This work planned to assess the antioxidant prevention agent movement and phenolic content of 41 business restorative creams accessible on homegrown market. The phenol still up in air by Folin-Ciocalteu strategy involving gallic corrosive as a norm. cell reinforcement action was estimated utilizing FRAP (feric limit). 22.5% corrective inspected contained compounds between 2.89 -1.15 2.98-1.91 m...

Tamarind seeds are not consumed despite their high antioxidative activity. In this study, 0-10% tamarind seed powder (TSP) was incorporated into mango juice and cookies. Total phenolics (Folin-Ciocalteu assay), antioxidant activity (2,2-diphenyl-1 picrylhydrazyl (DPPH) radical scavenging assay), flavonoid (aluminum chloride assay), condensed tannins content (Vanillin-HCl assay), and consumer ac...

The antioxidant activity of the phenolic fraction of extra virgin olive oil was assessed in samples that had a decreasing content of antioxidants in the presence and absence of copper ions as a catalyst of autoxidation. The oxidation process was evaluated by measuring primary and secondary oxidation products. Changes in phenols and tocopherols were investigated by high-performance liquid chroma...

In order to supply new information on the antioxidant function of selected beverages for nutritionists and the general public, total phenolic contents of 51 kinds of herbal and tea infusions made in China were measured by the Folin-Ciocalteu method, and their antioxidant capacities were evaluated using ferric reducing antioxidant power (FRAP) and Trolox equivalent antioxidant capacity (TEAC) as...

BACKGROUND Quercetin is one of the most potent antioxidants showing anti-inflammatory, antiproliferative and antitumoral effects; however its short half-life in buffered solution (e.g. body fluids) has so far hampered its introduction into clinical practice. AIM To overcome this inconvenience, quercetin was covalently conjugated into a polymethacrylic acid backbone and the conjugate was teste...

IN THIS STUDY, WE HAVE EXAMINED THE ANTIOXIDANT ACTIVITY AND TOTAL PHENOLIC CONTENT OF DIFFERENT EXTRACTS (INCLUDING WATER, METHANOL, WATER : methanol and acetone) of Nerium oleander L. grown in the north of Iran by employing various in-vitro assay, i.e. DPPH free radical scavenging, reducing power and total antioxidant capacity through the Mo (VI) reduction. The extracts showed different level...

Sargassum has been well acknowledged for the potential natural product of its phlorotannins. Solid-liquid extraction (SLE) is the most common method used to extract them. However, this method has some drawbacks such as low yield and toxic. An alternative ecofriendly method has been proposed, i.e. enzyme-assisted extraction (EAE), proven to be more efficient. The aim is to compare the efficiency...

In the present study, antioxidant potential of the different extract of the whole plant of Aerva tomentosa Forsk. was evaluated by using 2, 2-diphenyl-1-picrylhydrazyl (DPPH) scavenging assay and total phenolic contents was analyzed using the Folin-Ciocalteu reagent method. The methanol extract showed significant activity in antioxidant assay compared to other successive extracts such as peteth...
