Violaxanthin 

Violaxanthin is a lipophilic epoxy carotenoid and a light energy scavenger with biological activities such as antioxidation and anti-inflammation. Violaxanthin exists in photosynthetic eukaryotes including higher plants and participates in the xanthophyll cycle. As a component of the xanthophyll cycle, violaxanthin can be synthesized from zeaxanthin under the catalysis of epoxidase and scavenge excess light energy in photosynthetic eukaryotes^[1].

Violaxanthin is biosynthesized from zeaxanthin (HY-120318) via antheraxanthin in photosynthetic eukaryotes, including higher plants, under the action of zeaxanthin epoxidase (ZEP), and participates in the xanthophyll cycle to dissipate excess light energy^[1].
Violaxanthin is sensitive to light and heat, requiring strict light-shielding operations. For experimental concentrations, references of analogous xanthophylls (Lutein/Zeaxanthin) can be consulted.
