Sesquiterpenos de sementes de Guarea guidonia (Meliaceae)

Abstract: Recebido em 28/3/11; aceito em 1/7/11; publicado na web em 19/8/11SESQUITERPENES FROM THE SEEDS OF Guarea guidonia (MELIACEAE). Two new sesquiterpenes 6α-ethoxyeudesm-4(15)-en-1β-ol (1) and (7R*)-5-epi-opposit-4(15)-ene-1β,7-diol (7) were isolated from the seeds of a specimen of Guarea guidonia (Meliaceae). Five other known sesquiterpenes, eudesm-4(15)-ene-1β,6α-diol (2), 5-epi-eudesm-4(15)-ene-1β,6β-diol (3), eudesm-4(15)-ene-1β,5α-diol (4), eudesm-4(15),7-dien-1β-ol (5) and (7R*)-opposit-4(15)-ene-1β,7-diol … Show more

“…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).…”

“…Interestingly, both enantiomers were reported from plants, such as Croton caudatus var. tomentosus, 19 Guarea guidonia (Meliaceae), 20 Caragana intermedi, 21 Eupatorium fortune, 22 and Litsea verticillata. 23 Recently, (+)-10αeudesm-4(15)-ene-1α,6α-diol was prepared in total synthesis.…”
