dc.descriptionThe phytochemical investigation of Solanum crinitum Lam led to the isolation from the fruit trichomes of four flavonoids, tiliroside (1), astragalin (2), kaempferol (3), biochanin A-7-O-β-D-apiofuranosyl-(1→5)-β-D-apiofuranosyl-(1→6)-β-D-glucopyranoside (7), along with 4-hydroxybenzoic acid (12), and four cinnamic acid derivatives, cis- and trans- coumaric acids (10 and 11) and cis- and trans- ethyl coumarate (8 and 9). Three tri-glycosyl-steroidal alkaloids, solamargine (13), 20-epi-solamargine (14) and solasonine (16) were isolated from the methanolic extract of the green fruits. The derivatives 3,5,7,4'-tretra-O-methyl-kaempferol (4), 3,7,4'-tri-O-methyl-kaempferol (5), 3,7,4'-tri-O-methyl-5-O-acetyl-kaempferol (6), the peracetyl-epi-solamargine (15) and peracetyl-solasonine (17) were prepared. The structures were established through the analysis of their spectral data. The complete ¹H and 13C NMR data assignments of the new peracetyl derivatives of the alkaloids were made.
dc.descriptionO estudo fitoquímico de Solanum crinitum Lam forneceu quatro flavonóides: tilirosídeo (1), astragalina (2), kaempferol (3) e biochanina A-7-O-β-D-apiofuranosil-(1→5)-β-D-apiofuranosil-(1→6)-β-D-glucopiranosideo (7), ácido 4-hidroxibenzoico (12), e quatro derivados do ácido cinâmico: cis- e trans- cumárico (10 e 11), cis- e trans- cumarato de etila (8 e 9), isolados de tricomas do fruto. Do extrato metanólico de frutos verdes foram isolados três alcalóides esteroidais glicosilados: solamargina (13), 20-epi-solamargina (14) e solasonina (16). Os derivados 3,5,7,4'-tetra-O-metil-kaempferol (4), 3,7,4'-tri-O-metil-kaempferol (5), 3,7,4'-tri-O-metil-5-O-acetil-kaempferol (6), peracetil-epi-solamargina (15) e peracetil-solasonina (17) foram sintetizados e estão sendo registrados pela primeira vez na literatura. As estruturas foram definidas através de análise de dados espectrométricos.
