PROBLEM TO BE SOLVED: To provide a tea leaf extract richly including anthocyanin having high stability and excellent palatability: and to provide a method for producing the tea leaf extract.SOLUTION: A tea leaf extract includes 0.13 wt.% or more of delphinidin or its glycoside and 23.0 wt.% or less of catechin to a dry weight of the leaf extract. A method for producing tea leaf extract extracts tea leaves using water in an amount 10 times or more the dry weight of the tea leaves under the condition of a temperature at 70-95°C and a period of time of 5-60 min. It is preferable that the ratio of the content of the delphinidin occupied in the content of anthocyanin or its glycoside is 50% or more, epigallocatechin gallate is included at 10.5 wt.% or less to the dry weight of the tea leaf extract, and caffeine is included at 5.4 wt.% or less, and amino acid is included at 1.0 wt.% or more.SELECTED DRAWING: NoneCOPYRIGHT: (C)2018,JPO&INPIT【課題】安定性の高いアントシアニンを豊富に含み、かつ、嗜好性の優れた茶葉抽出物及びその製造方法の提供。【解決手段】茶葉抽出物の乾燥重量に対してデルフィニジン又はその配糖体０．１３重量％以上とカテキン類２３．０重量％以下とを含む茶葉抽出物、茶葉を茶葉乾燥重量の１０倍量以上の水を用いて、温度７０～９５℃、時間５～６０分の条件で抽出する茶葉抽出物の製造方法。アントシアニンの含有量に占めるデルフィニジンまたはその配糖体の含有量の比率が５０％以上であり、エピガロカテキンガレートを茶葉抽出物の乾燥重量に対して１０．５重量％以下含み、カフェインを５．４重量％以下含み、アミノ酸を１．０重量％以上含むことが好ましい。【選択図】なし
