中文摘要：
目的：比较宁夏不同产地野生及种植甘草中总黄酮含量。方法：采用紫外分光光度法测定总黄酮含量,对宁夏各产地野生与种植甘草中总黄酮含量进行比较分析。结果：甘草黄酮在4.36～43.6 mg.L-1成良好的线性关系,回归方程为Y=0.013X＋0.054（R=0.999 2）;宁夏不同产地甘草中总黄酮含量差异较大,同一产地野生甘草的总黄酮含量大于种植品,旱地种植甘草中总黄酮含量高于水地种植品。结论：环境综合机制对甘草中总黄酮含量的影响明显,该研究为宁夏甘草的可持续利用与研究提供参考。
英文摘要：
Objective：The essay aims at making a comparative study on the total flavonoids content of several kinds of wild and cultivated Glycyrrhiza uralensis in different producing regions in Ningxia.Method： The content of total flavonoids was determined by UV.The total flavonoids of wild and cultivated G.uralensis in different producing regions in Ningxia were exmined and analyzed.Result： The determination method had good linear relationship in the ranges of 4.36-43.6 mg · L-1 for total flavonoids.As for the total flavonoids of wild G.uralensis in different producing regions,there is a remarkable differert in total flavonoids.The content of total flavonoids in wild was higher than that in cultivated in same producing regions,and the content in cultivated in dry land was higher than that in cultivated in irrigated land.Conclusion： It was important that the regional features influenced on the total flavonoids content of G.uralensis.
