Cablinosides A and B, Two Glycosidic Phenylacetic Acid Derivatives from the Leaves of Pogostemon cablin

Abstract A pair of new glycosidic epimers, cablinosides A ( 1a ) and B ( 1b ) were isolated from the leaves of Pogostemon cablin . The structures with absolute configurations of 1a and 1b were elucidated by extensive NMR investigation, and quantum chemical CD calculations. The epimer mixture 1 showed moderate α ‐glucosidase inhibitory activity and no significant cytotoxic activity against HepG2 cells.
