End Date: Sep 30, 2010
General procedures for isolation of secondary metabolites will be employed such as solvent extractions, distillations, column chromatography and thin layer chromatography. Identification of biologically active compounds will be done using spectroscopic methods (UV, IR, MS, NMR). Extracts, fractions, and pure compounds will be tested for phytotoxic, antifungal, algaecidal and/or termiticidal activities. Phytotoxicity, antifungal and algaecidal assays being carried out routinely at NPURU will be utilized. Activity against the Formosan subterranean termite will be performed at the USDA-ARS, Formosan Subterranean Research Unit, New Orleans, LA. Biosynthetic studies will be performed by feeding with 13C-labelled precursors and incorporation will be determined by 13C-NMR spectroscopy. Molecular biology experiments will be performed using standard protocols.
