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...
متن کاملAlkaloids 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...
متن کاملFlavonoids 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...
متن کاملStudy of the proteolytic activity of the tropical legume Crotalaria spectabilis.
The characterization of legume proteases contributes to the understanding of the physiology of plants and their interaction with the environment. Thirteen extracts from various parts of Crotalaria spectabilis were made using different extraction systems. The highest protein content was found in seeds, and the most pronounced proteolytic activity was observed in leaf extracts, with an optimal pH...
متن کاملStudy of the Proteolytic Activity of the Tropical Legume Crotalaria spectabilis
Legumes of the genus Crotalaria contain appro ximately 550 species dispersed throughout the world, the great majority well adapted to the tropical climate. Only a limited number occurs in temperate regions. They are annual erect herbs or woody shrubs, originated from India, Africa, and Madagascar, and have been used in the paper and animal feed industry as a source of fi bers and silage, in gre...
