用高效凝胶蛋白往分离豆薯种子蛋白租提液，结合光电二极管阵列检测器对分离的蛋白峰进行紫外光谱扫描来确认蛋白的纯度，测定了3种蛋白的分子量，采用邻苯二甲醛（OPA）柱后衍生法测定了豆薯种子蛋白的氨基酸含量。
High-performance gel protein was used to separate the leached liquid of potato seed protein and the photodetector diode array detector. The purity of the protein was confirmed by UV spectral scanning. The molecular weights of the three proteins were determined by using phthalaldehyde OPA) column post-derivatization method to determine the amino acid content of the yam seed protein.
