土壤无机元素对黄芩无机元素及黄芩苷含量的影响

目的:探讨黄芩土壤无机元素对药材无机元素和黄芩苷含量的影响。方法:测定河北承德黄芩中黄芩苷含量、无机元素含量及黄芩根际土壤中无机元素含量,用SPSS 13.0软件对所得数据进行方差分析和相关分析。结果:黄芩对P有明显富集作用,对Zn和Se也有一定的富集。P,Zn,Se的土壤-黄芩迁移能力显著大于其他元素。黄芩中Se含量与其土壤含量显著正相关。黄芩苷与药材中P显著正相关,与Sr,Se呈显著负相关。结论:本实验所用黄芩样品中无机元素含量普遍偏低,尤以微量无机元素明显。黄芩中多数无机元素含量并不直接受制于相应的土壤含量。黄芩药材中无机元素含量与黄芩苷含量具有相关性趋势。

Effects of Inorganic Elements of Soil on Contents of Inorganic Elements and Baicalin in Scutellaria

Objective: Effects of soil inorganic elements on the content of inorganic elements and baicalin in Scutellaria were examined. Method: The content of baicalin and inorganic elements in medicinal material and inorganic elements in soil were determined, and the data obtained was analysed by SPSS 13.0. Result: Scutellaria accumulated phosphorus, zinc and selenium. The transfer ability of phosphorus, zinc and selenium was more strongly than other elements. Selenium had significantly positive correlation between its soil content and medicinal material content. In medicinal material, Baicalin had significantly positive correlation with phosphorus and negative correlation with zinc and selenium. Conclusion: The content of elements in Scutellaria used this experiment was low, especially microelement. The content of many elements in soil had less effect on their content in medicinal material. The content of baicalin may be affected by the inorganic elements content of medicinal material.
