从苦楝茎皮中提取分离并鉴定了 5个微量酚性化合物。它们的结构分别为阿魏酸二十六醇酯(Ⅰ)、阿魏酸二十四醇酯(Ⅱ)、阿魏酸二十五醇酯(Ⅲ)、阿魏酸二十七醇酯(Ⅳ)、阿魏酸二十八醇酯(Ⅴ)。均为从苦楝中首次分离得到。

Five minor ferulic acid esters (Ⅰ～Ⅴ) were identified in a petrol extract of Melia azedarach stem bark, one (Ⅰ) of which was isolated with no impurity for the first time By chemical and spectral methods, their structures were elucidated as hexacosylferulate (Ⅰ); tetracosylferulate (Ⅱ); pentacosylferulate (Ⅲ); heptacosylferulate (Ⅳ) and octacosylferulate (Ⅴ), respectively.
