Dynamic changes of phytochemical profiles identified key points of flaxseed capsule maturation for lignan accumulation

Flaxseed is a rich source of lignans and hydroxycinnamic acids. In this study, the variation of lignans, hydroxycinnamic acids, and the transcription levels of genes involving lignan biosynthetic pathway of flaxseed capsules at different mature stages was investigated. Secoisolarisiresinol diglucoside showed a sharp increase during the early rapid growing period, with about a 24.7-fold enhancement till S3, followed a slower increasing rate and...
