Abstract
The contents of dalichasu (1,2-di-O-galloyl-4,6-O-(S)-hexahydroxydiphenoyl-β-D-glucopyranose),catechins,theogallin,gallic acid,caffeine and theanine in old tea trees from Bai-Ying-Shan mountain were quantitatively analyzed by HPLC method,while their total polysaccharides and polyphenols were measured by an UV-Vis spectrophotometer. Based on the chemical composition and morphological variation,the germplasm resource diversity of tea trees in Bai-Ying-Shan Mountain and their relationship with wild Camellia taliensis and cultivated tea (C.sinensis var. assamica) were discussed. The results provided not only the scientific data of quality evaluation of the old tea trees in Bai-Ying-Shan Mountain,but also the chemical evidence for the origin of cultivated tea and the hypothesis that C.taliensis might be one of the origins of cultivated tea during the long natural variation and artificial breeding.
采用高效液相色谱法定量分析了白鹰山老茶树中大荔枝素(1,2-二- o -没食子-4,6- o -(S)-六羟基二酚-β- d -葡萄糖吡喃糖)、儿茶素、没食子素、没食子酸、咖啡因和茶氨酸的含量，并用紫外-可见分光光度计测定了总多糖和总多酚的含量。从化学成分和形态变异的角度，探讨了白莺山茶树种质资源多样性及其与野生茶树和栽培茶树的关系。研究结果不仅为白应山老茶树质量评价提供了科学依据，而且为栽培茶的起源提供了化学依据，并在长期的自然变异和人工育种过程中提出了塔里茶可能是栽培茶的起源之一的假设。
