摘　　要：目的：探讨广东中山地区异地栽培对苦参生长与氧化苦参碱含量的影响，为苦参在华南地区的推广种植提供依据。方法：2010—2012年连续3年于广东省中山市进行了苦参引种试验，测定苦参的株高、叶面积、根干重、根长等生长指标，HPLC法测定氧化苦参碱含量，采用灰色加权关联度理论和模糊数学中的层次评价法对9项主要生长指标进行综合分析。结果：引种的苦参与其主产区的参考系加权关联度为0．8545，二者的相似程度高；引种一年生苦参根氧化苦参碱含量为13．2784mg／g，两年生含量为16．4779mg／g，与原产地相比，一年生的含量持平，两年生比原产地的低28．67％，但比中国药典规定的含量分别高10．65％和37．32％。结论：引种苦参与主产地苦参相似度高，在广东省中山市有较强的适应性，可以在华南地区推广种植。Objective： To study the effect of transplantation on the growth and oxymatrine content of Sophoraflavescens and provide foundation for popularization and cultivation of Sophora flavescens in South China. Methods： Sophora flavescens which was usually plan- ted in North China and Northwest China was planted in a non-traditional location, Zhongshan city, Guangdong Province in South China to test its adaptability. The growth characters, such as plant height, leaf area, dry weight of root, diameter and length of root and so on were measured from 2010 to 2012. The oxymatrine content of one-year old and two-year old root of Sophora flavescens were determined by HPLC. Nine major growth indexes for one-year old Sophora flavescens were comprehensively analyzed and evaluated by the methods of weighted gray relational and hierarchy evaluation of fuzzy mathematics. Results ： The weighted relevancy of introduced and reference cultivars was 0. 8545. The introduced cuhivar was rather adaptable to the geography environment in Zhongshan. Its quality was very close to the reference cultivars. Oxymatrine content of root of one-year old and two-year old Sophoraflavescens was 13. 2784 mg/g （as much as origin）and 16. 4779 mg/g （less than origin 28.67% ） ,respectively. These were 10. 65% and 37.32% higher than the quality standard which were set up in the Chinese Pharmacopoeia （2010 edition）. Conclusion： Sophora flavescens performs quite well in the newly introducing region. It is suitable to be cultivated and extended in South China.
