摘要
采用分光光度法、高效液相色谱法测定新疆精河、甘肃白银、宁夏南梁、宁夏中宁、宁夏惠农、内蒙古乌拉特前旗先锋镇、宁夏固原、青海柴达木8个产地的枸杞干果中类胡萝卜素、玉米黄素、β-胡萝卜素、玉米黄素双棕榈酸酯的含量。结果表明:利用高效液相色谱法检测枸杞中3种主要类胡萝卜素的含量快捷、方便,可以在20 min内对3种类胡萝卜素定性、定量。青海枸杞的类胡萝卜素、玉米黄素、β-胡萝卜素、玉米黄素双棕榈酸酯含量最高。聚类分析将8个产地的枸杞分成了两大类,中宁、固原、青海的枸杞为一大类,其他产地的枸杞为一大类。
Objective： The content of carotenoids,zeaxanthin,β-carotene,zeaxanthin dipalmitate of Lycium barbarum L.dried fruit in eight areas（Jinghe of Xinjiang,Baiyin of Gansu,Nanliang of Ningxia,Zhongning of Ningxia,Huinong of Ningxia,Wulateqianqi Pioneer Town of Neimeng,Guyuan of Ningxia,Chaidamu of Qinghai） was determined by spectrophotometry and HPLC.Result： The method of HPLC to detect three major carotenoids of Lycium barbarum L.was simple and fast.The three major carotenoids could be qualitatived and quantitatived within 20 min.The content of carotenoids,zeaxanthin,β-carotene,zeaxanthin dipalmitate of Lycium barbarum L.dried fruit in Qinghai was the highest in eight areas.The Lycium barbarum L.in eight areas was divided into two categories by cluster analysis.The Lycium barbarum L.in Zhongning,Guyuan,Qinghai was a category,the other was a category.
