Innovative Combination of Dispersive Solid Phase Extraction Followed by NIR-Detection and Multivariate Data Analysis for Prediction of Total Polyphenolic Content
A novel approach combining the advantages of solid phase purification, near infrared analysis and multivariate data analysis was investigated for the prediction of total polyphenolic content, suitable for a wide range of sample matrices.
Comparison of Common Analytical Methods for the Quantification of Total Polyphenols and Flavanols in Fruit Juices and Ciders
- Medicine, ChemistryJournal of food science
Results obtained can help manufacturers of fruit‐based products choose the most appropriate analytical method for polyphenol quantification as part of a quality assurance program or to convey information on dietarypolyphenol content to consumers.

Characterization of the polyphenol composition of 20 cultivars of cider, processing, and dessert apples (Malus × domestica Borkh.) grown in Virginia.
- Chemistry, MedicineJournal of agricultural and food chemistry
Harrison, Granny Smith, Rome, Winesap, and Black Twig cultivars contained the highest concentration of total flavan-3-ols in flesh, indicating potential to impart desired astringency and bitterness to cider under processing conditions where extraction of polyphenols from peel is minimal.
Antibacterial and antioxidant activities of tannins extracted from agricultural by-products
Tannins extracted from green tea waste could be a natural source for substitutes to present antioxidants as well as antibiotics to combat antibacterial activity and antioxidant activity in agricultural by-products.
PHYTOCHEMICAL ANALYSIS OF LEAF EXTRACT OF AESCULUS INDICA Research Article
Methods for performing qualitative and quantitative analysis of both the aqueous and ethanolic extracts of medicinal plant Aesculus indica suggest that the rich phytochemical content of Aesulus indica may be responsible for its popular and wide traditional use.
