SYNTHESIS OF NATURAL-DERIVED POLYPHENOLS AS POTENTIAL ANTICANCER AGENTS
… alkaloids, non ribosomial peptides and polyphenols, these latter directly derived from shikimate pathway, as phenylpropanoids and lignans, or from a mixed biosynthetic pathway (shikimate/ acetate and/or malonate pathways), as stilbenoids or flavonoids. My thesis is devoted to the family …

Antioxidant properties and anti-cancer effects of polyphenols in sweetpotato leaves
… showed that the 2019 SPL possessed higher total polyphenols and antioxidant capacity compared to the 2018 SPL. Among 2019 SPL varieties, SPL1, SPL3, SPL9, SPL11, and SPL28 were selected to evaluate further anti-colon effects. In these 5 SPL varieties with the highest antioxidant and polyphenol …

Characterization of polyphenols in leaves of four desiccation tolerant plant families
Polyphenols in plants are known to act as antioxidants, antimicrobials, antifungal, photoreceptors, visual attractors and as light screens. In this study polyphenols in angiosperms found in southern Africa and called resurrection (desiccation tolerant) plants were studied. These plants are …
