Antioxidant properties of sterilized yacon (Smallanthus sonchifolius) tuber flour

Food Chemistry, 2015
The objective of this research work was to investigate the antioxidant properties of sterilized yacon tuber flour. The results revealed for the first time the high antioxidant activity of sterilized yacon flour. The best extract obtained by boiling 8.9% (w/v) of yacon flour in deionised water for 10 min exhibited a total antioxidant capacity of 222±2 ...

Novel octulosonic acid derivatives in the composite Smallanthus sonchifolius

Tetrahedron Letters, 2003
Abstract Two novel octulosonic acid derivatives with a 6,8-dioxabicyclo[3.2.1]octane skeleton that are major water-soluble phenolic compounds were found in the roots of Smallanthus sonchifolius . The structures of these compounds were determined to be (1 R ,2 S ,3 S ,4 R ,5 S ,7 R )-4-hydroxy-7-hydroxymethyl-3-[3-(3,4-dihydroxyphenyl)-1-oxo-2 ...
