Abstract

Fourteen mineral and trace elements (Al, Ba, Ca, Cd, Co, Cr, Cu, Fe, Mg, Mn, Ni, Pb, Sr and Zn) were determined in the herbs and their infusions consumed for medical purposes in Turkey such as chamomile (Matricaria chammomile L.), fennel (Foeniculum vulgare), linden (Tilia vulgaris), nettle (Urtica dioical), rosehip (Fr.Rosa caninae), sage (Salvia officinalis) and senna tea (Cassia anqustifolia). Microwave digestion procedure was applied under optimized conditions for dissolution of medicinal herbs. Element concentrations in the medicinal herbs and their infusions were determined by FAAS and ICP-AES. The accuracy and precision were verified against a GBW 07605 Poplar leaves and Tea certified reference material. The mineral and trace element content of medicinal herbs and their infusions showed a wide variability. However, distribution of the elements in the infusions is not high and it is nil especially for Cd, Co, Cr and Pb.

摘要

测定了土耳其用于医疗目的的草药及其浸液中的14种常量和微量元素（铝、钡、钙、镉、钴、铬、铜、铁、镁、锰、镍、铅、锶和锌），这些草药包括洋甘菊（母菊）、茴香（小茴香）、椴树（欧洲椴树）、荨麻（异株荨麻）、玫瑰果（犬蔷薇）、鼠尾草（药用鼠尾草）和番泻叶茶（窄叶决明）。在优化条件下采用微波消解程序溶解草药。通过火焰原子吸收光谱法（FAAS）和电感耦合等离子体发射光谱法（ICP - AES）测定草药及其浸液中的元素浓度。对照GBW 07605杨树叶和茶叶标准物质验证了准确性和精密度。草药及其浸液中的常量和微量元素含量差异很大。然而，浸液中元素的分布不高，尤其是镉、钴、铬和铅的含量为零。
