Polyphenolic Composition and Antioxidant Activity (ORAC, EPR and Cellular) of Different Extracts of Vitroplants and Natural Roots.

Plant biochemistry studies have increased in recent years due to their potential to improve human health. is an extremophile plant with an interesting polyphenolic profile. However, its biomass is scarce and occasionally available.

Polyphenolic distribution in organs of , an extremophile plant from Chilean Atacama desert.

The polyphenolic distribution on different organs of , an extremophile plant from the Atacama "Flowering Desert", is presented herein for the first time. For this purpose, the total phenolic content and antioxidant capacity of ethanolic extracts from leaves, tuberous root and flowers of different colors were evaluated. Orange and red flowers showed the highest polyphenolic and flavonoid content.
