Structural Elucidation of Dendranthemosides A and B: Two New β-Ionone Glucosides fromDendranthema shiwogiku

Abstract
From the n-BuOH soluble fraction of an MeOH extract of Dendranthema shiwogiku, two new β-ionone glucosides and roseoside were isolated, the structures of the new compounds elucidated were 2 and 3, respectively, on the basis of spectroscopic data and the results of an enzymic hydrolysis of 2.
