Investigation of Hemolytic and Spasmolytic Activities of the Total Alkaloid Fraction from Root Bark of Solanum paludosum Moric. (Solanaceae)

摘要

The Solanaceae family is distributed worldwide with approximately 106 genera and 2300 species (Olmstead et al. 1999). The Solanum genus is considered one of the largest among angiosperms with about 1700 species (Hunziker 2001). It is a rich source ofsecondary metabolites. Many species of Solanum are popularly known in Brazil as 'jurubeba.' Plants of this genus are known to produce a great variety of steroidal saponins and glycoalkaloids that play an important role in natural resistance against several pests (Friedman et al. 1991).
