title: [Analysis of the content of mineral elements in Scutellaria baicalensis, skullcap tea and its solution].
abstract: 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.
