Serie D: Sciences Naturelles (Francia) v. 286(17) p. 1265-1267Summary: Five depsides exist within each of the floral parts of the five Eucoffea we have studied. Neochlorogenic, cryptochlorogenic and feruloyl-quinic acids always present lower amounts than chlorogenic and dicafeoylquinic depsides. This last "isochlorogenic" fraction predominates in the floral parts, except in the ovary, where the first rank goes to the chlorogenic acid. Moreover, for each depside, the amounts generally remain higher in that organ. This early setting of depsides and the predominance of the chlorogenic acid in the part of the flower that will give seeds, suggest for these compounds a role of stored substance. This role is confirmed by the high rates of depsides found in the beans
