A new xanthone from Halenia elliptica D. Don.
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 (13)C NMR spectroscopic data of 2,3,4,5-tetramethoxyxanthone-1-O-gentiobioside (2) were reported for the first time.
