ChemInform Abstract
Enzymatic hydrolysis of salicortin (Ia) releases glucose while its aglycone (Ib) is decarboxylated and undergoes an unusual fragmentation- recombination reaction, leading to (IV) via a postulated ortho-quinone methide (II). The decomposition of (Ia) is accompanied by a slow time- dependent irreversible inhibition of the enzyme.
