“…In Brazil, there are six genera and about 100 species (Lorenzi and Matos, 2008). The members of this family have a wide diversity of chemical compounds, including limonoids, triterpenes, steroids, diterpenes, sesquiterpenes and coumarins (Cortez et al, 2000;Lago et al, 2000Lago et al, , 2002Soares et al, 2012;Scur et al, 2016). Limonoids are the most abundant compounds and, probably, the largest representatives of the class of terpenes with insecticidal activity (Luo et al, 1999).…”

“…Na medicina popular é utilizada no tratamento de reumatismo, hidropsia e tumores artríticos, tendo, ainda, propriedades adstringentes, purgativas, febrífugas, abortivas, eméticas e anti-inflamatórias. 1 Estudos fitoquímicos prévios dos extratos hexânico e etanólico da casca do tronco desta espécie, além do óleo volátil de suas folhas, resultaram no isolamento de limonoides, 2-3 esteroides, 4 seco-esteroides, 5 cumarinas, 2 di-, 4,6,7 tri-4 e sesquiterpenos. 2,4,8 O presente trabalho trata do estudo fitoquímico de sementes de um espécime de G. guidonia, que levou ao isolamento de sete sesquiterpenos, sendo dois deles inéditos: 6α-etoxieudesm-4(15)-eno-1β-ol (1), eudesm-4(15)-eno-1β,6α-diol (2), 5-epi-eudesm-4(15)-eno-1β,6β-diol (3), eudesm-4(15)-eno-1β,5α-diol (4), eudesm-4(15),7-dien-1β-ol (5), (7R*)-oposit-4(15)-eno-1β,7-diol (6) e (7R*)-5-epioposit-4(15)-eno-1β,7-diol (7) (Figura 1).…”
