不同栽培居群板蓝根抗内毒素活性差异原因的研究

目的：探讨不同栽培居群板蓝根抗内毒素活性差异形成的原因。方法：采集了板蓝根药材１９份，将１２份种子在上海进行了异地栽培，又将四倍体种子栽培于５个有代表性的产地，通过抗内毒素实验对药材样品进行比较。结果：采集的１９份样品活性差异十分明显，异地栽培后的１２份样品差异并未消失，四倍体板蓝根在５个产地栽培后活性基本持平。结论：在影响板蓝根抗内毒素活性的诸多因素中，种质是首要的，环境相对次之。

Research on Cause of Distinction in AntiendotoxicActivation of Radix Isatidis from Different Cultivated Populations

Objective: To research into the cause of distinction in antiendotoxic activation of Radix Isatidis from different cultivated populations. Method: 19 samples of Radix Isatidis were gathered.12 portions of seeds were cultivated in the same field in Shanghai,and the selected and artificially bred autotetraploid seeds were planted in 5 different locations.All the samples were compared through antiendotoxic experiment.HZResults: There are some marked distinction among the 19 samples from different populations.The distinction of the 12 samples cultivated in the same field didn't disappear.The activation of autotetraploid from 5 different locations didn't vary on the whole. Conclusion: Germplasm is the main factor to cause activation distinctions of Radix Isatidis,while environment is less important.
