RODRIGUEZ LEYES, Eduardo A; GONZALEZ CANAVACIOLO, Víctor L  y  ADAMES FAJARDO, Yuliamny. Preliminary phytochemical composition of ripe fruits of Roystonea regia (Kunth) O.F. Cook. Rev Cubana Plant Med [online]. 2007, vol.12, n.4. ISSN 1028-4796.

This paper shows the results of preliminary phytochemical studies conducted in ripe fruits of Roystonea regia (Kunth) O.F. Cook. First, it was proved that 15 days were enough to guarantee the drying of the fruits in a well-ventilated place, at ambient temperature and protected from the direct exposure to the sun light. The results of the phytochemical screening demonstrated the presence of lipids, tripertenes and steroids, flavonoids, phenols and tannins, among others. It was determined that the extraction in Söxhlet with n-hexane, at a vegetal material-dissolvent ratio of 1:10 for 0.5 h, is an adequate method to calculate the lipid content of these fruits. These results will contribute to the phytochemical knowledge of this plant.
