Abstract: 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.
