First report of n-alkylresorcinol occurrence in the Euphorbiaceae family: Mercurialis perennis L

Dog's mercury (Mercurialis perennis L., Euphorbiaceae) is a perennial herb, particular important in phytotherapy and anthroposophic medicine. Therefore, detailed studies on the phytochemical composition are of great interest. A comprehensive GC/MS screening of chloroform extracts obtained from aerial and root parts from M. perennis revealed several homologues of n-alkylresorcinols (ARs). GC/MS investigations of silylated samples in combination with LC/(APCI)MSn studies showed three major ARs with odd numbered aliphatic side chains (C19 : 0, C21 : 0, and C23 : 0), accompanied by small amounts of C15 : 0, C17 : 0,…
