GC-MS analysis of volatile hydrolysis products from glucosinolates in Farsetia aegyptia var. ovalis

Twenty-two volatile glucosinolate hydrolysis products from seeds and leaves of Farsetia aegyptia var. ovalis were identified and quantified using both natural autolysis and exogenous myrosinase, followed by GCMS. The 22 isothiocyanate thiocyanate, epithioalkane nitrile and nitrile hydrolysis products identified can be rationalized, assuming 13 glucosinolates in the seeds and 12 in the leaves. Among the volatile hydrolysis products observed, those derived from allylglucosinolates and 3-methylsulphinylpropylglucosinolate (glucoiberin) were prominent. Copyright © 2003 John Wiley & Sons, Ltd.
