beta-Sitosterol (SI-0), beta-sitosterol glucoside (SI-1), dioscin (SI-2), methyl protoprosapogenin A of dioscin (SI-3), methyl protodioscin (SI-4) and protodioscin (SI-5) were isolated and characterized from the whole plant of Solanum indicum L. (Solanaceae). Except for beta-sitosterol, these
Ten compounds, including five steroidal saponins and five flavonol glycosides, were isolated from the whole plant of Solanum coagulans by means of column chromatographies over silica gel, ODS, Sephadex LH-20, and preparative HPLC. Based on analysis of MS and NMR spectroscopic data, their structures
A new characteristic steroidal glycoside of the 23S,26R-hydroxylated spirostanol-type named indioside F was isolated from the fruit of Solanum indicum, along with indioside A and protodioscin. On the basis of spectroscopic analysis, the structure of indioside F was found to be
A new spirostanol saponin (1), along with four known saponins, dioscin (2), protodioscin (3), methyl-protodioscin (4), and indioside D (5), and one known steroid glycoalkaloid solamargine (6) were isolated from the two synonymous species, Solanum incanum and S. heteracanthum. The structure of the
