Demonstration of long-chain n-alkyl caffeates and delta7-steryl glucosides in the bark of Acacia species by gas chromatography-mass spectrometry.


The GC-MS identification of several abundant long-chain aliphatic n-alkyl caffeates, together with other phydroxycinnamic acid esters, in the dichloromethane extracts of the bark of Acacia dealbata and A. melanoxylon, is reported. In addition, the unambiguous differentiation between two delta7-steryl glucosides (namely, spinasteryl glucoside and… (More)
