Copaifera langsdorfii（Desf.）Kuntze（copaiba）种子大量生产，尚未被鉴定。种子油具有香豆素的特征气味（250.1±6.57mg/g）。通过CG/FID测定油的脂肪酸组成，其中亚油酸45.3%，单不饱和脂肪32.3%，饱和脂肪22.4%。无脂种子的总糖、蛋白质和水分含量分别为75.4%、6.8%和14.8%。梭Langsdorfii木葡聚糖的特性粘数为804 mL/g，平均分子量为7.82× 105 g/mol，Rg为65 nm。多分散度为1.7，表明多糖的多分散家族。它的均匀性、低聚合物污染程度和高特性粘度和分子量，代表了作为增稠剂的良好潜力。香豆素和木葡聚糖是C. Langsdorfii种子表明其在化妆品或制药工业中的应用潜力。
Copaifera langsdorfii (Desf.) Kuntze (copaiba) seeds are abundantly produced and have not yet been characterized. The seed oil presents a characteristic odor of coumarin (250.1±6.57mg/g determined through LC). The fatty acid composition of the oil was determined through CG/FID, being 45.3% linoleic acid, 32.3% monounsaturated, and 22.4% saturated fat. For the lipid-free seeds, the total carbohydrate, protein and moisture were 75.4%, 6.8% and 14.8%, respectively. The C. langsdorfii xyloglucan had an intrinsic viscosity of 804mL/g, and the average molar mass (Mw) was 7.82×105g/mol and Rgof 65nm. The degree of polydispersion was 1.7, indicating the polydisperse family of polysaccharides. Its homogeneity, low degree of polymer contaminants and high intrinsic viscosity and molecular mass, represent good potential as a thickening agent. The presence of coumarin and xyloglucan as major components of C. langsdorfii seeds denotes its potential for use in the cosmetic or pharmaceutical industries.
