摘要：为获得优质马铃薯品种，实现品种结构优化，并改变目前切块播种的培育方法，解决种薯繁殖高成本低速度的瓶颈问题，本研究通过对10多个马铃薯品种的干率、蛋白质含量、淀粉含量、褐变、多酚氧化酶(PPO)活性及矿物质的评价和鉴定，筛选出综合性状好的品种。实验结果表明，从这些材料中筛选出来的“紫薯一号”符合当前高色素育种方向的优质特异品种。并通过以该品种块茎为材料，研究了对马铃薯黄酮的提取因素来获得其最适条件，使马铃薯黄酮得到充分的开发和利用，减少种薯用量，降低种薯成本，增加了马铃薯的食用价值。该研究为开发马铃薯在生产、食疗、临床等方面提供技术指导。

Potato Physical And Chemical Quality Of The Research And Its Flavonoids Extraction And The Determination
Abstract: This article included the protein content, the starch content, the turning brown, the polyphenoloxidase (PPO) activeness and the mineral substance appraisal and the appraisal to more than 10 potato varieties. The synthesis character was screened in order to obtain high quality potato species. The result of this study showed that No.1 purple potato was the high quality species. And through take the block stem as the material, studied has obtained its suitable conditions for the potato flavanone extraction. The aim was to full use the potato flavanone, reduce the seed amounts and to increase potato's edible value. This research can provide the technical guidance for the potato production, clinical trial of the potato flavanone.
