Abstract: | As a result of the surveying of 13 taxa of the genus Diplotaxis, it was found that their leaf flavonoids are flavonol glycosides derived from either kaempferol, quercetin and isorhamnetin. Multivariate analysis of these flavonoid data of taxa suggest a close chemotaxonomic affinity. On the basis of their chemical composition the taxa relationships are discussed. The allopolyploid origin of D. muralis with D. tenuifolia and D. viminea as parentals is strongly supported by chemical evidence. |
