Nunomura, Rita de Cássia Saraiva; Pinto, Ângelo da Cunha; Nunomura, Sergio Massayoshi; Pohlit, Adrian Martin; Amaral, Aná Cláudia FernandesSimaba guianensis subesp. ecaudata (Simaroubaceae) is a tree found in the Brazilian Amazon. This work describes for the first time the fractionation of stems of this species that resulted in the isolation of the cytotoxic triterpene piscidinol A, the alkaloid 9-methoxycanthin-6-one, caryophyllene oxide, also isolated for the first time from this species and a new alkaloid (6-methoxy-(9H-β-carbolin-1-il)-(Z)-2-p...
Triterpenes and a canthinone aekaloid from the stems of Simaba polyphylla (cava...
Saraiva, Rita de Cássia Guedes; Pinto, Ângelo da Cunha; Nunomura, Sergio Massayoshi; Pohlit, Adrian MartinSimaba polyphylla is a small tree found in the Amazon region, known by the common names "marupazinho" or "serve para tudo". It is used in traditional medicine for the treatment of fevers. This work describes the phytochemical study of the hexane extract and chloroform fraction obtained by partitioning the methanol extract of stems, which led to isolation and identification of the triterpenes niloticin, dyhidron...
