Abstract

A new compound, (-)-S-allyl-2-thiooxazolidone (napoleiferin) has been isolated from rape (Brassica napus L. var. oleifera) and its presence demonstrated by chromatographic methods in turnip (B. campestris L.) and swede (B. napus L. var. napobrassica). Its structure was established with the aid of NMR, U.V. and i.r. spectral data. ORD data indicate a similar absolute configuration to that of goitrin isolated from the same tissue. Evidence suggests a new glucoside, 2-hydroxy-4-pentenyl-glucosinolate, is present in fresh tissue.
