Proximate composition of the seeds and chemical analysis of the oils of Lonchocarpus sericeus and Lonchocarpus cyanescens were determined. The oil content of the seed of L. cyanescens is 29.71 ± 0.20% while that of L. sericeus is 28.00 ± 0.50%. The seeds as well as the oils of L. cyanescens and L. sericeus were found to be rich in K, Na and Fe. Linolenic (C18:3) and oleic (C18:1) acid are the dominant fatty acids while the neutral lipids the dominant lipid class in the oils. Phytol, sterols, beta-tocopherol and hydrocarbons were identified in the unsaponifiable matters of the oils using GC-MS. The HPLC results revealed the presence of glycolipids, which are monogalactosyldiacylglycerol, digalactosyldiacylglycerol, digalactosylmonoacylglycerol and monogalactosylmonoacylglycerol. Molecular speciation of the triacylglycerol revealed the presence of molecular species with equivalent carbon chain numbers C(36) (L. sericeus) and C(50) (L. cyanescens) to be dominantly present in the oils.
测定了长毛野桐和乌桕种子的近缘组成和油的化学分析。L. cyanescens 种子的油含量为 29.71±0.20%，而 L. sericeus 的油含量为 28.00±0.50%。L. cyanescens 和 L. sericeus 的种子和油都富含 K、Na 和 Fe。亚麻酸（C18:3）和油酸（C18:1）是主要的脂肪酸，而中性脂质是油中的主要脂质类。用 GC-MS 在油的不可皂化物中鉴定出植醇、甾醇、β-生育酚和碳氢化合物。HPLC 结果表明存在糖脂，即单半乳糖二酰甘油、双半乳糖二酰甘油、双半乳糖单酰甘油和单半乳糖单酰甘油。三酰甘油的分子分类表明，在油中存在具有相同碳链数 C（36）（L. sericeus）和 C（50）（L. cyanescens）的分子种类占主导地位。
