BACKGROUND As a by-product of tropical fruit juice industry, passion fruit peel is a valuable functional food. It is rich in antioxidants. To determine its potential antioxidant properties of passion fruit peel, this study aimed to evaluate the effect of extraction conditions on total phenolic content and antioxidant activity. METHODS The extraction conditions were selected from different per...

Certain xanthone derivatives, such as these present in mangosteen fruits, show strong antioxidant activity. On the other hand, evidences accumulated that oxidative stress is involved in epileptogenesis. Therefore, the aim of the present study was to estimate total antioxidant capacity (expressed as a ferric reducing antioxidant power FRAP) and evaluate ability to scavenge free radicals (DPPH me...

Sarcosine is currently one of the most discussed markers of prostate cancer. It is involved in amino acid metabolism and methylation processes that occur during the progression of prostate cancer. In this study, we monitored the effect of the addition of sarcosine (0; 10; 250; 500; 1,000 and 1,500 µM) in a time-dependent manner (0-72 h) on the PC-3 prostate cancer cell line. For the assessment ...

Plants from Gynura family was used in this study, namely, Gynura procumbens and Gynura bicolor. Gynura procumbens is well known for its various medicinal properties such as antihyperglycaemic, antihyperlipidaemic, and antiulcerogenic; meanwhile, G. bicolor remains unexploited. Several nonenzymatic antioxidants methods were utilized to study the antioxidant capacity, which include ferric reducin...

This work was carried out to evaluate the total phenolic content and antioxidant potential (2,2-di-phenyl-1-picrylhydrazyl [DPPH] ferric reducing power [FRAP] methods) of Bauhinia monandra through its organs (leaves, stems roots). The results showed fluctuating contents with a dominance in leaves phytophenols crude hydromethanolic selective AcOEt extracts (57.344 ± 12.35 48.165 4.77 mg E...

Abstract The purpose of this research was to optimize the drying process and maltodextrin concentration black garlic ( Allium sativum L.) aqueous extract powder using response surface methodology. conditions were based on Box-Behnken design, with 17 kinds variations in temperature (50-70 °C), time (18-30 hours), (5-15 %). moisture content, total flavonoid content antioxidant activity (DPPH, ABT...

The total phenolic content and related total antioxidant capacity of 70 medicinal plant infusions was analyzed. Infusions were prepared in common way in which teas are prepared for human consumption. The total phenolics were measured by Folin–Ciocalteau assay. The total antioxidant capacity was estimated by Ferric Reducing/Antioxidant Power (FRAP) assay. To make practical comparison of relative...

objective(s): in food industry, the inhibition of tyrosinase is very important, because this enzyme catalyzes the oxidation of phenolic compounds found in fruits and vegetables into quinones, which contribute in undesirable color and taste of fruits and vegetables. teucrium polium l. var. gnaphalodes (lamiaceae), a wild-growing flowering plant that has many applications in food preparations and...
