Oil content and bioactive properties of almond and walnut kernels were investigated in developing almond and walnut kernels at 10 days intervals. The oil contents of almond and walnuts after the first harvest (1.H) stage changed between 46.2% and 55.0% to 39.1% and 70.5%, respectively (p<0.05). Oleic acid contents of almond and walnut oils ranged from 71.98% (1.H) to 78.68% (5.H) and 10.51% (1.H) to 16.78% (2.H) depending on harvest (H) times, respectively (p<0.05). In addition, linolenic acid contents of walnut and almond oils were found between 62.35% and 67.78%, and 12.02% and 17.65%, respectively. The almond kernel oil after the first harvest stage contained 1.045, 1.058, 1.018, 0.995 and 0.819 mg/kg ɑ-tocopherol, respectively. γ-Tocopherol contents of walnut oil changed between 1.364 (3.H) and 2.954 mg/kg (1.H). The β-sitosterol contents of both almond and walnut oils were found between 1956.6 (5.H) and 2557.7 (1.H), and 1192.1 (3.H) and 4426.4 mg/kg (1.H). The study exhibited the presence of high percentage of oleic and linoleic for almond and walnut, respectively, and γ-tocopherol and β-sitosterol.
每隔10天对发育中的杏仁和核桃仁的含油量及生物活性特性进行研究。首次收获（1.H）阶段后，杏仁和核桃的含油量分别从46.2%至55.0%变为39.1%至70.5%（p<0.05）。杏仁油和核桃油中油酸含量分别根据收获（H）次数在71.98%（1.H）至78.68%（5.H）和10.51%（1.H）至16.78%（2.H）之间变化（p<0.05）。此外，核桃油和杏仁油中亚麻酸含量分别在62.35%至67.78%和12.02%至17.65%之间。首次收获阶段后的杏仁核油中α-生育酚含量分别为1.045、1.058、1.018、0.995和0.819毫克/千克。核桃油中γ-生育酚含量在1.364（3.H）至2.954毫克/千克（1.H）之间变化。杏仁油和核桃油中β-谷甾醇含量分别在1956.6（5.H）至2557.7（1.H）和1192.1（3.H）至4426.4毫克/千克（1.H）之间。该研究表明杏仁和核桃分别含有高比例的油酸和亚油酸，以及γ-生育酚和β-谷甾醇。
