### Volatile Constituents of Kernel Oil  
The volatile constituents of kernel oil are composed of a total of 65 different compounds consisting of 24 distinct classes including 13 alcohols, 14 aldehydes, 5 carboxylic acids, 4 phenols, 4 sesquiterpene, 4 lactones, 2 pyridines, 2 saturated fatty acids, 2 ketones, and an alkylbenzene, alkyne, cyclic ketone, cycloalkene, diene, diketone, furan, glycol ether, guaiacol, halogenated benzene, medium-chain fatty acid, monoterpene, phenolic compound, and a terpene, as well as a vinyl aromatic hydrocarbon. Alcohols and aldehydes dominated (42%) the compounds (Table 1). \begin{table}
