Phenolic glycosides from Phlomis lanceolata (Lamiaceae)

Abstract

Preparative reversed-phase HPLC analyses of the methanol extract of the aerial parts of Phlomis lanceolata afforded three phenolic glycosides including a flavonol glycoside, peterin (1), and two phenylethanoid glycosides, viridoside (2) and peteroside (3). Compounds 1 and 3 are novel natural products. The structures of all three compounds were elucidated by spectroscopic means.
