本实验采用分光光度法测定了核桃隔膜中总黄酮的含量,黄酮总含量为6.259%(62.59mg/g),微量元素的测定采用了火焰原子吸收法,10种微量元素含量分别为Na5.69×102μg/g、K6.95×103μg/g、Ca6.22×102μg/g、Mg6.10×102μg/g、Zn6.10μg/g、Fe1.20×102μg/g、Cu2.03μg/g、Co<0.05μg/g、Ni6.10μg/g、Mn16.27μg/g。总黄酮是最新发现的一种激发脑潜能的物质,它能有效地激发脑活力,对提高青少年智力产生积极作用,并且能有效抑制成人及老年人脑功能衰退。
In this experiment, the content of total flavonoids in the walnut membrane was determined by spectrophotometry. The total flavonoid content was 6.259% (62.59 mg/g). The trace elements were determined by flame atomic absorption spectrometry. The content of ten trace elements was Na5.69. ×102 μg/g, K6.95×103 μg/g, Ca6.22×102 μg/g, Mg6.10×102 μg/g, Zn6.10 μg/g, Fe1.20×102 μg/g, Cu2.03 μg/g, Co <0.05 μg/g, Ni6.10 μg/g, Mn 16.27 μg/g. Total flavonoids is a newly discovered substance that stimulates brain potential, it can effectively stimulate brain activity, have a positive effect on improving adolescents’ intelligence, and can effectively inhibit brain function decline in adults and the elderly.
