MARRERO DELANGE, David et al. Phytochemical screening of Scutellaria havanensis Jacq.. Rev Cubana Plant Med [online]. 2012, vol.17, n.4, pp. 402-407. ISSN 1028-4796.

Introduction: Scutellaria havanensis Jacq. species, known as Escudo de La Habana (Havana skullcap), is an endemic Cuban plant, etnomedically used for the treatment of scabies and as a diaphoretic and a febrifuge. However, no phytochemical study of this plant has been made so far. Objective: to conduct a phytochemical study of the ethereal, methanol and aqueous extracts from aerial parts (leaves and stems) of Scutellaria havanensis Jacq. species. Methods: fresh aerial parts were harvested and extracts were obtained with diethyl ether, methanol and water. The extracts were filtered and subjected to the phytochemical identification tests. Results: alkaloids, coumarins, triterpenes and steroids were identified in the ethereal extracts, whereas alkaloids, amino groups, sugars, flavonoids, quinones and resins were found in the methanol and aqueous extracts, and saponins and bitter principles in the aqueous extract. Conclusions: Scutellaria havanensis, an endemic Cuban plant, contains several groups of compounds of potential pharmacological interest like flavonoids and alkaloids, among others. These results encourage continuing the phytochemical and pharmacological studies of several extracts.
