Chemical constituents and biological studies of the leaves of Grevillea robusta.
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,...
متن کاملGrevillosides A-F: glucosides of 5-alkylresorcinol derivatives from leaves of Grevillea robusta.
From a MeOH extract of leaves of Grevillea robusta, seven compounds (1-7) were isolated. One known compound (7) was identified with a benzyl glucoside, icariside F2. The structures of the six of these, named grevillosides A-F (1-6), were elucidated on detailed inspection of one- and two-dimensional NMR spectroscopic data as glucosides of 5-alkylresorcinols.
متن کاملAllergic contact dermatitis from exposure to Grevillea robusta in New Zealand.
There are a number of reports in the literature of allergic contact dermatitis as a result of exposure to the sawdust and plant parts of Grevillea robusta. While this tree is prevalent in New Zealand, there seems to have been no previous published accounts of contact dermatitis, although anecdotal evidence indicates that such cases may be common. Two brief case reports are provided regarding se...
متن کاملDevelopment and characterization of microsatellite loci in Grevillea robusta
Background Grevillea robusta is a native tree to the subtropical coastal regions of northern New South Wales and southern Queensland in Australia. In Brazil, Embrapa Forestry and its partners have established many provenance/progeny tests to increase the species genetic basis and aim to implement a breeding program to improve timber production. Genetic variability of these tests has been monito...
متن کاملProductivity, microclimate and water use in Grevillea robusta-based agroforestry systems on hillslopes in semi-arid Kenya
This paper describes a multi-disciplinary project to examine the changing interactions between trees and crops as the trees in semi-arid agroforestry systems establish and mature; the project is one of the most detailed and highly instrumented long-term studies of tree and crop growth, system performance, resource capture, hydrology and microclimate ever carried out within an agroforestry conte...
