A new cysteine sulfoxide, (SSRC)-S-(3-pentenyl)-L-cysteine sulfoxide (I), was identified from the seeds of Allium cepa var. tropeana, together with the known methiin, etiin, alliin, isoalliin, propiin, and butiin. The structure of I was established by anal. of its phys. and spectroscopic data. The antioxidant activity of an ext. contg. cysteine sulfoxides and I 1 was evaluated using the FRAP and DPPH tests.

Abstract
A new cysteine sulfoxide, (SSRC)-S-(3-pentenyl)-L-cysteine sulfoxide (I), was identified from the seeds of Allium cepa var. tropeana, together with the known methiin, etiin, alliin, isoalliin, propiin, and butiin. The structure of I was established by anal. of its phys. and spectroscopic data. The antioxidant activity of an ext. contg. cysteine sulfoxides and I 1 was evaluated using the FRAP and DPPH tests.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
