MARTINEZ-ECHEVARRIA, María T. et al. Phytochemical analysis of the fruit extracts of the Cordia collococca species. cultrop [online]. 2017, vol.38, n.2, pp. 07-14. ISSN 1819-4087.

There are endemic species exist in the Pinar del Rio municipality, Cuba. That in one season of the year birds and pigs take advantage of their fruits for their feeding. They are developed in different ecosystems, presenting different characteristic in the period of fructification. Among these species the Cordia collococca is used for the farmers to feed hens and pigs. It was carried out the gathering of their fruits, in "El avioncito" locality later pulping and watery and alcoholic extracts were prepared, used to carry out rehearsals of sifting phytochemical in function of determinate the presence of secondary metabolites. It was weighed 5 grams of the sample, they were added 50 mL of alcohol and reflowed. They were identified in abundance alkaloids, reducers’ compounds, free aminoacids, flavonoids and mucilage and japonicas in smaller proportion. Also they were carried out acceptability rehearsals of the foods in substitution birds of 34 days. The period of adaptation began with the observation method during four weeks. The acceptability tests allowed evaluate in a short time the preference of the food, providing fast and sharp results. In the conclusions we realize that present active principles in the extracts show a low toxicity, what allows contining their development for their evaluation like a conventional alimentary alternative
