Abstract
Three new dibenzoylmethane derivatives were isolated from petrol extra cts of the roots of Lonchocarpus latifalius and L. muehlbergianus. Mol ecular structures were determined from spectroscopic data, especially NMR techniques. An alkyl group bonded to the central carbon (C-8) of a natural dibenzoylmethane, had not been found before. Spectral data an alysis suggested a preponderance of the respective diketotautomers. (C ) 1997 Elsevier Science Ltd.
