Provided is a process for producing a tea extract having a high recovery rate of non-polymer catechins, a low caffeine content and an improved taste and color tone. As one embodiment of this invention provides, there is provided a process for producing a purified tea extract by adsorbing a tea extract on a synthetic adsorbent, bringing an aqueous solution of an organic solvent or a basic aqueous solution into contact with the synthetic adsorbent to elute non-polymer catechins, and then bringing the eluate into contact with activated carbon in an aqueous solution of an organic solvent.
