Tea saponins (theasaponins) are concentrated in tea seeds and flowers but are also present in leaves. They contribute a mild bitterness distinct from catechin astringency. Tea saponins have demonstrated anti-inflammatory and antimicrobial properties, and their surfactant nature may enhance absorption of other bioactive compounds.
