野生杏仁种质资源在种子的化学成分和应用方面还没有得到足够的重视。研究了长柄杏仁种子的植物化学成分，并对其营养价值进行了分析。中国和蒙古的本地种)。为了评价样品的营养价值，测定了样品的蛋白质、氨基酸、维生素、矿物质和氧化稳定性等参数。结果表明，该种子富含粗脂肪（49.34g/100g）和粗蛋白质（22.30g/100g）。苦杏仁苷的平均含量为3.55%。种子中氨基酸丰富但不完整。种子油中不饱和脂肪酸含量达97.89%，主要以油酸和亚油酸为主。在种子中检测到五种不同的糖，即果糖、葡萄糖、蔗糖、麦芽糖和乳糖。在矿物组成方面，种子含有10种矿物元素和高浓度的锌、钙和硒。坚果也是维生素E、维生素B3、叶酸、植物甾醇、酚类化合物和类黄酮化合物的极好来源。氧自由基吸收能力（ORAC）值为18.64 +/- 0.2 μ mol TE/g，表明种子是一种良好的抗氧化剂膳食来源。此外，这些发现对营养科学很重要，因为脂肪酸、脂溶性维生素、植物甾醇、类黄酮、酚类化合物和ORAC，特别是，似乎对健康有相当大的影响。
Wild almond germplasm resources have still not received enough attention in the chemical composition and application of seeds. The aim of this study was to evaluate the phytochemical composition and analyze the nutritional value of longstalk almond seeds (Amygdalus pedunculata Pall., a native species of China and Mongolia). In order to evaluate the nutritional value of samples, parameters including the protein, amino acids, vitamins, minerals and the oxidative stability were measured. Results indicated that the seeds were rich in crude fat (49.34g/100g) and crude protein (22.30g/100g). The average content of amygdalin was 3.55%. The amino acids in the seeds were abundant but incomplete. The content of unsaturated fatty acid in the seed oil reached 97.89%, which was mostly comprised of oleic acid and linoleic acid. Five different sugars, namely fructose, glucose, sucrose, maltose, and lactose, were detected in the seeds. With regard to mineral composition, the seeds contained ten mineral elements and high concentrations of Zn, Ca, and Se. The nuts were also an excellent source of vitamin E, vitamin B3, folate, phytosterols, and phenolic and flavonoid compounds. The oxygen radical absorbance capacity (ORAC) values (18.64 +/- 0.2 mu mol TE/g) indicated that the seeds were a good dietary source of antioxidants. In addition, these findings are important for the nutrition sciences, because fatty acids, lipid soluble vitamins, phytosterols, flavonoid, phenolic compounds and ORAC, in particular, seem to have considerable effect on health.
