Phytochemistry by design: a case study of the chemical composition of Ocotea guianensis optimized extracts focused on untargeted metabolomics analysis

Abstract

Several extraction parameters were evaluated in order to establish their influence on the chemosystematic research of angiosperms.

Improvement of antioxidant properties of jujube puree by biotransformation of polyphenols via Streptococcus thermophilus fermentation

“…According to previous studies, a widely untargeted metabolomics method was implemented to fully understand changes in the composition or content of phytochemicals ( Antonio et al, 2020 ). With reference to the Metware database, the results showed that a total of 575 secondary metabolites were identified, namely, 140 phenolic acids, 178 flavonoids, 12 quinones, 37 lignans and coumarins, 12 tannins, 64 alkaloids, 109 terpenes, one steroid, and 22 other metabolites.…”

Ocotea(Lauraceae) Amazonian essential oils chemical composition and their tyrosinase inhibition to use in cosmetics

“…Lauraceae are internationally known for having Boletín Latinoamericano y del Caribe de Plantas Medicinales y Aromáticas/ 522 aromatic species and Ocotea is one of the most complex genera of this family (Antonio et al, 2020). After centuries of uncontrolled exploration in the Amazon region leading to the identification and exploitation of many species, essential oil-producing species continue to have economic interest, though few chemical and pharmacological studies have been published in the literature despite the number of species of interest.…”

O “Des-Envolvimento” Insustentável e Agricultura Molecular na produção de bioativos

“…Assim, e diferentemente dos métodos clássicos de prospecção, para alcançar objetivamente um bioproduto fitoquímico é essencial o planejamento para as características desejadas ao produto final desde os processos iniciais de coleta, limpeza, secagem e extração. A este processo fitoquímico orientado para o produto designamos Phytochemistry by Design, derivado do Quality by Design, que possui os mesmos princípios, mais amplos [4] .
