研究了黄麻（Corchoruscapsularis）纤维的亲脂性抽出物的化学组成。提取物含量较低（0.4%），用气相色谱-质谱联用仪分析了其组成。为了更好地表征少量存在的不同同源系列和硬币，还通过固相萃取对提取物进行分级。黄麻纤维中最主要的亲脂性化合物是高分子量酯蜡（占总提取物的24%），其次是游离脂肪酸（17%）、游离脂肪醇（17%）和α-羟基脂肪酸（14%）。此外，还鉴别出大量烷烃（6%）、ω-羟基脂肪酸（6%）、甾醇（6%）、甾体和三萜酮（3%）和甾醇糖苷（1%），以及少量甘油单酯和甘油二酯。(C)2009 Elsevier B. V.保留所有权利。
The chemical composition of the lipophilic extractives from jute (Corchorus capsularis) fibers, which are used for high-quality paper pulp manufacturing, was thoroughly studied. The extractives content was low (0.4%), and its composition was studied by gas chromatography-mass spectrometry. For a better characterization of the different homologous series and coin pounds present in minor amounts, the extract was also fractionated by solid-phase extraction. The most predominant lipophilic compounds present in jute fibers were high molecular weight ester waxes (24% of total extract), followed by free fatty acids (17%), free fatty alcohols (17%)and alpha-hydroxyfatty acids(14%). Additionally, significant amounts of alkanes(6%), omega-hydroxyfatty acids (6%), sterols (6%), steroid and triterpenoid ketones (3%) and steryl glycosides (1%) were also identified, together with minor amounts of rnono- and diglycerides.
