The main objective of this study is to present our researches regarding the determination of total polyphenols content of seventeen medicinal plants from Romania using NIR Spectroscopy. For this it were performed correlations between the values obtained f... see more

Grape pomace (GP), resulting from wine making, is rich in antioxidant polyphenols originating from the input material, the grapes. Because of the high production volumes of grape pomace, environmental impact and nutritional content, new ways for its valor... see more

The effect of different processing stages- defatting, solubilization, isoelectric precipitation, neutralisation and lyophilisation on the total phenolic content and protein content of Carica papaya (pawpaw) seeds (CPS) full-fat flour (CFF), defatted flour... see more

The content of total phenolic compounds and flavonoids was measured in methanol beepollens’ and beebreads’ extracts as well as their radical scavenging activity. Beepoleens’ extracts were the most effective DPPH (2,2-diphenyl-1-picrylhydrazyl) radical sca... see more

Polyphenols are the principal grape compounds associated with beneficial health effects.Analytical techniques for the quantification of phenolic compounds of grapes are mostly complicated,time consuming and costly. Method published by Somers and Evans in ... see more

The purpose of this research was to evaluate the total polyphenols content of some fruits (sour cherry and plums) and vegetables (red cabbage and red beetroot), usually consumed in Romania, fresh or processed, using Folin Ciocalteu method. Absorbance was ... see more

Pasta and couscous are popular foods manufactured (in their traditional form) from durum wheat semolina. In recent years, the consumers’ quest for novel, functional, gluten-free, wholegrain foods has prompted the industry to manufacture new pasta and cous... see more

Polyphenols content and antioxidant activity are directly related to the quality of wine. Wine also contains sulfites, which are added during the winemaking process. The present study aimed to evaluate the effects of sulfites on the assays commonly used t... see more

The present study extensively fractionated crude red onion extract in order to identify the polyphenols which contributed most in the total antioxidant capacity of the onion extract using a flash chromatography system. The flash separations produced 70 fr... see more
