摘要
以国家中药材生产质量管理规范 (GAP)种植及农户常规种植的二年、三年生的三七为原料 ,采用电感耦合等离子体发射光谱法 (ICP -AES)测定了两种不同种植方式 ,不同生长期三七不同部位的重金属元素As、Cu、Cd、Cr、Hg、Pb的含量。结果表明 :As、Hg含量较高 ,Cu、Pb次之 ,Cd、Cr含量在植株中未检出。为三七GAP栽培标准和特征制订、三七道地药材的化学特征———化学指纹图谱的建立研究提供理论依据。
Experiments have been done with GAP planted and regular planted twoor three-year-growth Wenshan Gingseng as materials and with ICP-AES method to test the content and the influence of heavy metal elements on different parts of Wenshan Gingseng at different stages. Among the heavy metal elements are As, Cu, Cd, Cr, Hg and Pb. The results of the experiments show that the content of As and Hg is high and that of Cu and Pb is lower. The content of Cd and Cr has not been found in the stem. This will provide the convincing evidences for the making of GAP Wenshan Gingseng planting standards, the character confirmation and the chemical diagram of typical local Wenshan Gingseng.
