Tamizaje fitoquímico de Scutellaria havanensis Jacq.

Introduccion: la especie Scutellaria havanensis Jacq., conocida como escudo de La Habana, es una planta endemica de Cuba, empleada para el tratamiento de la escabiosis, como diaforetico y febrifugo. Sin embargo, no se han realizado estudios fitoquimicos de esta planta. Objetivo: realizar un tamizaje fitoquimico de los extractos etereo, metanolico y acuoso de las partes aereas (hojas y tallos) de la especie Scutellaria havanensis Jacq. Metodos: se recolectaron las partes aereas frescas y se extrajeron con eter dietilico, metanol y agua. Los extractos se filtraron y se les realizaron las pruebas fitoquimicas de identificacion. Resultados: en el extracto etereo se identificaron alcaloides, coumarinas, triterpenos y esteroides; en los extractos acuoso y metanolico se encontraron alcaloides, grupos aminos, azucares, flavonoides, quinonas y resinas; mientras que en el extracto acuoso se detectaron saponinas y principios amargos. Conclusiones: Scutellaria havanensis, planta endemica cubana, contiene varios grupos de compuestos como flavonoides, alcaloides, entre otros, que pudieran tener interes farmacologico potencial. Estos resultados constituyen un apoyo para continuar los estudios fitoquimicos y farmacologicos de los diversos extractos 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
