text: The second step involves adsorbing the caffeine-free mixture of catechins onto a second reversed phase matrix followed by the specific desorption of catechins using specific eluents, and then evaporating selected fractions to afford caffeine-free mixture of catechins of substantial purity, the majority of the catechin mixture comprising EGCG.
