摘要: 采用原子吸收光谱法测定广东省清远市、梅州市及河源市3个地区茶叶样品中钙(Ca)、镁(Mg)、铁(Fe)、锰(Mn)、锌(Zn)、铜(Cu)6种矿质元素的含量,采用国家标准方法测定茶样中水分、干物质、水浸出物、茶多酚、氨基酸及可溶性糖含量,并通过多总体均值向量检验法分析了这3个地区茶叶中矿质元素、生化成分含量的差异。结果表明,部分地区茶叶中矿质元素、生化成分含量之间存在显著差异。

关键词: 茶叶, 地区, 矿质元素, 多总体均值向量检验法

Abstract: The contents of Ca,Mg,Fe,Mn,Zn and Cu in the samples from Qingyuan city,Meizhou city and Heyuan city in Hubei province were determined by atomic absorption spectrometry. The contents of water,dry matter,water extract,tea polyphenols,amino acids and soluble sugar in tea samples were determined by national standard method. The difference of mineral elements and biochemical components in tea leaves was analyzed by multi population mean value vector test. The results showed that the contents of mineral elements or biochemical components in some tea leaves were significantly different.

Key words: tea, region, mineral element, multiple population mean vector test
