A New Sideroxylonal from Eucalyptus melliodora

Abstract

Sideroxylonal C (3), (2RS,3RS,4RS)-2-(3,5-diformyl-2,4,6-trihydroxyphenyl)-5,7-dihydroxy-3-(1-methyl- ethyl)-4-(2-methylpropyl)chroman-6,8-dicarbaldehyde, was isolated from Eucalyptus melliodora leaf, and its structure determined by spectroscopic methods.

Qualitative and Semi‐quantitative Analysis of Phenolics in Eucalyptus globulus Leaves by High‐performance Liquid Chromatography Coupled with Diode Array Detection and Electrospray Ionisation Mass Spectrometry

“…Sideroxylonal is very well described in E. globulus leaves (O' Reilly-Wapstra et al, 2004) and in fruit or leaves of other Eucalyptus species (Eschler and Foley, 1999;Neve et al, 1999;Close et al, 2001;Wallis et al, 2003).…”

Phloroglucinol compounds of natural origin

“…Sideroxylonals A-C (536-538) are dimeric phloroglucinol compounds found in the leaves and flower buds of some species of Eucalyptus. 355,356 Sideroxylonals differ from each other in stereochemistry at C-7, C-10 , and C-7 . These compounds have a wide range of biological effects, e.g.…”

Spectrometric prediction of secondary metabolites and nitrogen in fresh Eucalyptus foliage: towards remote sensing of the nutritional quality of foliage for leaf-eating marsupials

“…We scanned cineole in a liquid cuvette in the transport module. Sideroxylonal A was extracted and purified as previously described (Eschler and Foley 1999) and about 1 g of the off-white crystals was placed directly into a small spinning cup sample holder for presentation to the spectrometer.…”
