Synergistic Moisturizing Activity and Antioxidant Activity between Crude
Polysaccharides and Flavonoids in Discarded Stem of Trollius Chinensis
Bunge
Abstract
This paper aims to investigate the synergistic effects in moisturizing
activity and antioxidant activity between the promising unconventional
polysaccharide and flavonoids from stems of Trollius chinensis Bunge
(TCS). The results showed that the mixture with the mass ratio (w/w) of
7:3 (flavonoids to polysaccharides) appeared better moisture retention
(73.08 ± 2.4%) and scavenging effects on·OH radicals (85.46±0.52 %).
Meanwhile, the mixture with the mass ratio (w/w) of 3:7 (flavonoids to
polysaccharides) unveiled better scavenging effects on DPPH radicals
(44.10±0.81%) and reducing capacity. The results confirmed that the
polysaccharides and flavonoids from TCS have good synergistic effects in
moisturizing activity and antioxidant activity, and have the potential
to be used in the food industry as edible films or edible packaging
materials.
