Abstract

The structure of Tiliroside from Tilia argentea has been shown to be Kaempf erol– 3–O–(6"–O–p– coumaroy 1–β–D–glucopyranoside) by ¹³C–NMR spectroscopy. A reassignment of the sugar carbon signals in the ¹³C–NMR spectrum of the hexahydroindolizine alkaloid Ipomine leads to the structure revision as Ipalbidinyl–(6"–O–p––oumaroyl–β–D–glucopyranoside).
