| Abstract: | The twigs of Phebalium anceps yielded the common furocoumarins psoralen, bergapten and xanthotoxin whereas the leaves of P. coxii and P. ralstonii gare only 8-prenylated 7-methoxycoumarins. From R coxii murrangatin and murralongin were obtained whilst R ralstonii yielded both of these compounds and another coumarin, the novel 7-methoxy-8-(2-acetoxy-3-methyl-1oxobut-2-enyl)-coumarin. The chemotaxonomic implications of these results are discussed. |
