摘要
采用电感耦合等离子体原子发射光谱法测定了1年～3年生黄芩根、茎、叶、茶、茶水中九种矿质元素的含量,结果表明,黄芩根、茎、叶中富含K,Ca,Mg,P,Al,Fe等矿质元素,黄芩叶中Zn,Mn,Cu,Fe,Al,P,Mg,Ca,K的含量比例为1∶3∶6∶15∶18∶19∶41∶333∶423;黄芩茎叶内Fe,Mn,P,Mg,Ca等矿质元素的含量有随栽培年限的增加而升高的趋势;黄芩嫩叶茶中主要含K,Ca,Mg等元素,其中Fe,Zn,Mg等营养元素易于溶出,溶出率分别达61.8%,55.4%,61.4%。本研究为合理利用黄芩地上部资源提供了科学依据。
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 baicalensis 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.
