广东阳春双滘原产地产品沙姜的特征元素

植物特征元素及其组合能一定程度上反映特定区域对该地植被生长产生的影响。为了探讨元素及其组合能否作为原产地产品的元素指纹标记,分析了广东阳春双滘地区沙姜与土壤中十多种元素的含量、相关性及元素吸收系数。该研究中微量元素在沙姜和土壤中均具有较好的传承性;沙姜对各种元素的吸收具有差异性,沙姜与土壤中元素也具有一定的相关性;通过权重分析初步认定该区域沙姜特征元素为Mn、Zn、Mg、Sr、Cu、Ni、Fe。区域地球化学背景对原产地产品的影响值得深入探讨。

Characteristic elements of Kaempferia Galanga L. from Yangchun in Guangdong Province

The characteristic elements and their assembly of plant can indicate the effect of special geochemical environment on the local plant. In this paper fourteen trace elements in soil and Kaempferia Galangal L samples were measured to explore the feasibility of characteristic elements as the fingerprinting marker of products of origin in Shuangjiao of Yangchun region. The results showed that: there was a significant correlation between the contents of trace elements in soil and in plant; the absorptive capacities of Kaempferia Galangal L. to trace elements were different; Mg, Mn, Zn, Sb, Fe, Cu and Sr were the characteristic elements of Kaempferia Galangal L. by weight analysis. Effect of regional geochemical background on the products of origin should be further explored.
