A new xanthone from Halenia elliptica D. Don

Abstract

A new xanthone, 1,5-dihydroxy-2,3,4-trimethoxyxanthone (1), together with 15 known compounds (2–16), was isolated from an ethanolic extract of Halenia elliptica D. Don. Their structures were elucidated by spectroscopic methods. Among the known compounds, the ¹³C NMR spectroscopic data of 2,3,4,5-tetramethoxyxanthone-1-O-gentiobioside (2) were reported for the first time.

Keywords:
