Abstract
The chemical composition of the essential oils from the leaves of Brassica rapa Linn. var. perviridis Bailey has been investigated by GC and GC–MS. The leaf essential oil was found to contain 48 volatile components, representing 94.0–96.6% of the oil, which were characterized. The main constituents were 3-butenylisothiocyanate (1.4–29.2%), 4-pentenyl isothiocyanate (8.2–23.5%), 2-methyl 5-hexenenitrile (1.3–16.8%), 2-phenylethyl isothiocyanate (7.0–13.7%) and phytol (6.1–23.5%). The essential oil from the leaves of B. rapa was characterized by a high content of sulphur- and nitrogen-containing compounds. Copyright © 2004 John Wiley & Sons, Ltd.
