Abstract

From the aerial parts of Phlomis tuberosa a new iridoid glucoside, chlorotuberoside was isolated together with five known iridoid glucosides, lamalbide, shanzhiside methyl ester, 7-epi-phlomiol (= ployoside I), sesamoside and 5-deoxysesamoside. Two known phenylethanoid glycosides, forsythoside B, and decaffeoylacteoside, three known neolignan glycosides, dehydrodiconiferyl alcohol 9'-O-beta-D-glucopyranoside, dihydrodehydrodiconiferyl alcohol 9-O-beta-D-glucopyranoside and dihydrodehydrodiconiferyl alcohol 9'-O-beta-D-glucopyranoside, one flavone glycoside, luteolin 7-O-beta-D-glucopyranoside, as well as P-sitosterol 3-O-beta-D-glucopyranoside and 1-methyl-O-beta-D-glucopyranoside were also obtained and characterized. The structures of the isolates were elucidated on the basis of spectroscopic data. The three known phenylethanoid glycosides, verbascoside, leucosceptoside A and martynoside were identified by TLC comparison with authentic compounds.
