Viola tricolor L.

Violaxanthin is a naturally derived diepoxy xanthophyll carotenoid and light-harvesting accessory pigment with biological activities such as antioxidation and anti-inflammation. Violaxanthin transfers excitation energy to chlorophyll a under low-light conditions. Violaxanthin participates in the xanthophyll cycle and dissipates excess light energy in the form of heat, thereby protecting thylakoid membrane lipids from photo-oxidative damage. Violaxanthin exhibits activities including inhibition of lipid peroxidation, quenching of singlet oxygen, scavenging of DPPH free radicals, and scavenging of ABTS⁺ free radicals. Violaxanthin can be used in antioxidant-related research.

Viola tricolor polysaccharide is a polysaccharide derived from Viola tricolor.
