1、不同产地枸杞果和叶中总生物碱和总黄酮含量的测定摘要：检测不同地区枸杞果和叶中总生物碱和总黄酮含量，比较各地区含量之间是否存在差异。在对不同地区的枸杞果和叶进行测量时，采用TU-1901型双光束紫外可见分光光度法进行含量的测定，应用滴定法进行枸杞总糖含量测定。甘肃与新疆、青海、宁夏和内蒙古枸杞果中总生物碱含量存在显著差异；新疆与青海、宁夏枸杞果实中总生物碱含量存在显著差异；青海和宁夏枸杞果实中总生物碱含量无显著差异；青海与内蒙枸杞果实中总生物碱含量有显著差异；甘肃和湖北果实中总生物碱含量无显著差异；新疆与湖北果实中总生物碱含量无显著差异。新疆与甘肃枸杞叶总生物碱含量有显著差异；甘肃与宁夏

2、无显著差异；甘肃与内蒙有显著差异；青海与湖北五显著差异；宁夏与湖北有显著差异。新疆与青海、宁夏枸杞果中总黄酮含量无极显著差异，而与甘肃、内蒙和湖北达极显著差异；甘肃与内蒙达极显著差异；内蒙与湖北达极显著差异。新疆与甘肃、宁夏枸杞叶中总黄酮含量无极显著差异，而与青海达极显著差异；青海与内蒙达极显著差异；内蒙与湖北达极显著差异。关键词：枸杞，不同地区，总生物碱，总黄酮GOJIBERRIESANDLEAVESINDIFFERENTREGINESWITHTHEDETERMINATIONOFTOTALALKALOIDSANDFLAVONOIDSCONTENTwangwei(NingxiaUniv
