Abstract
Plant metabolites characterisation is an arduous challenge due to their structural diversity as a result
of complicated biosynthetic pathways. These metabolites are not only important for metabolic events
description but are also harnessed as valuable nutraceuticals. The detection and description of important
plant tissue metabolome such as oil palm spear leaf can be carried out using a broad-range, non-targeted
analytical tool such as mass spectrometry (MS). Identification of oil palm spear leaf constituents such as
carboxyl group- and sugar- containing metabolites was facilitated by tandem mass spectrometry (MS/
MS) with neutral loss information of 44 and 162 amu. A total of 13 metabolites ranging from carboxylic
acids, catechins, phenolic acid glycosides and a stilbenoid were characterised in this manner and the results
presented here demonstrated the usefulness of MS in characterising metabolites in a complex sample such
as oil palm spear leaf tissue.
