Abstract

Two new methoxychalcones, kukulkanins A (2',4'-dihydroxy-3',4-dimethoxychalcone) and B (2',4',4-trihydroxy-3'-methoxychalcone), were isolated by flash chromatography of extracts of small branches of Mimosa tenuefolia. The compounds were identified using ir, nmr, uv, and mass spectroscopy, and their structures were confirmed by X-ray crystallography.
