- Abstract
In order to compare the physical and chemical quality of Hawk tea ( Litsea coreana var. sinensis) in four counties of Guizhou Province, the biochemical compositions and mineral elements of the Hawk tea processed in four counties of Guizhou Province were determined according to the traditional iron pot and slow fire drying process. The results showed that the content of biochemical compositions of Jiangkou Hawk tea was higher, especially the highest content of total flavonoid and the better quality; However, its heavy metal lead content exceeded the standard, which did not meet the requirements. Content of biochemical compositions of Xifeng sample was also high with the highest content of tea polyphenol and water extract, and the total flavone content was next to Jiangkou sample. The content of trace elements zinc, magnesium and selenium were also high and the content of heavy metals met the national standards with good quality, too. Moreover, Jiangkou Hawk tea had the most kinds of amino acid components ; Meitan sample had the least kind of amino acid components; Chishui sample had a high content of trace metal elements and contained caffeine, and had a high content of amino acid with fresh taste, which was specific. The four Hawk tea in different counties in Guizhou Province had different characteristics in physical and chemical quality.
