients to live longer. Thus, it is important to find promising antimetastatic agents. A variety of compounds have been shown to be benefitial for the inhibition of cancer metastasis. Some of them involve mechanisms based on the invasive inhibition of tumor cells by interfering with tumor adhesion to extracellular matrix components, inhibit...

Purpose: To determine the potent antioxidants among six hydroxy-bearing cinnamaldehyde compounds and their corresponding acids. Methods: The antioxidative activities were evaluated by scavenging 2, 2’-diphenyl-1-picrylhydrazyl (DPPH) free radicals and anti-hemolysis of human red blood cells (RBCs). Fourier transform infrared spectrometry(FT-IR, nuclear magnetic resonance (NMR)and mass spectrome...

Introduction: Free radicals cause several human diseases. Antioxidants decrease the risk of cardiovascular diseases and heart attack, and prevent the development of cancers through neutralization of free radicals. This study set out to determine the antioxidative properties of Citrullus colocynthis growing in Khuzestan. This plant is traditionally used for the treatment of type II diabetes. ...
