Phenylethanoid glycosides of Sesamum indicum.

abstract：:Acylation is a prevalent chemical modification that to a significant extent accounts for the tremendous diversity of plant metabolites. To catalyze acyl transfer reactions, higher plants have evolved acyltransferases that accept beta-acetal esters, typically 1-O-glucose esters, as an alternative to the ubiquitously oc...
