Abstract

In addition to rare phenylethanoid triglycosides, myricoside and its dimetylether derivative serratumoside A {3-hydroxy,4-methoxy-beta-phenylethoxy-O-beta-D-apiofuranosyl-(1 --> 3)-alpha-L-rhamnopyranosyl( (1 --> 3)- 4-O-feruloyl-beta-D-glucopyranoside}, a new phenylethanoid glycoside, myricoside-3''''-O-methylether {3,4-dihydroxy-beta-phenylethoxy-O-beta-D-apiofuranosyl-( 1 --> 3)-alpha-L- rhamnopyranosyl-( 1 --> 3)- 4-O-feruloyl-beta-D-glucopyranoside} along with a new neolignan glucoside, (7S, 8R)- dehydroconiferyl alcohol-8- 5'-dehydroconiferyl aldehyde 4-O-beta-D-glucopyranoside were isolated from the aerial parts of Phlomis oppositiflora. The structures of the new compounds were identified by means of spectroscopic (UV, IR, 1D- and 2D-NMR, and LC-ESIMS) methods.
