title: Serruloside and Serrulatoside, two New Iridoid Glycosides from Penstemon serrulatus1.
abstract: From leaves of PENSTEMON SERRULATUS Menz. two new iridoid glycosides have been isolated. Both glycosides have the same aglycon part, but differ in their carbohydrate moieties. The structure of serru-loside (penstemidaglucon-11- O-beta- D-ribohexos -3-uloside) and serrulatoside (penstemidaglucon-ll- O-beta-4'-desoxyaltropyranosido-6'- O-beta- D-glucopyranoside) was established by spectroscopic methods (mainly (1)H- and (13)C-NMR) and comparison with known compounds.
