• Isolation of compounds using chromatographic techniques.
• Structure elucidation using spectroscopic methods, including Nuclear Magnetic Resonance (NMR) and Mass Spectrometry.

Main Results:

• Isolation of a new xanthone, 1,5-dihydroxy-2,3,4-trimethoxyxanthone (1).
• Isolation of 15 known compounds (2-16) from the extract.
• Reporting of the (13)C NMR spectroscopic data for 2,3,4,5-tetramethoxyxanthone-1-O-gentiobioside (2) for the first time.

Conclusions:

• The ethanolic extract of Halenia elliptica is a rich source of xanthone derivatives.
• The identification of a new xanthone expands the known chemical diversity of this compound class.
• The reported spectroscopic data enhances the characterization of known natural products.
