Neolignan glucosides from Phlomis chimerae Boiss.
From the aerial parts of the plant Phlomis chimerae, a new neolignan glucoside, (-)-4-O-methyldihydrodehydrodiconiferyl alcohol-9'-O-beta-D-glucopyranoside (1) was characterized along with the known neolignan glucosides, (-)-4-O-methyldehydrodiconiferyl alcohol-9'-O-beta-D-glucopyranoside (= longifloroside A) (2) and (-)-dihydrodehydrodiconiferyl alcohol-9-O-beta-D-glucopyranoside (3). The structure of the new compound was established on the basis of spectroscopic evidence.
