摘要
应用微波消解样品,ICP-OES测定贵州道真仡佬族苗族自治县12个蒸青茶样和16个炒青茶样中的13种主要矿质元素。检测结果显示:茶叶样品中富含多种矿质元素,受茶树生长环境、茶树品种、加工方法等因素的影响,矿质元素含量差异明显。对矿质元素的相关性分析表明,茶叶元素之间存在明显的协同与拮抗作用。通过主成分分析可以分析茶叶矿质元素的特征性差异,对不同的茶叶样品进行分类。
Samples were digested using microwave,ICP-OES was used to determinat the 13 major mineral elements in the 12 steam fixed green tea samples and 16 Roasted tea samples which from Daozhen Gelao Hmong Autonomous County of Guizhou. Test results showed that ：tea samples rich in various mineral elements, because of the impact of the environment for the growth of tea,tea varieties,processing methods,mineral element content was different obviously. Mineral elements analysis was indicated that obvious synergy and antagonism existed between the tea element. Principal component analysis could analyze tea mineral elements characteristic differences to classify different tea samples.
