Objective: To make phy.ochemical studies of the leaf, pericarp and seed of Coffea benghalensis(C. Benghalensis) compared with those of the widely.known Coffea arabica and Coffea liberica. Methods: The sample extracts were prepared by.Soxhlet-extraction. Poly.henol content was analy.ed by.HPLC-ESI-MS/MS, the identification was carried out based on the retention time, UV and mass spectra of standards and literature data of the detected compounds. Results: Phenolic acids like caffeoy.quinic acids, dicaffeoy.quinic acids, feruloy.quinic acids and coumaroy.quinic acid, as well as mangiferin were detected as main constituents in all extracts. Procy.nidin trimers were present exclusively.in the leaves. In C. benghalensis, main constituents were 5-caffeoy.quinic acid and 4-caffeoy.quinic acid. Flavan-3-ols were described in all immature and mature pericarp and leaf extracts. Even though 4-feruloy.quinic acid was described in both immature and mature seed, dicaffeoy.quinic acids were identified only.in the mature seed extracts. Mangiferin was present in the leaf, mature pericarp and seed. Conclusions: These analy.es provide new chemotaxonomical data for the selected coffees, especially.for C. benghalensis. Due to its high poly.henol content, our results indicate its significance of providing new data as a possible source for industry.
