چکیده مقاله:
Tea (Camellia sinensis L.) is a plant rich in antioxidant compounds in the world and due to weather condition, season, age and genetic diversity the compounds of tea are different due to weather conditions. In this study, fresh tea shoots of clones 100, 278, 451 and DN, in three harvest seasons (spring, summer, and autumn) were collected from Tea Research Institute of Iran (Lahijan). Quercetin content, caffeine, and catechin were assayed using HPLC. The results of this study showed that the amount of these antioxidant compounds changed significantly from first harvest (spring) to third harvest (autumn) under seasonal changes. So, it can be said that environmental changes in different season are the determining factor for the biochemical composition changes of tea clones
