Seasonal variation in the antioxidant activity and content of phenolic compounds was studied for the 70% methanol extracts of Sorbus aucuparia leaves harvested monthly over the full course of the growing season. The antioxidant potential of the extracts was evaluated using two complementary in vitro tests: the DPPH (2,2-diphenyl-1-picrylhydrazyl) radical-scavenging assay and the AAPH [2,2'-azob...

Background: Ajuga species are anthelmintic, diuretic, antifungal, and antimycobacterial agents.Lamiaceae members Ajuga postii Briq. and Ajuga relicta P.H.Davis are local endemic species of Turkey. Aim: To give information about the total phenolic contents and antioxidant activities of the species. Methods: The total phenolic contents of the extracts have been quantified with Folin Ciocalteu col...

Baccharis trimera (Less.) DC (gorse) is a plant popularly used for the treatment of obesity. In this study, we prepared three B. trimera extracts aqueous extract (AE), decoction (AE-D), and methanol extract (ME) and investigated their antioxidant effects in six different tests and their anti-adipogenic effect in 3T3-L1 cells. The extracts showed a dose-dependent antioxidant activity in all test...

Jellyfish gelatin was hydrolyzed by different proteases to obtain antioxidative polypeptides. The gelatin hydrolysate obtained by progressive hydrolysis using trypsin and Properase E exhibited the highest hydrolysis degree and antioxidant activity. Three series of gelatin polypeptides (SCP1, SCP2 and SCP3) were obtained by ultrafiltrating the gelatin hydrolysate through molecular mass cut-off m...

The aim of this study was to assess the bioactive compounds of apple and pear peel and pulp in vitro and their influence on plasma lipids and antioxidant potentials in vivo. The antioxidant potentials measured by 1,1-diphenyl-2-picrylhydrazyl (DPPH), beta-carotene bleaching (beta-carotene), and nitric oxide inhibition radical scavenging (NO) tests in apple peel and pulp were significantly highe...

conclusions according to the obtained data, synthesized pyridine based chalcones (3a-3j) could be proposed as potential antioxidant lead compounds. background natural chalcones and also their synthetic derivatives have attracted increasing attention due to various pharmacological applications. development and discovery of new chalcones with antioxidant activities is one of the attracting areas ...

Abstract Rosemary Oil ( Rosmarinus officinalis ) contains carnosic acid, carnosol, and rosmarinic which are sources of active antioxidants. The Secretome MSC has growth factors such as antioxidants that protect HDFs. This study aimed to obtain a gel formulation from secretome combinates with test its effect an antioxidant. antioxidant, propylene glycol humectants, Carbomer 940 gelling agent, tr...

Persistent hepatitis B virus (HBV) infection often leads to the development of chronic hepatitis, cirrhosis and hepatocellular carcinoma. The aim of this study was to estimate the oxidant/antioxidant status and liver function tests in different stages of HBV infection to investigate the role of oxidative stress in the pathogenesis of chronic liver diseases. The study was carried out on 150 cont...

BACKGROUND Use of antioxidants is a means of reducing rancidity of fats and oils in food stuffs. The commercial synthetic antioxidants in food industry have been suspected to cause negative health effects. Therefore as alternatives, there is a strong need in finding new effective and safe antioxidants from natural sources to prevent deterioration of foods, drugs and cosmetics. OBJECTIVES IN O...

The current study was assigned to evaluate the total phenol, total flavonoid content (TPC, TFC) and antioxidant properties of extracts from the aerial parts of Scrophularia frigida (S. frigida). Extracts were also tested by preliminary phytochemical screening as well as cytotoxic activity against Artemia salina, MCF-7 (human breast carcinoma) and SW-480 (colon carcinoma) and L-929 (normal) cell...
