Pyrrolizidine 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 in human diet.
Pyrrolizidine alkaloids are the leading plant toxins associated with disease in humans and animals. Upon ingestion, metabolic activation in liver converts the parent compounds into highly reactive electrophiles capable of reacting with cellular macromolecules forming adducts which may initiate acute or chronic toxicity. The pyrrolizidine alkaloids present a serious health risk to human populati...
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 کاملEvaporative light scattering detection of pyrrolizidine alkaloids.
A reverse-phase high-performance liquid chromatography method utilizing evaporative light scattering detection (ELSD) has been developed for the simultaneous detection of hepatotoxic pyrrolizidine alkaloids with and without chromophores, namely, riddelliine, riddelliine N-oxide, senecionine, senecionine N-oxide, seneciphylline, retrorsine, integerrimine, lasiocarpine and heliotrine. Pyrrolizidi...
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 ...
