摘要
目的 考察不同产地和植株年龄对苦参干燥根中氧化苦参碱含量的影响 ,为选择合适的大规模人工种植场地、合理的管理及物种保护提供可考的依据。方法 采用 HPL C法测定苦参干燥根中氧化苦参碱的含量并采用SPSS 9.0及 Microsoft Excel软件进行数据统计和分析。结果 从 17个省、自治区采集的苦参根样品中氧化苦参碱的含量差异很大 (0 .4 94 %～ 4 .12 7% ) ,其中以黑龙江省采集的样品中氧化苦参碱的平均含量最高 (3.4 93% )。方差分析表明采自北方寒冷干燥的高纬度地区的样品中氧化苦碱的含量明显高于采自南方温暖潮湿的低纬度地区的样品。而且 ,植株年龄与苦参干燥根中氧化苦参碱含量呈相关。结论 不同产地和植株年龄均会明显影响苦参根中氧化苦参碱的含量 ;生长在寒冷干燥的高纬度地区的苦参根中氧化苦参碱含量较高。
Object The influence of producing area and plant age on oxymatrine levels in the dried root of Sophora flavescens Ait. has been investigated to provide useful information to optimize the areas for mass scale propagation, proper management and species conservation. Methods The oxymatrine was quantified by HPLC and various statistical treatments were carried out following SPSS 9.0 and Microsoft Excel. Results The oxymatrine concentrations in the root samples collected from 17 provinces and regions differed from 0.494% to 4.127% and the maximum oxymatrine content (3.493%) was recorded in the root sample collected from Heilongjiang Province. Analysis of variance indicates a highly significant difference in the oxymatrine content of roots collected from different provinces, and the samples from the cold arid northern high-latitude areas had higher oxymatrine than those from warm humid southern low-latitude areas in the China's Mainland. Plant age is positively related to the total root biomass and oxymatrine content. Conclusion The oxymatrine content in the roots of S. flavescens is quite different between different areas and plant ages. The S. flavescens growing in the cold arid northern high-latitude areas had higher oxymatrine concentration.
