| Abstract: | Kuding tea leaves are clssified as four grades according to the growth position of leaves.The contents of trace elements and flavone of four grade leaveswere respectively determined by inductivelycoupled plasma spectrometry and spectrophotometry.The results showed that the contents of trace elementsand flavone in th different position leaves have some difference.The content of flavonein the fourth grade leavesis lowest. |
