Abstract

Caffeine is an important purine alkaloid of methyl xanthine family present in beans of coffee. Caffeine content was determined in developing fruits of robusta coffee plant (Coffea canephora), that collected from plants grown at different elevations to find out the influence of altitude on caffeine content. Caffeine levels were analysed by performing High Performance Liquid Chromatography (HPLC). Caffeine content was found always more at all stages of coffee fruit ontogeny from plants grown at low elevations. The proportion of increase in caffeine content was more from the stage II (4 months) to stage III (5 months). Maximum caffeine content of 1.868 ± 0.149 g/100 g dry weight was evident in stage V seeds (9 months) of low altitude collected samples. There was a 32% reduction in caffeine content of beans from plants grown at high elevations.
