Arecaceae fruits are regarded as raw sources of valuable phytochemicals. In this work, several Arecaceae fruits
belonging to eleven taxa were screened for fatty acids (FA) by gas chromatography with flame ionization detector
and checked for their in vitro antitumor activity against the HT-29 colorectal cancer cells line through the
MTT test. The parallel use of two chromatography systems, HPLC-DAD and LC-MS, allowed the precise characterization
of all phenolic compounds contained in the fruits. Howea belmoreana had the highest FA amounts
(11.7 g/100 g on dry weight); Syagrus romanzoffiana had a relatively high PUFA content (26.3% of total FA); and
Butia capitata contains high amounts of medium-chain saturated FA (51.2%). Total phenolics reached 201.8 mg/
100 g on dry weight in Phoenix dactylifera var. Medjool. Among phenolics, occurred benzoic acids, phenylpropanoic
acid, and cinnamic acid derivatives. It highlights the great diversity of flavonoids detected as
