Coumarins from three phebalium spp

Coumarins from three phebalium spp

Biochemical Systematics & Ecology 16(7-8): 631-634

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