摘要
目的:通过对不同产地梅花鹿鹿茸中矿物质元素含量分析,研究鹿茸的道地性及安全性。方法:从吉林省和山东省7个梅花鹿养殖区收集了42份鹿茸样品,冻干处理保存,采用微波消解-电感耦合等离子体质谱(ICP-MS)法测定样品中18种矿物质元素含量,统计分析不同产地样品中矿物质元素含量的差异。同时,采用主成分分析对所有样品进行聚类以及皮尔逊相关性系数分析,阐明18种矿物质元素之间的相关性。结果:不同产地鹿茸中所测多数矿物质元素含量存在差异性,其中Zn含量吉林省鹿茸极显著低于山东省鹿茸;重金属元素Pb、Cd、Cu、As在鹿茸中含量很低,均在食品重金属含量允许范围内。结论:ICP-MS方法可准确测定冻干鹿茸中矿物质元素含量,不同产地间存在差异,不同产地样品中矿物质元素含量存在相关性;Zn含量可以作为单一相关的候选因素,研究鹿茸的道地性;以重金属元素为指标,鹿茸作为食品和药材的原材料是安全的。
Objective :To investigate the geoherbalism and safety of sika deer velvet antlers,mineral element contents in the antlers from different areas of origin were measured and analyzed. Method: 42 velvet antler samples were collected from 7 sika deer farms in both Jilin and Shandong Provinces.The contents of 18 mineral elements in the samples were measured by using ICP-MS after freeze-drying for preservation.At the same time,principal component analysis was used to cluster all samples and Pearson correlation coefficient analysis was carried out to clarify the correlation between the 18 mineral elements. Results: Contents of most mineral elements in the velvet antlers from different areas of origin varied considerably,and the Zn content in Jilin was lower than that in Shandong;Contents of Pb,Cd,Cu and As in the velvet antler were much lower than limits of Pharmacopoeia of the People′s Republic of China,all in the range of food heavy metals. Conclusion: There was a correlation between mineral element contents in the antler samples from the same area.ICP-MS could accurately be used to measure the contents of mineral elements in freeze-dried velvet antlers,and there were differences in mineral contents among the different producing areas.To study geoherbalism of velvet antlers,Zn content could be used as a single candidate factor.Based on the fact that velvet antlers contain very low heavy metals,velvet antlers are a safe raw material for food and medicine.
