Chemical Constituents of Micromelum Minutum and Acronychia Laurifolia (Rutaceae)

A chemotaxonomic investigationon the leaves and stems of Micromelum minutum (Rutaceae), has resulted in the isolation of six components. The structure of these compounds was elucidated by means of spectroscopic methods including by the extensive used of various NMR techniques and al so comparison wi...
