Analytical methodology optimization to estimate the content of non-flavonoid phenolic compounds in Argentine propolis extracts
(Taylor & Francis, 2014-02-07)
Context: Traditionally, the content of total phenolics (flavonoid phenolics (FP) and nonflavonoid phenolics (NFP)) and flavonoids (flavone/flavonol and flavonone/dihydroflavonol)in propolis has been determined by different ...
Antioxidant Properties and Total Phenolic Content of Eight Salvia Species from Turkey

Relationship Among Phenolic Contents, Seed Predation, and Physical Seed Traits in Mimosa bimucronata Plants
Phenolic contents were compared between Mimosa bimucronata seeds from infested and non-infested fruits to assess induced defense response. By measuring leg length of the bruchid beetle Acanthoscelides schrankiae, we verified ...
Comparative study of phenolic compounds in different Brazilian rice (Oryza sativa L.) genotypes
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2009)
This study was conducted to evaluate the natural variability of total, extractable and non-extractable phenolics in pigmented and non-pigmented rice genotypes (Oryza sativa L.) and to estimate whether the contents and ...
Composition of phenolic acids content in apple (Malus sp) pomace
(UNIV ESTADUAL LONDRINA, 2008)
The present work aimed the study of phenolic acids composition in apple pomace of Gala and Fuji cultivars. Phenolic acids were fractionated in phenolic acids, esterified and insoluble and analyzed by gas chromatography-mass ...
Development of carbon fiber/phenolic resin prepregs modified with nanoclays
(Sage Publications Ltd, 2015-06-15)
This work is focused on the study of the main variables involved in the development of phenolic/carbon prepregs and how these variables are affected by the incorporation of nanoclays. For this, phenolic resin was obtained ...
Determination of Total Phenolic Content in Olive Oil Samples by UV-visible Spectrometry and Multivariate Calibration
The viability of determining the total phenolic content in olive oil samples by chemometric analysis of UV-vis spectral data was studied. As a result, a novel spectrophotometric method that does not require prior analyte ...
Antioxidant activity, ascorbic acid and total phenol of exotic fruits occurring in Brazil
(Taylor & Francis Ltd, 2009-01-01)
The antioxidant activity, ascorbic acid and phenolic content were studied in 10 exotic fruits from Brazil: abiu, acerola, wax jambu, cashew, mamey sapote, carambola or star fruit, Surinam cherry, longan, sapodilla and ...
