Compound 7(cis-glanduloidin D) was found to possess acis-p-coumaroyl moiety instead of atrans-p-coumaroyl moiety as in
6. The NMR data of these two compounds were very similar to one another. In the 1 H NMR spectrum, a smaller J value was
observed between H-7″/H-8″(12.6 Hz), indicating the double bond at C-7/C-8 to have acis-configuration. Analysis of the 1D
and 2D NMR data confirmed the structure of 7as (1S,2S)-2-hydroxycyclohexyl-2′-O-cis-p-coumaroyl-β-D-glucopyranoside.
