The content of nine mineral elements in the root, stem and leaf of 1-3 years old Scutellaria baicalensis, skullcap tea, and its solution was determined by the inductively coupled plasma atomic emission spectrometry (ICP-AES). The results show that the main mineral elements in the root, stem and leaf are similar. The main mineral elements include K, Ca, Mg, P, Al and Fe. The content ratio of Zn, Mn, Cu, Fe, Al, P, Mg, Ca and K in the leaf of Scutellaria haicalensis is 1 : 3 : 6 : 15 : 18 19 : 41 : 333 : 423. The contents of Fe, Mn, P, Mg and Ca in the stems and leaves of Scutellaria baicalensis increase with the increase of cultivation period. There were K, Ca, Mg and other mineral elements in the skullcap tea, and Fe, Zn and Mg were easy to be dissolved, the dissolution rates were 61.8%, 55.4% and 61.4% respectively. This study can provide scientific basis for rational utilization of the above ground resources of Scutellaria baicalensis.
采用电感耦合等离子体原子发射光谱法（ICP-AES）测定了1-3年生黄芩的根、茎、叶、黄芩茶及其溶液中9种矿质元素的含量。结果表明，根、茎、叶中的主要矿质元素相似。主要矿质元素包括钾、钙、镁、磷、铝和铁。黄芩叶中锌、锰、铜、铁、铝、磷、镁、钙和钾的含量比为1:3:6:15:18:19:41:333:423。黄芩茎和叶中铁、锰、磷、镁和钙的含量随栽培年限的增加而增加。黄芩茶中含有钾、钙、镁等矿质元素，铁、锌和镁易于溶解，溶解率分别为61.8%。55.4%和61.4%。本研究可为合理利用黄芩地上资源提供科学依据。
