摘要:

千两茶是由中国茶Camellia sinensis的芽叶经过微生物全发酵而成的一种黑茶。本研究通过色谱技术和重结晶等方法, 从该茶叶中分离纯化得到10个化合物, 经核磁与质谱等手段鉴定其结构, 分别为N-(2-羟苯基)-2-吡咯烷酮 (1), 对羟基苯乙酮 (2), salicifoliol (3), (-)-3-羟基-β-紫罗兰酮 (4), 对羟基肉桂酸乙酯 (5), ethyl 4-(sulfooxy)benzoate (6), (+)-罗汉松脂酚 (7), (-)-松脂素 (8), (+)-lirioresinol-A (9)和咖啡碱 (10)。其中化合物1为新天然产物, 化合物6为首次从山茶科植物中分离得到, 化合物3-57-9为首次从本种植物中分离得到。

Abstract:

Ten compounds were isolated from Qianliang tea, a kind of dark tea fully fermented from the leaves of Camellia sinensis (L.) O. Kuntze var. sinensis, and identified as N-(2-hydroxyphenyl)-2-pyrrolidinone (1), p-hydroxyacetophenone (2), salicifoliol (3), (-)-3-hydroxy-β-ionone (4), p-hydroxy ethyl cinnamate (5), ethyl 4-(sulfooxy)benzoate (6), (+)-matairesinol (7), (-)-pinoresinol (8), (+)-lirioresinol-A (9), and caffeine (10), among which compound 1 was isolated as a new natural product, and compound 6 was isolated from Theaceae family for the first time. Compounds 3, 4, 5, 7, 8, and 9 were isolated from this species for the first time.

Key words: Qianliang tea, Camellia sinensis, Alkaloids, Phenolic derivatives, Lignans
