TRANSFER OF BIPIPERIDYL AND QUINOLIZIDINE ALKALOIDS TO VISCUM-CRUCIATUM SIEBER (LORANTHACEAE) HEMIPARASITIC ON RETAMA-SPHAEROCARPA BOISSIER(LEGUMINOSAE)
Cm. Cordero et al., TRANSFER OF BIPIPERIDYL AND QUINOLIZIDINE ALKALOIDS TO VISCUM-CRUCIATUM SIEBER (LORANTHACEAE) HEMIPARASITIC ON RETAMA-SPHAEROCARPA BOISSIER(LEGUMINOSAE), Journal of chemical ecology, 19(10), 1993, pp. 2389-2393
Plant material of Viscum cruciatum Sieber contains bipiperidyl (ammode
ndrine) and quinolizidine alkaloids (lupanine, 5,6-dehydrolupanine, re
tamine, cytisine, N-methylcytisine). This plant obtains the alkaloids
by root parasitism on Retama sphaerocarpa Boissier (host plant). These
results have important implications for Viscum ecology, for the study
of herbivores that are Viscum specialists, and in the development of
systems for the investigation of the role of alkaloids as plant defens
es.
