摘要
目的比较梅花鹿三叉茸不同加工方式及不同区段20种矿物质元素(Na、Mg、Al、P、K、Ca、Mn、Fe、Co、Ni、Cu、Zn、Se、Cr、As、Cd、Ag、Pb、Ba、Au)含量的差异,旨在为鹿茸的合理利用及鹿茸药效价值的有效挖掘提供参考。方法采用湿法消解和微波消解对采集自吉林地区的梅花鹿三叉茸进行预处理,利用电感耦合等离子质谱(ICP-MS)方法测定矿物质元素含量。结果所测样品中Cd元素和Ag元素检出结果均小于0.001μg/kg。Na、Mg、Al、P、K和Ca在鹿茸中含量较高,尤其是Ca含量,从鹿茸尖部蜡片区到基部骨片区大幅度增加,骨片区Ca质量分数高达148.6~164.4 g/kg。元素Na、Mg、Al、P、K和Ca在不同区段之间含量差异显著(P<0.05);元素Mn、Cu、Zn和Ba在鹿茸中含量高于Fe、Co、Ni、Se和Cr。重金属元素Cr、As、Au和Pb在鹿茸中含量很低,在食品重金属限量范围内。鹿茸中富含Se元素,从骨片至蜡片Se元素含量逐渐提高,蜡片区质量分数为260.35~357.29μg/kg。烘干处理和冻干处理2种方式对鹿茸中Al等元素含量有显著影响(P<0.05),整体水平呈现Al、P和Ca含量煮炸茸高于冻干茸,Na、Mg和K含量煮炸茸低于冻干茸的规律。结论不同初加工方式对三叉鹿茸部分矿物质元素含量有影响,不同区段体现出不同的规律;鹿茸不同区段之间矿物质元素含量差异很大,不同区段发挥不同的药用价值,研究结果能有效指导科学使用鹿茸。
Objective To compare the contents of mineral elements（Na, Mg, Al, P, K, Ca, Mn, Fe, Co, Ni, Cu, Zn, Se, Cr, As, Cd, Ag, Pb, Ba, and Au） in different parts of Cervi Cornu Pantotrichum（CCP） with different processing methods, with aims to provide a guidance for the effective utilization and determination of medicinal value of CCP. Methods The three-branched velvet antler collected from Jilin Province was pretreated by microwave digestion and wet digestion, and the content of elements was determined by inductively coupled plasma mass spectrometry（ICP-MS）. Results The results of detection of Cd and Ag in samples were all less than 0.001 μg/kg. Higher contents of Na, Mg, Al, P, K, and Ca were observed in antler samples especially the content of Ca which increased sharply from wax to bone section. The content of Ca reached to 14.86%—16.44% in the bone section. The contents of Na, Mg, Al, P, K and Ca were significantly different in different sections（P 0.05）. The contents of Mn, Cu, Zn, and Ba were relatively higher than Fe, Co, Ni, Se, and Cr in antlers. The contents of Cr, As, Au, and Pb were very low within the limits of heavy metals of food. Se was rich in antler sample which contains 260.35—357.29 μg/kg in wax section. Drying and freeze-drying treatments had significant differences in Al and other elements（P 0.05）. The overall level presented that the contents of Al, P, and Ca in the boiled fry were higher than those in frozen dried antler, however, Na, Mg, and K were the opposite. Conclusion Different initial processing methods affected the contents of some mineral elements in three-branched velvet antler, and different sections showed different rules. The content of mineral elements in different sections of velvet antler varied greatly. This study provides a theoretical basis for the fine use of antler in different sections.
