Abstract This work investigates the content of feruloylquinic (FQA), caffeoylquinic (CQA) and dicaffeoylquinic (diCQA) acids in the peel, pulp and seed of 22 tropical fruits from Brazil. 3‐CQA, 4,5‐diCQA and 4‐ and 5‐FQA were not detected in any of the fruits analysed. Relatively small amounts of 4‐CQA (4.0–48.7 mg kg −1 ) were found in the peel and/or pulp of seven of the fruits; only the peel of Artocarpus heterophyllus was significantly ( p < 0.05) richer in this acid (1000 mg kg −1 ). The distribution of 3,4‐ and 3,5‐diCQA in different parts of the fruits was relatively poor, only reaching levels of up to 16.4 mg kg −1 . The peel of A heterophyllus also showed the highest amount of 5‐CQA (13 000 mg kg −1 ), while the seed of most fruits generally contained a lower amount of this acid than the peel or pulp. On the basis of the 5‐CQA content found in the pulp, 15 of the fruits were classified as follows: very low concentration (4.4–15.8 mg kg −1 ), low concentration (28.9–66.4 mg kg −1 ), medium concentration (132 mg kg −1 ), high concentration (473–474 mg kg −1 ) or very high concentration (1730 mg kg −1 ); however, no 5‐CQA was detected in the pulp of the other seven fruits. Thus 5‐CQA was the major chlorogenic acid present in most of the tropical fruits studied and was generally accompanied by small amounts of 4‐CQA and 3,4‐ and 3,5‐diCQA. © 2002 Society of Chemical Industry
