Fourteen compounds were isolated from Aristolochia giberti. These included a new triterperne, (-)-onocera-8,8'-diol. In addition, 3-hydroxypropanoate, acetate, and formate were detected by NMR techniques, which suggests that they are derivatives from 2-butynedioate, which is not detected by ¹H NMR. GC-MS and chemometric analyses of essential oils from stems and leaves showed great similarity between this cultiv...
From hexane fraction of methanol extract of leaves of Tapirira guianensis (Anacardiaceae) were obtained lupeol, 24-methylenecycloartan-3-ol, phytol, α-amyrin, β-amyrin, sitosterol, sitostenone, glycosyl sitosterol, as well as sitosterol esterified with palmitic and stearic acids. Phytol, α-amyrin and β-amyrin esterified with fatty acids were also identified from same extract. The EtOAc extra...
Este trabalho tem como objectivo a análsie do protagonista em cinco romances de Ignácio de Loyola Brandão. Os romances em estudo são: Babel que a cidade comeu; Zero; Dentes ao Sol; O ganhador e O Anônimo Célebre. Procede-se à caracterização e definição do tipo protagonista presente nestas narrativas, assim como à análise do espaço urbano onde a personagem se move.
From the ethanol extract of the stems of Aristolochia chamissonis, spathulenol, sitosterol, beta-sitosteryl-D-glucoside, kolavelool, 13-epi-2-oxo-kolavelool, trans-N-p-coumaroyltyramine, allantoin, aristolochic acid I, and aristolactam AII were isolated. The structures of aristolactam AII and piperolactam A have been revised by means of spectroscopic methods and chemical derivatizations.
From the stems of Aristolochia gehrtii, the cis-N-feruloyl-3-O-methyldopamine and a hemiacetal derivative of 5-hydroxymethylfurfural were isolated, together with twenty-two known compounds. These compounds include five lignans, three terpenes, six alkaloids (five alkamides), two benzoic acid derivatives, and six phenethyl derivatives. The structures of the isolated compounds were determined by means of spectros...
