Phenalenones from Strelitzia reginae

Abstract

Phytochemical analysis of rhizomes of Strelitzia reginae resulted in the isolation and identification of an unusual new (1) and four known phenalenone-type compounds, which were identified using MS and NMR spectroscopic techniques. The occurrence of phenalenones in Strelitziaceae, which has been established for the first time, is of chemotaxonomic interest.
