متن کاملPyrrolizidine Alkaloids from Heliotropium
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.
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 کاملPyrrolizidine 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 ...
