The chemical composition of volatile oils from two Myrtaceae species, Myrceugenia myrcioides and Eugenia riedeliana, both native from the Brazilian Atlantic Rain Forest, was analyzed by GC-MS. Acetylcholinesterase inhibitory activity was colorimetrically evaluated for these oils. For M. myrcioides, monoterpene hydrocarbons represented the major class in the volatile oil, with α-pinene as the mo...

The Myrtaceae plants are cultivated for their edible fruits and folk medicinal uses.

The leaves of Eucalyptus robusta Smith (Myrtaceae) are used in China to prepare the anti-malari­ al traditional medicine “Da Ye An” [1], Previous work on the extract of the leaves has yielded the bisphloroglucinol robustaol [21 as well as the robustadials A and B [3], The known phenols euglobal la, and Ia2, originally reported from E. globulus [4], were also isolated [3]. In a broad screening f...

Solioccasus polychromus gen. & sp. nov., the most brightly colored hypogeous fungus known, is described from Papua New Guinea and tropical northern Australia south into subtropical forests along the Queensland coast and coastal mountains to near Brisbane. Phylogenetic analysis of molecular data places it as a sister genus to Bothia in the Boletineae, a clade of predominantly ectomycorrhizal bol...
