Abstract

Eburneolins A (1) and B (2), new withanolide glucosides, have been isolated from the n-butanolic fraction of the 75% methanolic extract of aerial parts of Tricholepis eburnea. Their structures were elucidated through spectroscopic analysis including ESI-MS, 2D NMR and acid hydrolysis.

Keywords: Asteraceae; Tricholepis eburnea; eburneolin A; eburneolin B; withanolide glucosides.
