目的 研究土壤中无机元素对不同产地黄芩中无机元素和黄芩苷量的影响。方法 测定山西、河北、山东、甘肃4个地区的黄芩中黄芩苷量、无机元素量及土壤中无机元素量，采用SPSS 17.0软件对所得数据进行统计分析。结果 不同产地黄芩中黄芩苷的量顺序依次为河北承德 > 山西运城 > 山东临沂 > 甘肃定西。黄芩中K、Fe、Mg量较高。各地黄芩中无机元素量和土壤中无机元素均成正相关，其中山东临沂所产黄芩和土壤中无机元素相关系数为0.953，呈显著正相关。黄芩苷仅与K、Fe、Mn呈正相关，与Cu、Zn、Mg均呈负相关。结论 土壤中无机元素量的多少对黄芩中无机元素量存在一定影响，且黄芩中无机元素量与黄芩苷量具有一定相关趋势。

Objective To study the effect of inorganic element in soil on the content of inorganic elements and baicalin in Scutellaria baicalensis from different regions. Methods The content of baicalin, inorganic elements, and inorganic elements in the soil in S. baicalensis of four regions (Shanxi, Hebei, Shandong, and Gansu provinces) was determined and analyzed by SPSS 17.0 software. Results The sequence of the content of baicalin in S. baicalensis from different regions was Chengde Hebei > Yuncheng Shanxi > Linyi Shandong > Dingxi Gansu. The content of K, Fe, and Mg were high in S. baicalensis. S. baicalensis from different regions was positively correlated with the inorganic elements in the soil. Among them, the correlation coefficient of the S. baicalensis from Linyi in Shandong province and the inorganic elements in soil was 0.953 which showed positive correlation significantly. Baicalin only positively correlated with K, Fe, and Mn; It negatively correlated with Cu, Zn, and Mg. Conclusion The content of inorganic elements in the soil have a certain influence on the content of inorganic elements in S. baicalensis, and it also has a certain related trend with the content of baicalin.
