The skimmiwallinols—minor components of the epicuticular wax of Cocos nucifera

Four new skimmiwallinol derivatives, isoskimmiwallinol acetate ( 4 ), skimmiwallinol acetate ( 5 ), isoskimmiwallinone ( 6 ) and skimmiwallinone ( 7 ), along with the previously isolated major components isoskimmiwallin ( 2 ) and skimmiwallin ( 3 ), have been found in the wax extract of pinnae from Cocos nucifera . Metabolites 4 and 5 were obtained as an inseparable mixture and identified by analysis of spectroscopic data and chemical correlation with 2 and 3 , respectively. Metabolites 6 and 7 were identified by GC co‐injection with the corresponding synthetic derivatives prepared from 4 and 5 . Copyright © 2007 John Wiley & Sons, Ltd.
