摘要：

The fruits of palm trees (Arecaceae) are a very important food source for fauna and for humans, despite the still incipient role of these fruits in conventional diet. Seven palm tree species (plus one variety) that are native to the southern half of South America located east of the Andes (Argentina, Paraguay, Uruguay, and the southern states of Brazil) were studied. For the first time, the fatty acid profiles of palm seeds and the content of both amino acids and phenolic compounds present in the pulp (yellowish fleshy mesocarps) of the fruits were determined. High-performance liquid chromatography coupled to tandem mass spectrometry (HPLC-MS/MS) was used to screen and quantify thirty-two phenols and HPLC was used to determine the amino acid contents and fatty acids profiles of the species. Twenty-five percent of the fatty acids in the seeds of B. lallemantii, Butia odorata (var. pulposa), B. witeckii, and Syagrus romanzoffiana were found to be unsaturated. One species (B. lallemantii) had a high and well-balanced amino acid content (28,900 mg/kg), while six species (B. odorata, B. catarinensis, B. witeckii, Euterpe edulis, and Syagrus romanzoffiana) contained more than 14,000 mg/kg of amino acids. A high content of the phenolic compounds ferulic acid, luteolin, quercetin-3-rutinoside, isoquercetin, and isorhamnetin were found in many species, most notably in B. odorata, B. catarinensis, and B. witeckii.
