English. Phenolic compounds of the argan tree pulp were characterized. Their levels can be used to distinguish between four fruit forms: spherical, oval, oval-apiculated and spindle shaped fruits. The spindle shaped fruits are characterized by their higher phenolic content (7.2 mg/g fresh weight pulp (FW)) in comparison with the spherical and oval forms, containing 4.8 and 5.02 mg/g FW, respectively. The oval-apiculated form seems to be middle rich in phenolic compounds (5.8 mg/g FW). The analysis of phenolic extracts by UPLC showed a quantitative difference of some phenolic compounds, particularly (-)-epicatechin, others unidentified flavans and quercetin derivatives. A positive correlation between total phenol content and phenotypic characters was established

I loro livelli possono essere utilizzati per distinguere fra quattro forme del frutto: sferica, ovale, ovale-apiculata e fusiforme. I frutti fusiformi sono caratterizzati dal massimo contenuto di fenoli (7,1 mg/g di peso fresco della polpa (FW)) in confronto alle forme sferica e ovale, contenenti rispettivamente 4,8 e 5,02 mg/g di FW. La forma ovale-apiculata sembra presentare un contenuto intermedio di fenoli (5,8 mg/g di FW). L'analisi degli estratti fenolici effettuata mediante UPLC ha messo in evidenza differenze quantitative di alcuni fenoli, in particolare (-)-epicatechina, altri flavani e derivati della quercetina non identificati. E' stata stabilita uno correlazione positiva fra il contenuto di fenoli totali e i caratteri fenotipici]
