Abstract

The structuers of belamcandols A (1) and B (2) isolated from the seeds of Belamcanda chinensis have beenassigned to 2, 4-dimethyoxy-6-((Z)-10'-pentadecenyl)phenol and 1-O-methyl-5-((Z)-10'-pentadecenyl)resorcinol, respectively, based on spectroscopic data and chemical degradation. Belamcandol A inhibits 5-ilpoxygenase activity at IC₅₀ 0.60 μM.
