Blue honeysuckle seeds are often overlooked by the processing industry, but they are a good source of healthy oil. The composition, volatiles, and antioxidant capacity of blue honeysuckle seeds and seed oil were investigated for the first time. The fatty acid profile of the seed oil was analysed using GC-MS. The seed oil was particularly rich in polyunsaturated fatty acid, especially linoleic acid (71.24 ± 1.64 %). HS-SPME-GC-MS analysis temporarily detected 34 and 37 volatiles in the seeds and seed oil, respectively. Notably, aldehydes were identified as the major contributors to the aroma. The phytosterols, tocopherols, and triglycerides were identified in the seed oil. Interestingly, the total phenolic content and antioxidant capacity of the seeds were found to be much higher than the seed oil. This study evaluates the nutritional profile and value of blue honeysuckle seed oil, and suggests that it can be used as new functional oil.
蓝金银花种子常被加工行业忽视，但它们是健康油脂的良好来源。首次对蓝金银花种子及其籽油的成分、挥发性成分和抗氧化能力进行了研究。采用气相色谱-质谱联用仪（GC-MS）分析了籽油的脂肪酸组成。该籽油富含多不饱和脂肪酸，尤其是亚油酸（71.24±1.64%）。顶空固相微萃取-气相色谱-质谱联用（HS-SPME-GC-MS）分析分别在种子和籽油中临时检测到34种和37种挥发性成分。值得注意的是，醛类被确定为香气的主要成分。在籽油中鉴定出了植物甾醇、生育酚和甘油三酯。有趣的是，发现种子的总酚含量和抗氧化能力远高于籽油。本研究评估了蓝金银花籽油的营养成分和价值，并表明其可作为新型功能油使用。
