摘要：分析线叶金雀花茶的饮用安全性，为其加工和质量控制提供参考。采用电感耦合等离子体发射光谱法（inductively coupled plasma-atomic emission spectroscopy，ICP-AES）测定线叶金雀花茶中的钾、钙、钠、镁、磷、铁、锌、锰、铜、砷、铅、镉12种矿物质元素含量，并研究基于冲泡时间和冲泡次数对矿物质元素溶出率的影响，探讨其饮用安全性。结果表明：中国、南非2种不同产地的样品中矿物质元素含量排序均为钾＞钠＞钙＞镁＞磷＞铁＞锰＞锌＞铜，波兰样品中矿物质元素的含量排序为钠＞钾＞钙＞镁＞磷＞铁＞锰＞锌＞铜，砷、铅、镉在三种样品中均未检出，三种样品中铁元素含量差异显著（P＜0.05），除铁元素外，南非和波兰的线叶金雀花茶中矿物质元素的含量无显著差异（P＞0.05）。通过对矿物质元素的溶出特性进行探讨，线叶金雀花茶可在90℃、冲泡5min条件下，冲泡2次；在此条件下，人体通过饮用线叶金雀花茶摄入过量钙、磷、铁、锌、铜、锰、砷、铅、镉元素的风险较低。鉴于矿物质元素摄入量的可获得性和可承受性，线叶金雀花茶能补充少量的矿物质元素，是一种良好的饮品原料。

Abstract：To study drinking safety of Aspalathus linearis and provide reference for processing and quality control of it，inductively coupled plasma-atomic emission spectroscopy （ICP-AES） was used to analyze the content of twelve minerals including K，Ca，Na，Mg，P，Fe，Zn，Mn，Cu，As，Pb，Cd in Aspalathus linearis and its drinking safety was discussed based on mineral dissolution rate affected by boiling time and boiling frequency. Results showed that the order of mineral elements in the two samples from China and South Africa was K＞Na＞Ca＞Mg＞P＞Fe＞Mn＞Zn＞Cu，order of mineral elements in the sample from Poland was Na＞K＞Ca＞Mg＞P＞Fe＞Mn＞Zn＞Cu and As，Pb，Cd were not detected in all three samples. The content of iron in three samples differed obviously （P＜0.05） and no significant differences （P＞0.05） were observed in the content of mineral elements （except iron） between samples from South Africa and Poland. By discussing the dissolution characteristics of mineral elements，it was found that Aspalathus linearis could be boiled twice at 90 ℃ for 5 min. Under these conditions，the risk of excessive intake of Ca，P，Fe，Zn，Cu，Mn，As，Pb and Cd was low. Considering the availability and allowance of mineral elements intake，Aspalathus linearis can supplement a little of mineral elements and is a good drinking material.
