The conditions for microwave-assisted extraction (MAE) of total flavonoids (TF) and total phenols (TP), and antioxidant activity from celery (Apium graveolens L.) leaves by response surface methodolog...
In order to provide a general picture of phytochemical characteristics of nectar honey, honeydew, and mixed honeys, an overall comparison of physicochemical parameters, and phenolic profile as well as...
Total phenolics and flavonoids contents in Chinese wild rice were predicted using Near Infrared (NIR) spectroscopy as a rapid method. A Partial Least Square (PLS) algorithm was applied to perform the ...
Using electron paramagnetic resonance (EPR) spectroscopy, antioxidant properties of chestnut extracts have been investigated as a source of phenolic compounds. In addition to their high antioxidant ac...
Analyses of Free and Bound Phenolics in Rice     rice  phenolic  ferulic acid  diferulic acid       font style='font-size:12px;'> 2009/7/7
Free and bound phenolics in 21 japonica cultivars (Oryza sativa) of rice bran and polished rice were analyzed using 3D-HPLC. Although we observed high content variations among cultivars, the major fre...
Secondary plant metabolites are important native food components, which are becoming more and more interesting due to their physiological effects on human beings. One of the largest groups of these co...
Selenium, vitamin C, pungency, amino acids, phenolics content and antioxidant activities of two Egyptian onion varieties, namely white (Giza-6) and red (Beheri) onions have been studied. Data analysis...
The antioxidant activities and total phenolic content of 30 samples of acacia honey from Croatian territory were analysed. Phenolics were determined by the modified Folin-Ciocalteu method, antiradical...
The objective of this research was to evaluate the effect of blackcurrant mash blended with apple pulp during juice production and storage on its phenolic composition, antioxidant activity, L-ascorbic...
Rolled oats, a processed oat product, contain about 4 g of (1→3),(1→4)-β-glucan (β-glucan) per 100 g. It also contains 27.0 mg of ferulic acid and 3.5 mg of p-coumaric acid. Moreover, the presence of ...
Bond dissociation enthalpies (BDEs) for phenolic constituents from Tessaria integrifolia RUIZ. et Pavon and Piper elongatum VAHL. have been calculated using the semi-empirical molecular orbital (MO) m...
Extractions were performed using non-toxic media composed of water/ethanol mixtures and hydrochloric, acetic or tartaric acid. Recovery efficiency was assessed by monitoring the antiradical activity (...
