AbstractColucons A (1) and B (2), new prenylated flavanones, isolated from the EtOAc-soluble sub-fraction of the whole plant of Colutea armata Hemsl. & Lace along with four known compounds, namely, kenusanone J (3), hesperetin (4), tyrosol (5) and syringaldehyde (6), were reported for the first time from the species armata. Their structures were elucidated by spectroscopic techniques including 1H and 13C NMR (distortionless enhancement by polarization transfer), and 2D NMR experiments. Compounds 1–3 showed significant antifungal activity against Pseudallescheria boydii, Aspergillus niger, Trichophyton mentagrophytes, Macrophomina phaseolina and Candida glabrata, while compound 4 showed moderate antifungal activity.
