摘  要:
为了解云南榧树不同部位矿质元素的质量分数,采用HNO3-HF-HClO4湿法消解样品,电感耦合等离子体发射光谱法(ICP-OES)测定了树皮、木质部和叶片中的20种矿质元素质量分数,结果表明:云南榧树不同部位均富含矿质元素,其中Ca、K、Mg、P、Na、Fe、Cr、Zn、Mn等质量分数较高,与其药用价值具有相关性。另外,树皮和叶含有害微量元素Pb和As,在进行药用时,应考虑其带来的风险。

摘  要:
Torreya yunnanensis samples were digested by HNO3-HF-HClO4 method to study element contents in different parts of T.yunnanensis.Twenty mineral elements in the bark,xylem and leaves of T.yunnanensis were determined by Inductively Coupled Plasma Optical Emission Spectrometer(ICP-OES).Results show that T.yunnanensis is rich in mineral elements.The contents of Ca,K,Mg,P,Na,Fe,Cr,Zn,and Mn are high,which have some correlation with its drug effect.However,harmful trace elements of Pb and As were detected in the bark and leaves of T.yunnanensis.The risk should be considered for medical purposes.
