Glycopentosides D – F, Three New Phenolic Glycosides from Glycosmis pentaphylla

A phytochemical investigation of the BuOH-soluble fraction of the EtOH extract from the stems of Glycosmis pentaphylla resulted in the isolation of three new phenolic glycosides, glycopentosides D–F (1–3, resp.). Their structures were determined by using spectroscopic analysis including UV, 1H- and 13C-NMR, DEPT, COSY, ROESY, HMBC, HSQC, HR-ESI-MS, and acid hydrolysis.
