Objective:
To study the chemical constituents of Humulus scandens.
Methods:
The compounds were isolated by column chromatography on silica gel and Sephadex LH-20. The structures were identified by means of IR, 1H-NMR,13C-NMR and MS analyses.
Results:
Seven compounds were isolated and identified as friedelanone (I), cis-asarone (II), epifriedelanol (III), stigmasta-4-ene-3,6-dione (IV), gamma-sitosterol (V), n-hexadecanoic acid (VI), and linoleic acid (VII), respectively.
Conclusion:
All compounds are isolated from this species for the first time and compounds I - V are obtained from this genus for the first time.
