山东同一种植基地不同形态瓜蒌的种子蛋白研究

目的：研究山东同一种植基地不同形态瓜蒌种子中的蛋白质。方法：采用紫外分析法测定蛋白质的含量，利用聚丙烯酰胺凝胶电泳技术进行蛋白电泳分析，采用Biosens Gel Imaging System软件绘制指纹图谱。利用NTSYS-pc软件进行聚类分析，计算遗传相似系数。结果：不同样品的蛋白质含量具有明显差异，蛋白电泳图谱具有多条共有带。结论：种子蛋白质的含量不是评价瓜蒌质量优劣的主要指标，蛋白电泳图谱的共有条带可作为鉴定瓜蒌真伪的重要依据。

Study on Seed Protein of Trichosanthis Fructus from Same Planting Base in Shandong Province

This study was aimed to investigate the seed protein of different forms of Trichosanthis fructus from Shandong province. UV analyzer was used to analyze the seed protein content. PAGE fingerprint was drawn by Biosens Gel Imaging System software. The Jaccard coefficient was worked out by using NTSYS-pc software. A cluster dendrogram of different samples was established based on unweighted pair-group method with arithmetic means (UPGMA). The results showed that the content of different samples was obviously different. But there were many common bands in the fingerprints of PAGE. It was concluded that the content of seed protein cannot be used as the main index to evaluate the quality of Trichosanthis fructus. The common bands in fingerprints of PAGE can be used to identify Trichosanthis fructus.
