Treatments for breaking dormancy of the crotalaria seeds (Crotalaria ochroleuca)

Flavonoids of Crotalaria sessiliflora.

Phytochemical investigation of the whole plants of Crotalaria sessiliflora L. led to the isolation of four flavonoids. The structures of these compounds were identified as 2',4',5,7-tetrahydroxyisoflavone (1), 2',4',7-trihydroxyisoflavone (2), 4',7-dihydroxyflavone (3), and isovitexin (4) using spectroscopic analysis. Among these, compounds 2, and 3 have not been reported from Crotalaria specie...

Alkaloids in Seneclo and Crotalaria

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...

Effect of trypsin inhibitor from Crotalaria pallida

A proteinaceous trypsin inhibitor was purified from Crotalaria pallida seeds by ammonium sulfate precipitation, affinity chromatography on immobilized trypsin–Sepharose and TCA precipitation. The trypsin inhibitor, named CpaTI, had Mr of 32.5 kDa as determined by SDS-PAGE and was composed of two subunits with 27.7 and 5.6 kDa linked by disulfide bridges. CpaTI was stable at 50 °C and lost 40% o...

Comparative Analysis and Nutritional Assessment of Raw Seeds of Crotalaria Species

Five different species of Crotalaria were analysed for their proximate and mineral composition, protein fractions, amino acid profile of total seed proteins, fatty acid profile of seed lipids, in vitro protein digestibility vitamins (niacin and ascorbic acid) and certain anti-nutritional factors. The major findings of the study were as follows: crude protein content ranged from 12.50 27.12%, cr...
