Abstract

Notable seasonal changes of the levels of purine alkaloids caffeine and theobromine in shoot leaves and shoots of tea (Camellia sinensis L.) were observed suggesting transformation and/or translocation of the alkaloids. The alkaloids decreased significantly in August and in October and November while total nitrogen increased appreciably in November and December. The results indicated that the alkaloids have no role in the storage of nitrogen during the winter months
