马铃薯中龙葵素的定性定量分析 摘 要：本试验采取乙醇乙酸法提取不同储藏条件下马铃薯中的龙葵素，用高效液相色谱法对其进行定性定量分析，研究了光照、储藏温度对马铃薯中龙葵素含量的影响。结果表明，马铃薯中的龙葵素含量与温度呈正相关，光照条件对龙葵素含量的影响显著。所以食用马铃 ... p摘nbsp; 要：本试验采取乙醇mdash;乙酸法提取不同储藏条件下马铃薯中的龙葵素，用高效液相色谱法对其进行定性定量分析，研究了光照、储藏温度对马铃薯中龙葵素含量的影响。结果表明，马铃薯中的龙葵素含量与温度呈正相关，光照条件对龙葵素含量的影响显著。所以食用马铃薯应低温避光储存，药用开发马铃薯则应适当提高储藏温度和光照条件。br / 关键词：马铃薯；温度；光照；提取；龙葵素；高效液相色谱br / br / The Qualitative and Quantitative Analysis of the Solanine in Potatobr / Abstract：This experiment uses Ethanol-acetic acid extract solanine in potato on the different storage condition. Using HPLC for qualitatively and quantitatively analyzed of potato.The effects of lighting, storage temperature on the solanie content of potato were investigated by the determination of content and purity. The result showed that the solanie content of potato was positive-correlated with storage temperature. The effect of lighting on the solanine content is remarkable.So should storage potato in low temperature and avoid light conditions. p class=Cfd171/p br / Key words：potato; temperature; light; extract; solanine; HPLC span class=Cfd171/span /p pbr / 目nbsp;nbsp;nbsp; 录nbsp;nbsp;nbsp; 6800字br / 摘nbsp; 要nbsp;nbsp;nbsp; 1br / 关键词nbsp;nbsp;nbsp; 1br / 1前言nbsp;nbsp;nbsp; 1br / nbsp;nbsp;nbsp; 1.1研究不同储藏条件下马铃薯中龙葵素含量的意义nbsp;nbsp;nbsp; 1br / nbsp;nbsp;nbsp; 1.2双溶剂法提取龙葵素nbsp;nbsp;nbsp; 4br / nbsp;nbsp;nbsp; 1.3马铃薯中龙葵素的测定方法nbsp;nbsp;nbsp; 4br / 2实验部分nbsp;nbsp;nbsp; 5br / nbsp;nbsp;nbsp; 2.1实验材料与仪器nbsp;nbsp;nbsp; 5br / nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp; 2.1.1实验材料（包括药品、试剂、材料）nbsp;nbsp;nbsp; 5br / nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp; 2.1.2实验仪器nbsp;nbsp;nbsp; 6br / nbsp;nbsp;nbsp; 2.2实验原理与方法nbsp;nbsp;nbsp; 6br / nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp; 2.2.1实验原理nbsp;nbsp;nbsp; 6 span class=Cfd171/span br / nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp; 2.2.2实验方法nbsp;nbsp;nbsp; 6br / nbsp;nbsp;nbsp; 2.3龙葵素标准溶液的配置nbsp;nbsp;nbsp; 7br / nbsp;nbsp;nbsp; 2.4色谱条件nbsp;nbsp;nbsp; 7br / nbsp;nbsp;nbsp; 2.5标准曲线的绘制nbsp;nbsp;nbsp; 7br / nbsp;nbsp;nbsp; 2.6龙葵素样品的处理nbsp;nbsp;nbsp; 7br /
