oleanolic acid, canthic acid, 2-(4-hydroxyphenyl)ethyl triacontanoate, newbouldiamide, 5,7-dihydroxydehydroiso-alpha-lapachone, beta-sitosterol, and beta-sitosterol glucopyranoside. The structure elucidation of the isolated compounds was established based on spectroscopic studies, notably of the 2D NMR spectra. The antimalarial activity of compound (1) against Plasmodium falciparum in vitro shows moderate
对 Newbouldia laevis (Bignoniaceae) 根部化学成分的研究已经分离和表征了一种名为 newbouldiaquinone A (1) 的萘醌-蒽醌偶联色素以及 14 种已知化合物:芹菜素、金黄酮、newbouldiaquinone、lapachol, 2 -甲基蒽醌、2-乙酰基呋喃-1,4-萘醌、2,3-二甲氧基-1,4-苯醌、齐墩果酸、莨菪酸、2-(4-羟基苯基)乙基三十酸、新博二酰胺、5,7-二羟基脱氢异α -拉帕酮、β-谷甾醇和β-谷甾醇吡喃葡萄糖苷。分离化合物的结构解析是基于光谱研究,特别是 2D NMR 光谱。化合物(1)在体外对恶性疟原虫的抗疟活性显示出对寄生虫生长的适度化学抑制。
