Volatile Constituents of Leaves and Stems of Nasturtium officinale R. Br.

Abstract

Volatile constituents of the dried leaves and stems of Nasturtium officinale R. Br. collected after hydrolysis were analyzed by GC and GC/MS. The major volatile constituents of the leaves were 2-phenylethyl isothiocyanate (72.9%), pulegone (8.0%), heptyl isothiocyanate (4.9%) and 4-phenylbutyl isothiocyanate (3.2%), while the main volatile constituents of the stems were 2-phenylethyl isothiocyanate (83.5%), 4-phenylbutyl isothiocyanate (6.9%), pulegone (2.2%) and sec-butyl isothiocyanate (1.9%).
