Automated Determination of Total Phenol in Urine

American Industrial Hygiene Association Journal, 1972
A 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.

Total synthesis of phenolic alkaloids

Tetrahedron Letters, 1983
Abstract The total synthesis of (±)-ribaline is reported; in combination with earlier findings, this represents a formal total synthesis of (+-)-ribalinidine.

Total Phenolics and Phenolic Acids in Plants and Soils

2007
During 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.

Antioxidant Activity, Total Phenol, and Total Flavonoid of Syzygium Polyanthum

2021 IEEE International Conference on Health, Instrumentation & Measurement, and Natural Sciences (InHeNce), 2021
Free radicals are molecules that have an unpaired electron in their outer orbital so they are highly reactive. Antioxidants (free radical scavenging compounds) are substances that can neutralize free radicals, or materials that function to prevent the body's biological systems from being oxidized excessively.

On the spectrophotometric determination of total phenolic and flavonoid contents

Acta Biologica Hungarica, 2013
Spectrophotometric assays assessing total phenol and flavonoid content in plant samples are cheaper and faster and thus more accessible methods than analytical chromatography techniques, although these identify compound categories rather than individual compounds.

An improved method for determining total urinary phenol

Journal of Chromatography A, 1978
A 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.

Stereoselective Total Synthesis of Phenolic Nonadecanediol

Helvetica Chimica Acta, 2014
AbstractA 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

Relationship between Red Wine Grades and Phenolics. 1. Tannin and Total Phenolics Concentrations

Journal of Agricultural and Food Chemistry, 2010
Measuring 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

2008
Over 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 phenols in enriched biscuits

2006
Biscuits are cereal based food widely consumed by all populations and therefore appropriate to be “ carrier” for different health protecting compounds. Due to well documented beneficial effects of high intake of fibres, confectionery industry offers new types of biscuits enriched with fibres of different origin.
