Pyrrolizidine Alkaloids from Heliotropium

چکیده
Investigation of the pyrrolizidine alkaloids of Heliotropium arbainense resulted in the isolation and identification of heliotrine, europine and 7-angelylheliotrine. From H. ovalifolium three alkaloids were isolated: supinine, 7-angelylheliotridine and an alkaloid which was shown to be of the heliotridine monoester type with a dehydrated viridifloric acid.

Pyrrolizidine alkaloids from Heliotropium transoxanum Bunge
Background and objectives: The plants belonging to the genus Heliotropium L. (Boraginaceae) are the main sources of toxic pyrrolizidine alkaloids (PAs). In the present study, we have investigated the PAs of the aerial parts of Heliotropium transoxanum Bunge, a perennial species native to Iran. Methods: Silica gel column chromatography and silica gel PTLC were applied ...

Islet cell tumors of the pancreas found in rats given pyrrolizidine alkaloids from Amsinckia intermedia Fisch and Mey and from Heliotropium supinum L.
One adenoma and one adenocarcinoma of the islet cells and one adenoma of the exocrine pancreas were found in 3 out of 15 rats given a single dose (500 to 1500 mg/kg body weight) of pyrrolizidine alkaloids from Amsinckia intermedia Fisch and Mey (Boraginaceae), tarweed, a plant known to cause livestock losses from liver damage in the United States. Among rats treated with Heliotropium supinum L....
متن کاملPyrrolizidine Alkaloids from Heliotropium indicum
Um novo alcalóide denominado Helindicina (1), e o conhecido licopsamina (2) foram isolados das raízes de Heliotropium indicum (Boraginaceae). As estruturas foram estabelecidas tendo como base um amplo estudo de 1D e 2D RMN (COSY, HMBC, HMQC, NOESY) e HREIMS. Este representa o primeiro relato de um alcalóide contendo um anel lacônico no gênero Heliotropium. Estes alcalóides mostraram moderada at...
متن کاملOrnithine decarboxylase, polyamines, and pyrrolizidine alkaloids in senecio 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...
