Comparison of catechins and purine alkaloids in albino and normal green tea cultivars (Camellia sinensis L.) by HPLC

► We quantified catechins, purine alkaloids, chlorophylls in albino and normal tea. ► Two locations were selected with different temperature. ► High temperature decreased catechin contents. ► Chlorophylls might affect catechin biosynthesis. ► Purine alkaloids were not significantly correlated with chlorophylls.
