本文主要对南梁、惠农、固原、中宁、内蒙、甘肃、青海、新疆八个产地的枸杞干果理化成分的差异显著性做了研究，从而综合比较了八个产地枸杞品质的差异。分别测定了其7种理化成分和3种活性成分，并做了方差分析、显著性分析（LSD）、加权得分和聚类分析。结果表明，各产地枸杞综合加权得分分值大小及品质高低顺序依次为：中宁7.3>南梁5.1>新疆4.8>惠农4.5>甘肃3.8>青海3.7>内蒙3.6>固原3.2；银川南梁和惠农的枸杞品质与中宁的枸杞非常接近，故优质枸杞中心仍然在宁夏，但是地点已呈现由中宁往南梁、惠农等地转移的趋势。

This paper mainly reported the differences of physical and chemical composition of Lycium barbarum L. dried fruit in eight areas ( Nanliang, Huinong, Guyuan, Zhongning, Inner Mongolia, Gansu, Qinghai and Xinjiang), thus to compare the quality differences of Lycium barbarum L. in different producing areas. Seven kinds of physical and chemical composition and three kinds of active ingredient were determined. Also variance, significant analysis, weighted scoring and clustering analysis of the results were made. The results showed that the comprehensive weighted score and the order of comprehensive quality of Lycium barbarum L. in different areas as follows, Zhongning 7.3>Nanliang 5.1>Xinjiang 4.8>Huinong 4.5>Gansu 3.8>Qinghai 3.7>Inner Mongolia 3.6>Guyuan 3.2. The qualities of Lycium barbarum L. in NanLiang and HuiNong are very close to Zhongning’s. It was determined that the center of superior Lycium barbarum L. was in Ningxia, but the place has transferred to Nanliang and Huinong from Zhongning.
