from the lyophilized hydroalcoholic bark of Dipteryx alata (Leguminosae-Papilionoideae) dissolved in a methanol-water (80:20) mixture through a liquid-liquid partition procedure has been investigated against the neuromuscular blockade of the venom of the snake Bothrops jararacussu. The active CH₂Cl₂ sub-extract has been extensively analyzed for its chemical constituents, resulting in the isolation of four
已经研究了通过液-液分配程序从溶解在甲醇-水 (80:20) 混合物中的 Dipteryx alata (Leguminosae-Papilionoideae) 的冻干水醇树皮制备的四种亚提取物对毒液的神经肌肉阻滞的影响的蛇 Bothrops jararacussu。已对活性 CH₂Cl₂ 子提取物的化学成分进行了广泛分析,从而分离出四种羽扇豆烷型三萜:羽扇豆醇、羽扇豆酮、28-hydroxylup-20(29)-en-3-one、桦木脑、九种异黄酮类化合物: 8-O-甲基维甲素、7-羟基-5,6,4'-三甲氧基异黄酮、黑木香素、7-羟基-8,3',4'-三甲氧基异黄酮、7,3'-二羟基-8,4'-二甲氧基异黄酮、臭香素, 7,8,3'-三羟基-4'-甲氧基异黄酮, 7,8,3'-三羟基-6,4'-二甲氧基异黄酮, 双孢菌素, 一种查耳酮:异甘草素,一种金酮:硫黄素和三种酚类化合物:香草酸
