Abstract

A bioassay-guided chemical study of a methanolic extract of fresh leaves of <i>Luma chequen</i> led to the isolation of lumaflavanones A (<strong>1</strong>), B (<strong>2</strong>) and C (<strong>3</strong>) whose structures are proposed on the basis of NMR spectroscopic data. The structure of lumaflavanone A was confirmed by X-ray analysis. Antifeedant (<i>Spodoptera littoralis</i>), brine shrimp (<i>Artemia salina</i>) and fungistatic (<i>Botrytis cinerea</i>) bioassays showed that while <strong>3</strong> was the most active in the first two assays the mixture of <strong>1</strong> and <strong>2</strong> was more effective as a fungistatic. <p>
