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.本發明係提供一種茶萃取物之製造方法,其中該茶萃取物之非聚合物兒茶素類回收率較高、咖啡因含量較低、呈味及色調得以改善。本發明之一形態係純化茶萃取物之製造方法,係使茶萃取物吸附於合成吸附劑後,使有機溶劑水溶液或鹼性水溶液接觸合成吸附劑,將非聚合物兒茶素類溶出,繼而於有機溶劑水溶液中使溶出液接觸活性碳。
