| 中文摘要: |
| 本文测定了野生采集和人工培育冬虫夏草、人工培育冬虫夏草子实体、冬虫夏草发酵菌液、冬虫夏草寄主蝙蝠蛾昆虫食物（蕨麻 Potentilla anserine 和珠芽蓼 Polygonum viviparum ），以及野生冬虫夏草产地土壤中5种重金属元素（铜Cu、铅Pb、砷As、镉Cd、汞Hg）的含量。结果表明，人工培育冬虫夏草、人工培育冬虫夏草子实体、冬虫夏草发酵菌液、蕨麻块根、珠芽蓼种子的5种重金属元素含量符合《中医药-中药材重金属限量》ISO国际标准；而野生冬虫夏草，除砷含量（6.170 mg/kg）超标外，铜、铅、镉、汞元素含量均符合要求。按国家标准《土壤环境质量农用地土壤污染风险管控标准（试行）》（GB1516-2018），四川产地土壤（KDX）与青海产地土壤（GD、HN）的5种重金属含量均低于农用土壤污染风险筛选值；而四川产地土壤（KDT），除镉含量（0.923 mg/kg）高于风险筛选值而低于风险管制值外，其余4种元素含量均低于风险筛选值。结果为人工培育冬虫夏草的质量控制提供了参考。 |
| 英文摘要: |
| The content of 5 heavy metals (Cu, Pb, As, Cd, Hg) in natural and cultivated Ophiocordyceps sinensis, fruiting bodies and fermentation broth of O sinensis, habitat plants ( Potentilla anserine and Polygonum viviparum ) and habitat soil of natural O sinensis were determined in this paper. The results showed that the contents of five heavy metal elements in cultivated O sinensis, fruiting bodies and fermentation broth of O sinensis, P. anserine root tuber and P. viviparum seeds were in accordance with the ISO international standard of “Chinese Medicine Chinese Herbal Medicine Heavy Metal Limit”. While in the natural O sinensis, except the excess of arsenic element (6.170 mg/kg), the other 4 elements (Cu, Pb, Cd and Hg) meet the requirements According to the national standard “Soil Environmental Quality Risk Controls Standard for Soil Contamination of Agricultural Land (trial)”(GB1516-2018), the contents of five heavy metals in Sichuan habitat soil (KDX) and Qinghai habitat soil (GD, HN) are lower than the risk screening values for soil contamination of agricultural land. In Sichuan habitat soil (KDT), except cadmium content (0.923 mg/kg) is higher than the risk screening value and lower than the risk intervention value, the content of the other four elements is lower than the risk screening value. The results provided a reference for the quality control of cultivated O. sinensis. |
