Major Phenolics in Apple and Their Contribution to the Total Antioxidant Capacity

Journal of Agricultural and Food Chemistry, 2003
The contribution of each phytochemical to the total antioxidant capacity of apples was determined. Major phenolic phytochemicals of six apple cultivars were identified and quantified, and their contributions to total antioxidant activity of apples were determined using a 2,2'-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) radical scavenging assay and

The Extraction of Total RNA by the Detergent and Phenol Method

2003
Successful extraction of RNA depends on the quantitative recovery of pure nucleic acids in an undegraded form. In practice, this means that a selective extraction process is required to remove all the unwanted cellular material in a manner that minimizes degradation of the RNA by hydrolysis or ribonuclease activity.

Determination of total phenolic compounds in compost by infrared spectroscopy

Talanta, 2016
Middle and near infrared (MIR and NIR) were applied to determine the total phenolic compounds (TPC) content in compost samples based on models built by using partial least squares (PLS) regression. The multiplicative scatter correction, standard normal variate and first derivative were employed as spectra pretreatment, and the number of latent variable

Total Synthesis of Honokiol via Oxidative Phenol Coupling

Organic Letters
Abstract Herein we disclose the total synthesis of honokiol in six steps in an overall yield of 66%. Two distinct routes were explored, with the key steps being highly efficient and selective cross-couplings of commercially available phenols to construct the main biphenolic backbone.

Assessing wines based on total phenols, phenolic acids and chemometrics by multivariate analyses

2013
The aim of this study was to investigate the phenolic profile of some red wines produced from native Turkish grape varieties (Vitis vinifera Öküzgözü, V. vinifera Boğazkere and V. vinifera Shiraz) and some red fruit wines produced from pomegranate (Punica granatum L.), myrtle (Myrtus communis L.) and black mulberry (Morus nigra L.). Red grape wines and
