Pyrrolizidine 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 کاملAntimicrobial activity of 2,5-dihydroxy-3-methyl-1,4-benzoquinone from Embelia schimperi.
Chromatographic separation of an ethyl acetate extract from Embelia schimperi led to the isolation of a new compound identified as 2,5-dihydroxy-3-methyl-1,4-benzoquinone (1) on the basis of spectroscopic and physical data. The plant's crude extract and pure compound 1 were assayed for in vitro antimicrobial activity against clinical strains of Salmonella spp., Proteus spp., Pseudomonas aerugin...
متن کاملPolymeric complexes of 2,5-Dihydroxy-1,4-benzoquinone with some Lanthanides
Polymeric solid complexes having distorted square antiprismatic geometries of La(III), Ce(III), Pr(III), Nd(III), Sm(III), Gd(III) and Dy(III) with 2,5-Dihydroxy-1,4benzoquinone are reported. Their compositions and geometries are supported by elemental analysis, IR spectroscopy, magnetic susceptibility measurements and electronic absorption spectroscopic studies.
