Main Methods:

• Methanol extraction of Smilax bracteata rhizomes.
• Chromatographic separation techniques for isolation of compounds.
• Spectroscopic methods (e.g., NMR, MS) for structural elucidation.

Main Results:

• Isolation of six new phenolic compounds: five flavans and one dihydrobenzofuran derivative.
• Identification of three new fructofuranosyl glycosides.
• Characterization of five known compounds alongside the new discoveries.
• Structural determination of all isolated compounds through comprehensive spectral analysis.

Conclusions:

• The study successfully identified novel phenolic compounds from Smilax bracteata.
