Definitions

Cuticula

Tough, flexible, non-mineral, hydrophobic, waxy cover layer that is produced by plant epidermal cells.

Terpenoids

Class of specialized plant metabolites that is derived from isoprene and contains oxygen functions.

Structure and Occurrence

Plant leaves and petals are covered by cuticular waxes that are formed by organic substances that are not water soluble and thus can form non-wet-table films (Holloway and Jeffree 2016). Cuticular waxes can not only contain alkanes, alkane alcohols, alkane acids, and their esters, so-called wax esters, but also di- and triterpenes from the isoprenoid pathways (Gütz 1989). More detailed studies on Prunus laurocerasus suggest that the epicuticular wax layer may be composed of higher amounts of alkanes, whereas triterpenes dominate in the intracuticular layer of the leaf cuticle (Jetter et al. 2000). The most widely employed sample preparation method, rinsing leaves with nonpolar organic solvents, does not differentiate between...
