Automated Determination of Total Phenol in Urine
American Industrial Hygiene Association Journal, 1972A fully automated method has been developed to determine total phenol in urine. Results agree well with the accepted manual method. In this automated method, samples are run at the rate of ten per hour. Only 1 to 2 ml of sample is needed. In 1 man-day, forty samples can be analyzed.

Stereoselective Total Synthesis of Phenolic Nonadecanediol
Helvetica Chimica Acta, 2014AbstractA simple and highly efficient synthetic route has been developed for synthesis of 1‐(4‐hydroxyphenyl)nonadecane‐3,5‐diol (1). The two stereogenic centers were generated by employing proline asymmetric α‐hydroxylation (MacMillan α‐hydroxylation), Jacobsen's hydrolytic kinetic resolution (HKR), and, finally, Yamaguchi oxirane opening as key steps

Total Phenolics and Phenolic Acids in Plants and Soils
2007During allelopathic investigations of interrelationships among different plant species in their natural sites, special attention is paid to the presence of phenolic acids (PAs) in dominant plants, plant litter and in the soil. They are localized in all plant organs, both as free and in bound forms i.e.

An improved method for determining total urinary phenol
Journal of Chromatography A, 1978A simple and easily manipulated method is described for th- determination of total urinary phenol. This modification of earlier procedures incorporates the enzymatic hydrolysis of conjugated phenol, extraction of the hydrolysis products into isopropyl ether and final quantitation by gas-liquid chromatography-flame ionization detection.

Relationship between Red Wine Grades and Phenolics. 1. Tannin and Total Phenolics Concentrations
Journal of Agricultural and Food Chemistry, 2010Measuring chemical composition is a common approach to support decisions about allocating foods and beverages to grades related to market value. Red wine is a particularly complex beverage, and multiple compositional attributes are needed to account for its sensory properties, including measurement of key phenolic components such as anthocyanins, total

Phenolic compounds and total phenolic content of commercial wines
2008Over the years, pathological implications have often been remarked in the free radicals formation in the human body, underlining how a diet rich in antioxidant substances can be able to limit oxidative damage. Free radicals are extremely harmful to living organisms to do they attack different constituents of the cell, which leads to acceleration of the

Total antioxidant capacity and phenolics content in fresh apricots
Acta Alimentaria, 2008Food quality analysis addressed to the nutraceutical profile is becoming consistent highlighting the possibility to use the antioxidant capacity as further quality index of many fruit and vegetables species. In this study, the total antioxidant status of several apricot cultivars differing in ripening calendar, pomological traits and geographical ...
