Two phenylethanoid triglycosides, phlinosides C 1 and E 2 were isolated from the methanolic extract of the overground parts of Phlomis physocalyx. On the basis of spectroscopic evidence the structures of the isolated compounds were determined as 3,4-dihydroxy-β-phenylethoxy- O-α-L-rhamnopyranosyl- 1→2 -α-L-rhamnopyranosyl- 1→3 - 4-O-caffeoyl-β-D-glucopyranoside and 3,4-dihydroxy-β-phenylethoxy- O-α-L-rhamnopyranosyl- 1→2 -α-L-rhamnopyranosyl- 1→3 -4-O-feruloyl- β-D-glucopyranoside, respectively. The structure elucidation of the phenylethanoid glycosides 1 and 2 are explained in detail. This is the second report for the isolation of these phenylethanoids from a member of the genus Phlomis.
