Three new compounds: Graviquinone (1), cis-3-hydroxy-5-pentadecylcyclohexanone (2), and methyl 5-ethoxy-2-hydroxycinnamate (3), and thirty-eight known compounds were isolated and identified from the leaves of Grevillea robusta. The structures of these compounds were determined by spectroscopic and chemical transformation methods. Graviquinone (1) showed the strongest cytotoxicity against MCF-7,...

The tanaid genus Hexapleomera has long been considered to be monotypic, comprising a cosmopolitan species predominantly commensal on turtles, or, more rarely, manatees. Recent discovery of material of a distinct species of Hexapleomera living on the hulls of yachts in south-west England encouraged re-assessment of the literature on this taxon, and re-examination of free-living benthic material ...

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...

Rainfall interception losses from an agroforestry system in semi-arid Kenya comprising Grevillea robusta and maize were measured over a period of 33 months. These measurements showed that interception was slightly higher (10.2%) under trees with no maize understorey, than in the intercropped treatment (9.8%), and was directly related to the degree of tree canopy cover. Interception estimates us...
