A new iridoid from Scrophularia auriculata ssp. pseudoauriculata.
A new iridoid glycoside, scrovalentinoside (1), was isolated from the MeOH extract of the aerial parts of Scrophularia auriculata L. ssp. pseudoauriculata. The structure of the new compound 1 was elucidated as 6-O-(2", 3"-di-O-acetyl-4"-O-p-methoxy-cinnamoyl)-alpha-L-rhamnopyranosyl catalpol by spectroscopic methods. The known iridoid glycoside, scropolioside A; two saponins, verbascosaponin A and verbascosaponin; and the phenylethanoid glycoside, verbascoside, were also isolated.
