Two new C-methyl flavonoids, diplomorphanins A (1) and B (2) were isolated from the aerial parts of Diplomorpha canescens ( Meisn.) C. A. Meyer along with a known compound, farrerol 7-O-β-dglucopyranoside (3). Structures of these compounds were determined on the basis of spectroscopic data.

One new C-methyl flavanone glucoside, farrerol 4′-O-β-D- glucopyranoside (1) was isolated from the aerial parts of Diplomorpha canescens (MEISN.) C. A. MEYER. Fourteen known phenolic compounds such as farrerol (2), luteolin 7-methyl ether 5-O-β-D-glucopyranoside (3), (-)-pinoresinol (4), (-)-lariciresinol (5), (-)-dihydrosesamin (6), (±)-dehydrodiconiferyl alcohol (7), rutarensin (8), umbelliferone (9), coniferyl aldehyde (10), sinapyl aldehyde (11), p-coumaric acid methyl ester (12), p-hydroxybenzaldehyde (13), p-hydroxyacetophenone (14) and syringaldehyde (15) were also isolated for the first time from this plant. Structure of 1 was determined on the basis of spectroscopic data including two dimensional (2D)-NMR, circular dichroism (CD) and by the application of Klyne's rule.
