When tested for ornithine and arginine decarboxylases, pyrrolizidine alkaloid-bearing Senecio riddellii, S. longilobus (Compositae), and Crotalaria retusa (Leguminosae) plants exhibited only ornithine decarboxylase activity. This contrasts with previous studies of four species of pyrrolizidine alkaloid-bearing Heliotropium (Boraginaceae) in which arginine decarboxylase activity was very high re...

Two new triterpenoid saponins have been isolated from leaves and flowers of Crotalaria madurensis Wight&Arn named; sophradiol 3-O-β-D-C1-glucopyranosyl-(1''→4')-O-β-DC1 glucuronopyranoside (3) and sophradiol 3-Oα-LC4rhamnopyranosyl (1'''→4'')-O-ß-D-C1 glucopranosyl-(1''→6')-O-ß-DC1-glucopyranoside (4) beside myo-inositol (1) and three other triterpene saponin their structures were established a...

The combined effect of cyclophosphamide (CTX) and extracts of six patients belonging to Crotalaria and Senecio genera was assessed on experimental transplantable S180 (both ascitic and solid forms) tumour. Successive petroleum ether and methanolic extracts from these plants were obtained. The combined administration of CTX and petroleum ether extract of C. albida and the methanolic extracts of ...

A small group of six morphologically related seed beetles (Coleoptera: Chrysomelidae: Bruchinae) belonging to the Conicobruchus genus is reviewed. Species in this group for which host-plants are known feed on various species of Crotalaria (Fabaceae, Crotalarieae). Here we provide diagnoses and a dichotomous key for all six species. The following synonymies are proposed: Conicobruchus cicatricos...
