Oxidative stress (OS) is the imbalance between generation of reactive oxygen species (ROS) and body's antioxidant defenses in favor ROS. ROS are chemical that can be neutralized by natural phytochemicals like phenolic compounds present medicinal plants whose extraction depends on solvent system used. Thus, study aimed to evaluate effect two solvents polyphenols content activity Alstonia boonei ...

This study aimed to analyze the extraction time influences on some phenolics and carotenoids determined in chokeberry dehydrated residue. In addition, dynamics of DPPH· radical reduction under influence different amounts extract reaction were registered. For this purpose, fruits belonging ’Melrom’ ’Nero’ cultivars grown experimental plots Research Institute for Fruit Growing Maracineni-Arges ha...

Euphorbia hirta L (Euphorbiaceae) also called asthma herb has long been prescribed in traditional medicine because it exhibits diverse pharmacological actions due to the presence of alkaloids, flavonoids, polyphenols, triterpenoids, and saponins. The present study is aimed at phytochemical antioxidant activity anti-inflammatory screening E. hirta. Extraction dried powder was performed followed ...

The production of pistachio in Tunisia generates a large amount potentially valuable waste, such as leaves, that could be used source bioactive compounds. In this work, the extraction phytochemicals from Pistacia vera L. leaves (male and female) by microwave-assisted (MAE) has been investigated. A response surface methodology (RSM) was for optimization compounds extraction, where independent va...

The aim of this study was to evaluate the content and profile phenolic compounds (PCs) antioxidant properties field-grown leaves, in vitro leaves callus cultures blackberry ‘?a?anska Bestrna’ blueberry ‘Toro’. In shoots selected genotypes were grown either on original Murashige Skoog (MS) medium containing 1 mg/L BA, 0.1 IBA GA3 (‘?a?anska Bestrna’) or MS with macroelements reduced ½, 2 zeatin ...

In this study, six extracts of Arabis carduchorum prepared from solvents varying polarity (water, methanol, ethyl acetate, dichloromethane, and n-hexane) were investigated for their chemical profiles total phenolic flavonoid contents (TPC/TFC) using HPLC–MS/MS spectrophotometric/colorimetric assays, respectively, along with the assessment antioxidant enzyme inhibitory effects. general, polar (m...

This study was intended to investigate the antioxidant activities of different solvent fractions (hexane (HEX), chloroform (CHL), ethylacetate (ETHYL) and methanol (MET) fractions) extract Andrographis paniculata GC-MS profiling most active fraction (MET). The crude fractionated using vacuum liquid chromatography method. Antioxidant activity evaluated total phenolic content (TPC), flavonoid (TF...

BACKGROUND Roots and leaves of the Cermela Hutan (Phyllanthus gomphocarpus Hook. F) plant were studied to determine antioxidant activity, phytochemical compounds, proportion of carbohydrate, crude protein, moisture, ash, fat, total phenolic content (TPC), and total flavonoid content (TFC). MATERIAL/METHODS Ten percent (10%) aqueous extract from both Phyllanthus gomphocarpus roots (PGR) and le...

BACKGROUND Oxidative stress in an intracellular environment created by the accumulation of reactive oxygen species results in oxidative damage to biomolecules which ultimately become a hallmark for severe diseases like cancer, aging, diabetes, and cardiovascular and neurodegenerative diseases. METHODS Various in vitro assays were employed to assess the antioxidant potential of strain, DNA pro...
