Abstract：A study was carried out on the contents of six trace elements, Ca, Cu, Fe, Mn, Zn and K, in roots, stems, leaves, flowers and seeds of planted Scutellaria baicalensis, by flame atomic absorption spectrophotometry (FAAS). The results indicated that Scutellaria baicalensis was rich in trace elements, meaning that it has a relatively high nutritive value. In stems of Scutellaria baicalensis, the content sequence of the six trace elements was found to be Fe＞Mn＞Zn=Cu＞K＞Ca. In leaves, the content sequence of the six trace elements was Fe＞Mn＞Zn＞Cu＞K＞Ca. In flowers and seeds it was Ca＞Fe＞Mn＞Zn＞Cu＞K, and Ca＞Fe＞Zn＞Mn＞Cu＞K, separately, and in roots it was Ca＞Fe＞Cu＞Mn＞Zn＞K. The stems, leaves, flowers and seeds are rich in Fe, whose content is higher than that in pork liver, Mn and Zn, but lower in Ca. The flowers, seeds and roots are especially rich in Ca, whose content is higher than that in bone, indicating that different parts of Scutellaria baicalensis may accumulate different mineral element. This study, for the first time, researched into Ca, Cu, Fe, Mn, Zn and K contents in different parts of Scutellaria baicalensis, which helps explain the multifunction of Scutellaria baicalensis and provides theoretical basis for further developing its medical and edible value.
