Phytochemical investigation from carnauba (Copernicia prunifera) wax led to the identification of sixteen dammarane-type triterpenes, including thirteen new characterized as: (24R*)-methyldammara-20,25-dien-3α-ol and a mixture of alkyl (24R*)-methyldammar-25-en-20-ol-3β-carboxylates, together with three previously described triterpenes: carnaubadiol, (24R*)-methyldammara-20,25-dien-3β-ol and (24R*)
巴西棕榈蜡的植物化学研究导致鉴定出十六种丹玛兰型三萜,其中包括十三种新特征为:(24R *)-甲基达玛拉-20,25-dien-3α-ol和烷基混合物(24R * )-甲基dammar-25-en-20-ol-3β-羧酸盐以及三种先前描述的三萜烯:巴西二醇,(24R *)-甲基达玛拉-20,25-dien-3β-ol和(24R *)-24-甲基达玛拉-20,25-dien-3-one。此外,还获得了四种脂肪醇(二十二烷醇,二十二烷醇,十四烷醇和十六烷醇)以及四种固醇(胆固醇,菜油甾醇,豆甾醇和谷甾醇)。使用经典色谱方法分离这些化合物,并通过光谱和化学方法确定其结构。
