Abstract:

Chemotaxonomic studies of the Myrtaceae have previously centred on chemotypes within species, using phenolics and volatile leaf oils. However, few genera have been studied in any detail. A wide-ranging survey of polyhydroxyalkaloids (PHAs) in the Myrtaceae led to the identification of fourteen PHAs from three structural subclasses. These compounds have a non-random distribution within the Myrtaceae. The genera of the three subtribes of the Myrtoideae differ in their PHA profiles. PHAs are almost ubiquitous and very diverse in the Eugeniinae and are also diverse in both species of the genus Luma.
