Which phenolic compound is found in tea?

The major phenolic acids found in tea are gallic acid, chlorogenic acid and theogallin which account for 0.5–1.4%, 0.3% and 1–2%, respectively of dry weight content. Whereas ellagic acid and m-digallic acid are found in trace amounts.

Which tea has the highest polyphenols?

Wushwush green tea
Results: Wushwush green tea had the highest content of polyphenol (19.98 ± 1.15 mg gallic acid equivalent /100 g dry leaf weight), catechin (37.06 mg/g) and L-theanine (48.54 mg/g but the lowest caffeine content). It exhibited the highest antioxidant activity.

Do all teas have polyphenols?

Which tea has the most EGCG?

Green tea
Green tea generally has the highest amounts of EGCG, while oolong and black tea have significantly less[3] because they are either partially or fully oxidized. Teas made from Camellia sinensis var. Sinesis have higher EGCG content than teas made from assamica tea plant[4].
