Raphanus sativus functional potential: Impact of the analytical extraction technique on the bioaccessibility interpretation

open access: yesFood Safety and Health, Volume 1, Issue 1, Page 93-101, July 2023., 2023
Radishes are an important source of bioactive isothiocyanates. We studied the bioaccessibility of isothiocyanates and I3C of radishes. Analytical implications of human intake were considered. Aqueous‐hydrolysis/DLLME showed good suitability for the bioaccessibility assessment.

Structural and compositional dimensions of phytochemical diversity in the genus Piper reflect distinct ecological modes of action

open access: yesJournal of Ecology, Volume 110, Issue 1, Page 57-67, January 2022., 2022
Crude extract 1H NMR diversity synthesizes the compositional diversity and structural complexity of phytochemical mixtures. Plants can develop chemical diversity through different combinations of structural and compositional biosynthetic mechanisms; thus, methods incorporating both dimensions of phytochemical diversity can provide new theoretical ...

Folin‐Ciocalteu Reaction Alternatives for Higher Polyphenol Quantitation in Colombian Passion Fruits

open access: yesInternational Journal of Food Science, Volume 2021, Issue 1, 2021., 2021
Passiflora edulis Flavicarpa, Passiflora edulis Sims, and Passiflora ligularis Juss are Colombian fruits (passion fruits) of important exportation value. They act efficiently as antioxidants, antifungal, and antimicrobial compounds due to their high polyphenol content. Polyphenols can be quantified by the Folin‐Ciocalteu (F‐C) reaction.

Chemical signature of colorectal cancer: case–control study for profiling the breath print

open access: yesBJS Open, Volume 4, Issue 6, Page 1189-1199, December 2020., 2020
Available screening methods for colorectal cancer have poor reliability and low patient compliance. Cancer cells produce altered metabolites, which are transported in the bloodstream and released in the alveoli; these volatile organic compounds (VOCs) can be detected in exhaled breath.
