[Steroidal saponins and their pharmacological activities in Solanum plants]

The genus Solanum which is the largest genus in Solanaceae consists of more than 2 000 species, most of them are distributed in tropics and subtropics areas, and only a small amount in temperate regions throughout the world. Steroidal saponins could be found in many species of the Solanum, and they are an important group of natural products exhbiting a number of potent beneficent properties, such as anti-tumor, antibacterial, antifungal, anti-inflammatory, antiviral, antioxidant, hypoglycemic, and antihyperlipidemic effects. As supplement, this paper gives a review of different structural categories of steroidal saponins and their pharmacological effects from the solanum plants over the past decade, and it is intended to provide a point of reference for further research on steroidal saponins in Solanum plants.
