    New dibenzotropolone derivatives characterized from black tea using LC/MS/MS
    摘要:
    Theaflavins and thearubigins are major pigments in black tea, and it is generally accepted that they are produced by oxidation of flavan-3-ols (catechins) during tea fermentation. In the course of studies on the oxidation mechanism of tea polyphenols, especially the formation of thearubigins, a method combining the enzymatic synthesis and LC/ESI-MS/MS analysis was developed to search for new higher molecular weight polymers from black tea. Three new dibenzotropolones, theadibenzotropolone A, B, and C, together with one new tribenzotropolone, theatribenzotropolone A, were formed by the reaction of theaflavins and tea catechins with horseradish peroxidase in the presence of H2O2. The structures of these new benzotropolone derivatives were elucidated on the basis of MS and 2D NMR spectroscopic analyses. The existence of these compounds in black tea was characterized by LC/ESI-MS/MS. Theadibenzotropolone A and B were the first benzotropolone-type trimers of catechins found in the black tea extract. The observation that galloyl ester groups of theaflavins can be oxidized to form di- or tri-benzotropolone skeletons strongly implied that this type of oxidation is an important pathway to extend the molecular size of thearubigins.

When the enzymatic reaction proceeded in a buffer solution, oxidized ()-epigallocatechin gallate was preferentially used for self-dimerization. However, self-dimerization was suppressed in the octanol phase, allowing oxidized ()-epigallocatechin gallate to participate in coupling with ()-epicatechin quinone, leading
    茶黄素是红茶中的橙红色色素,由于其促进健康的作用而引起了人们的关注。然而,他们的合成制备方法,其中邻苯二酚型儿茶素的酶促氧化,随后由苯醌诱导的选择性结合的邻苯二酚和邻苯三酚型儿茶素的氧化二聚化,仅提供了低产率。在本研究中,我们发现1-辛醇/缓冲液双相系统在酪氨酸酶催化的(-)-表儿茶素和(-)-表没食子儿茶素没食子酸酯的合成反应中提高了茶黄素3-没食子酸酯的收率。当酶反应在缓冲溶液中进行时,氧化的(-)-表没食子儿茶素没食子酸酯优先用于自二聚。但是,在辛醇相中自二聚被抑制,使氧化的(-)-表没食子儿茶素没食子酸酯参与与(-)-表儿茶素醌的偶合,导致茶黄素3-没食子酸酯的有效生产。此外,茶黄素3-没食子酸酯在辛醇相中的优先定位阻止了(-)-表儿茶素-醌诱导的降解。
