  Disclosed is a method for cheaply and easily producing theaflavins. After adding a large quantity of water to raw tea leaves that have not undergone wilt treatment, the tea leaves are crushed in a blender and then let stand, shaken, or agitated, thereby efficiently convening four types of catechins in the raw tea leaves to theaflavins. After adding water and crushing the raw tea leaves, letting the tea leaves stand allows theaflavins to be selectively obtained with high yield. Shaking the raw tea leaves which have had water added and been crushed allows four types of theaflavins to be obtained with high yield. The generated theaflavins can be easily collected using a method such as extraction by organic solvent.

  本发明公开了一种便宜且容易生产茶黄素的方法。将未经凋萎处理的生茶叶加入大量水中，将茶叶在搅拌器中研磨后静置、摇晃或搅拌，从而有效地将生茶叶中的四种儿茶素转化为茶黄素。在加水和研磨生茶叶后，让茶叶静置可高效地选择性地获得茶黄素。将加水和研磨后的生茶叶摇晃可高效地获得四种茶黄素。可使用有机溶剂提取等方法轻松地收集所产生的茶黄素。

  The present invention provides a method for selective production of theaflavin in large amounts at high yield, and in an easy and inexpensive manner. Specifically, it relates to a method for selective production of theaflavin whereby a processed plant extract containing epicatechin, epigallocatechin, epicatechin-3-O-gallate and epigallocatechin-3-O-gallate is combined with a plant cell culture having peroxidase activity for selective production of theaflavin.

  本发明提供了一种在高产量和易于且低成本的情况下选择性大量生产茶黄素的方法。具体而言，它涉及一种选择性生产茶黄素的方法，其中将含有表儿茶素，表儿茶素3-O-没食子酸酯和表儿茶素-3-O-没食子酸酯的加工植物提取物与具有过氧化物酶活性的植物细胞培养物结合，以选择性地生产茶黄素。
