En: Genetic Resources and Crop Evolution (Países Bajos) v. 40 p. 61-70Resumen: The extent and nature of biochemical diversity in green coffee beans was established by a large sampling of genus Coffea, representing nine species form the Guineo-Congolian region, nine species from East Africa and seven species from Madagascar. HPLC analyses were used to determine the contents of caffeine, chlorogenic acids and mozambioside. Data processed by principal component analyses showed the existence of two metabolic pathways. One leads to the synthesis of small quantities of chlorogenic acids (<2.5 per cent dmb) and caffeine <0.3 per cent dmb) while the other leads to large concentration of chlorogenic acids (>4.5 per cent dmb) and caffeine (>0.4 per cent dmb). Their distribution in the genus Coffea is discussed in relation to the biogeographic origin of the plant material.
