嫩梢的芽、叶和茎均为紫色的茶树品种“紫娟”茶(Camellia sinensis var.assamica)的花青素和其他类黄酮含量比其他大叶种茶树鲜叶含量高.本文建立了“紫娟”茶的黄酮醇类物质的高效液相色谱检测方法,应用该方法测定了不同成熟度新梢的杨梅素类、槲皮素类、山柰酚类和总黄酮醇苷的含量.结果表明,杨梅素类以一芽三叶新梢含量最高(2.29mg/g),一芽二叶新梢、一芽一叶新梢和成熟叶的含量依次分别是2.08 mg/g,1.69 mg/g和…查看全部>>
"Zijuan" tea is a new Camellia sinensis var. Assamica cultivar, which accumulates more an-thocyanins and other flavonoids than other varieties in its purple fresh buds, leaves and stems. In this paper, a HPLC procedure to determinate the contents of flavonols in "Zijuan" tea were established and the compositions and distribution of flavonols in the fresh shoots of "Zijuan" tea were detected. The results showed that the highest content of myricetin were detec…查看全部>>
