General Introduction Lignans are a diverse group of natural polyphenolic compounds found primarily in plants. They are a subgroup of non-flavonoid polyphenols, derived from the oxidative coupling of two phenylpropanoid units (C6-C3). Lignans are biosynthesized from phenylalanine through the shikimic acid pathway. They are structurally characterized by a 2,3-dibenzylbutane skeleton, forming a unique class of…
Definition of Phenylpropanoids: Phenylpropanoids are a large class of plant secondary metabolites derived from the amino acid phenylalanine through the phenylpropanoid pathway. These compounds are characterized by a basic structure of a C6-C3 skeleton, which consists of a benzene ring (C6) linked to a three-carbon propene chain (C3). Phenylpropanoids are diverse in structure and function,…
