Oolongtheanins, catechin dimers derived from oolong tea leaves, were isolated by Hashimoto et al. in 1988. Later, Tanaka et al. revised the oolongtheanin structure. In this study, it was clarified that oolongtheanins in organic solvent like acetone or methanol have the structures proposed by Tanaka et al. Based on the hydrogen/deuterium exchange reaction in aqueous solution, it was suggested that they
桥本等人从乌龙茶中提取了儿茶素二聚体-卵磷脂。1988年。后来,田中等人。修改了乌龙茶素的结构。在这项研究中,澄清了乌龙茶素在有机溶剂如丙酮或甲醇中具有Tanaka等人提出的结构。基于水溶液中的氢/氘交换反应,表明它们以桥本和田中提出的结构的平衡混合物形式存在。
