中药三七中5种微量元素的含量及健康风险

为了解三七中Fe、Mn、Al、Zn、Se人体微量元素的含量,并客观评价这5种微量元素对长期服用三七药品的患者的健康风险,在三七的产区及周边市县进行采样,采用电感耦合等离子体质谱仪(ICP-MS)对三七中这5种微量元素的含量进行测定,并采用点推定和概率推定对各元素的非致癌风险危害商值(HQ)值进行评估,结果发现三七中5种微量元素的平均含量分别为1375.84,108.31,1213.62,0.16,21.99mg/kg,表现出AlFeMnZnSe的高低顺序,HQ值大小顺序为FeAlMnZnSe.HQ值均小于1,提示针对各元素,一般消费者不存在非致癌健康风险.然而,Fe,Al,Mn的日摄入量分别为0.09573,0.10759,0.00832mg/(kg·d),超出了来源于药物的微量元素的经口允许摄入量,应该加以控制.对危害指数(HI)的概率推定结果显示,5.19%的三七服用者对这5种微量元素的暴露具有非致癌健康风险.

The contents of five trace elements in Panaxnotoginseng and the associated health risk

In order to investigate the contents of Fe、Mn、Al、Zn、Se in Panaxnotoginseng (Sanchi) and evaluate the health risk of these elements for long-term consumers of Sanchi preparations, samples of Sanchi roots were collected in traditional production region and the surrounding areas. The contents of the five trace elements in Sanchi were analyzed by ICP-MSand the non-carcinogenic health risk was evaluated by deterministic estimation and probabilistic estimation. The results show that the average contents of the five trace elements in Sanchiare 1375.84, 108.31, 1213.62, 0.16, 21.99mg/kg, decreased in the order: Al > Fe > Mn > Zn > Se and the order of the hazardous quotient (HQ) values is Fe > Al > Mn > Zn > Se. The HQ valuesare all below 1, implying no non-carcinogenic health riskof individual element for general consumers. However, daily intakes of Fe, Al and Mnare 0.09573, 0.10759, 0.00832mg/(kg·d), which are beyond the corresponding limits for tolerable oral intake from medicinal plants and should be controlled. Probabilistic distribution of hazardous index (HI) values of 5trace elements due to consumption of Sanchi preparation shows that 5.19% of theconsumers havenon-carcinogenic health risk.
