从成熟的普洱茶中分离到一种新的亚甲基二聚体黄酮醇苷，亚甲基双nicotiflorin(1)，并分离到10种已知的黄酮类化合物（2-11）和7种已知的酚类化合物（12-18）。结构解析是基于光谱分析。其中1,3-二羟基苯基-2- o -硫酸盐（13）、2,3,4-三羟基苯甲酸（16）和3,3,4,4-四羟基联苯（18）为首次从茶树中报道。
A new methylene-bridged dimeric flavonol glycoside, methylenebisnicotiflorin (1), was isolated from ripe Pu-er tea, along with 10 known flavonoids (2-11) and seven known phenolic compounds (12-18). The structure elucidation was based on spectroscopic analysis. Among them, 1,3-dihydroxyphenyl-2-O-sulfate (13), 2,3,4-trihydroxybenzoic acid (16) and 3,3,4,4-tetrahydroxybiphenyl (18) are reported from tea plants for the first time.
