Phenolic, megastigmane, nucleotide, acetophenon and monoterpene glycosides from Phlomis samia and P-carica
Phytochemical investigations on the aerial parts of Phlomis samia resulted in the isolation of a simple phenolic glucoside, 2;6-dimethoxy-4-hydroxyphenol-1-O-beta-D-glucopyranoside (1); a megastigmane glucoside, phlomuroside (=3-hydroxy-5,6-epoxy-beta-ionol-9-O-beta-D-glucopyranoside) (2); and a nucleotide glycoside, uridine (3). From the aerial parts of P. carica, the same phenolic glucoside, 2,6-dimethoxy-4-hydroxyphenol-1-O-beta-D-glucopyranoside (1); as well as an acetophenon glucoside, picein (4); and 2 monoterpenoid glucosides, -betulalbuside A (5) and 1-kydroxylinalQyl-6-O-beta-D-glucopyranoside (6)-were isolated and identified. The structure elucidation of the isolates was based on spectroscopic evidence.
