✦ Synopsis

The influence of y and b-irradiation and storage time on the composition of the volatile compounds in basil (Ocimum basilicum L.) has been examined. Dried basil was exposed to yand P-rays at the doses of 3, 10 and 30 kGy, and volatile components were isolated by simultaneous distillation-extraction in a Likens-Nickerson apparatus. Sixty-five compounds were identified in the extracts and quantitatively evaluated; the major component was methylchavicol (88%). Quantitatively important volatile compounds in basil were found to be reduced during storage. Only slight (not significant) differences in the content of some constituents, including methylchavicol, tnethyleugenol and 1.8-cineole were found between irradiated and non-irradiated basil herb.
