Introduction: the Salvia coccinea L. species, known as banderilla, is used in Cuba as an ornamental plant. Nevertheless, some traditional medical uses have been reported in other countries without reports of pharmacological studies. No phytochemical study has been made with plants of this species growing in Cuba. Objective: to carry out the phytochemical study of hydroalcoholic extracts from stems, leaves and flowers of the Salvia coccinea L. species. Methods: stems, leaves and flowers were collected, washed, disinfected, dried at 40 °C and independently extracted under reflux with a EtOH/H₂O (60:40) mixture for 2 h at a solute-solvent ratio of 1:10. Results: compounds identified in both extracts were saponins, sugars, bitter principles, phenols, tannins, amino groups, alkaloids and flavonoids. The lyophilized extract from leaves and flowers contained 9.02 % of total polyphenols. Conclusions: several groups of compounds were found in the S. coccinea L. that grows in Cuba, such as flavonoids and alkaloids, and they could be of potential pharmacological interest. These results encouraged to continue the study of extracts from this plant and to begin evaluating their pharmacological effects.
