Estudo em raiz e ráquis foliar de spathelia excelsa: fitoquímica e atividade frente ao fungo Moniliophthora perniciosa associado ao cupuaçuzeiro (Theobroma grandiflorum)

Abstract: (2), alkaloids folinin and casimiroin mixture (3a,b), plus a further casimiroin (3b) were identified in methanol extract from root. The CH 2 Cl 2 extract from the rachis yielded protolimonoid 3β-angeloyl-21,24-epoxy-7α,21α,23α,25-tetrahydroxy-4α,4β,8β,10β-tetramethyl-25-dimethyl-14,18-cyclo-5α,13α,14α,17α-cholestane (4), and methanol extract, the limonoids limonin diosphenol (5) and perforatin (6), as well as the chromone biflorin (7). Harrisonin and biflorin were isolated for the first time in this genus. On … Show more
