Abstract
Capparis ovata var.
palaestina Zoh.,
C. spinosa var.
aegyptia Boiss. and
C. spinosa var.
deserti Zoh., were investigated for glucosinolates. Glucoiberin, glucocapparin, sinigrin, glucocleomin, glucocapangulin, glucobrassicin and neoglucobrassicin, in addition to two others, were isolated. Four of these
viz. glucoiberin, sinigrin, glucobrassicin and neoglucobrassicin were detected for the first time in
Capparis species. Comparative chromatographic analyses of the glucosinolates of the plants examined revealed qualitative differences.
