不同产地宁夏枸杞特征化学成分及营养成分比较

以产自银川芦花台园艺场和中宁县的宁夏枸杞宁杞1号入药果实和叶为评价器官，比较了其特征化学成分和营养成分。结果表明，不同产地的枸杞果实中天门冬氨酸、谷氨酸、丙氨酸、精氨酸和脯氨酸含量较高，枸杞叶中天冬氨酸、谷氨酸、亮氨酸和赖氨酸含量较高。两产地的枸杞果实中各种氨基酸含量各有高低，但差异都不明显；枸杞叶中一些氨基酸含量要高于枸杞果实，如苏氨酸、甘氨酸、缬氨酸、异亮氨酸、亮氨酸、酪氨酸、苯丙氨酸、赖氨酸和色氨酸。甜菜碱含量中宁县枸杞风干果比芦花台枸杞风干果高44.2 %；多糖含量芦花台枸杞风干果和风干叶均略高于中宁县枸杞风干果和风干叶；VC含量芦花台枸杞风干果和风干叶均明显高于中宁县枸杞风干果和风干叶。不同干燥方式下，枸杞冻干果胡萝卜素损失较大，风干果损失较小；而VC含量则是冻干果损失较小，风干果损失较大。

Comparison of Chemical Composition and Nutritional Components of Genuine Traditional Lycium barbarum L.Produced from Different Habitats

It is a comparison about the chemical composition and nutritional components of the fruit and leaf of genuine traditional Lycium barbarum L. ‘Ningqi No.1’produced from Luhuatai Horticultural Farm of Yinchuan and Zhongning County.The results show that the highest amino acids contents are Asp,Glu,Ala,Arg and Pro both in fruits and leaves,but no significant difference was observed between the fruits produced in Luhuatai Horticultural Farm of Yinchuan and Zhongning County.The lycine content of Air-drying fruit produced in Zhongning County was 44.2 % higher than that produced in Luhuatai Horticultural Farm of Yinchuan.The polysaccharide content of air-drying fruit and leaf produced in Luhuatai Horticultural Farm of Yinchuan was higher than that produced in Zhongning County.The VC content of air-drying fruit and leaf produced from Luhuatai Horticultural Farm of Yinchuan was distinctively higher than that produced in Zhongning County.The loss of carotene content of freeze-drying fruit was higher than that of air-drying fruit.While the loss of VC content of air-drying fruit was higher than that of freeze-drying fruit.
