[10] [11] Tea has one of the highest contents of flavonoids among common food and beverage products. [7] Catechins are the largest type of flavonoids in growing tea leaves. [6] According to a report released by USDA, in a 200-ml cup of tea, the mean total content of flavonoids is 266.68 mg for green tea, and 233.12 mg for black tea. [7]
It is found in high content in the dried leaves of green tea (7380 mg per 100 g), white tea (4245 mg per 100 g), and in smaller quantities, black tea (936 mg per 100 g). [2] During black tea production, the catechins are mostly converted to theaflavins and thearubigins via polyphenol oxidases .
Epicatechin gallate (ECG) is a flavan-3-ol, a type of flavonoid, present in green tea. [1] It is also reported in buckwheat [2] and in grape. [3]The tea component epicatechin gallate is being researched because in vitro experiments showed it can reverse methicillin resistance in bacteria such as Staphylococcus aureus. [1]

Kukicha (also known as bōcha or 'twig tea') is made primarily from the twigs and stems of the tea plant rather than the leaves alone. [4] Hōjicha infusions have a light- to reddish-brown appearance and are less astringent. The lower levels of astringency in hōjicha are due to the tea losing catechins during the high-temperature roasting process.

All tea leaves contain fluoride; however, mature leaves contain as much as 10 to 20 times the fluoride levels of young leaves from the same plant. [9] [10]The fluoride content of a tea leaf depends on the leaf picking method used and the fluoride content of the soil from which it has been grown; tea plants absorb this element at a greater rate than other plants.
