Abstract

The study aimed to determine copper, chromium, cadmium, nickel, lead, zinc and manganese in four species of medicinal plants, widely used in phytotherapy, as well as to evaluate their transfer rate in aqueous preparations such as infusion, decoction and cold maceration. The medicinal plants were purchased randomly from local producers, near the city of Otopeni and analyzed using atomic absorption spectrometry. The results show that, at least one metal exceeds the maximum allowed level (Cd-0.08 mg/kg and Cu-12.9 mg/kg in rosemary, Cr-3.1 mg/kg in thyme and Pb-3.6 mg/kg in basil), the transfer rate of them, being variable in aqueous extractive solutions. The highest transfer rate of metals was observed in the case of cold maceration, the order of recovery being Mn > Zn > Cu > Ni > Cr > Cd > Pb. Quality food control is strictly necessary, so that, by implementing stricter legislation/monitoring programs at national level, can reduce the risk of contamination with toxins that can affect the integrity of human health.

摘要

该研究旨在测定广泛用于植物疗法的四种药用植物中的铜、铬、镉、镍、铅、锌和锰，并评估它们在输液、煎剂和冷浸等水性制剂中的转移率。药用植物是从奥托佩尼市附近的当地生产商处随机购买的，并使用原子吸收光谱法进行分析。结果表明，至少一种金属超过了最大允许水平（迷迭香中的 Cd-0.08 mg/kg 和 Cu-12.9 mg/kg，百里香中的 Cr-3.1 mg/kg 和罗勒中的 Pb-3.6 mg/kg），它们的转移率，在萃取水溶液中是可变的。在冷浸渍的情况下观察到金属的最高转移率，回收顺序为 Mn > Zn > Cu > Ni > Cr > Cd > Pb。
