The distribution of cucurbitacins in seeds and growing plants of Iberis umbellata L. has been investigated. The testas of 'Giant Pink', 'Purple', 'Crimson' and 'Iceberg' (Dutch) strains of Iberis umbellata contain Cucurbitacin B with traces of D and E. Seeds of 'Iceberg' (Danish) strain were exceptional in containing cucurbitacins E and I but no B, and this strain was also distinguished by larger redder seeds and by testas which were not readily separable into two layers. Cucurbitacins are rare in other crucifers but they are present in I. gibraltarica L., I. sempervirens L. and Lepidium sativum L.
