SOLASONINE C??? ??, ??, ??
??
This gly<:oalkaloid occurs in several species of Solanum including S. aviculare, S. sodomeum, S. verbascifolium and S. xanthocarpum. The alkaloid crystallizes from 80 per cent EtOH with 4.5 H20, m.p. 245-250°C (dec.), the anhydrous form being obtained from absolute MeOH. It has [α]25D - 68° (EtOH) and yields the following salts: hydrochloride, m.p. 265°C; picrate, m.p. 199-201 °C; picrolonate, m.p. 230-loC and the acetyl derivative, m.p. l35-8°C. On alkaline hydrolysis, the alkaloid gives solasodine and one mole each of galactose, glucose and rhamnose. The solution in concentrated H2S04 eventually gives a crimson colour with a brown fluorescence.??
α-Solasonine is a natural glycoalkaloid compound which has been shown to inhibit Gli-mediated transcritional activity.Purification Methods
Solasonine crystallises from aqueous 80% dioxane or MeOH in needles. [Bell & Briggs J Chem Soc 1 1942, Briggs et al. J Chem Soc 4645 1961, Briggs et al. J Chem Soc 2848 1963.] The picrate crystallises from 30% aqueous EtOH with m 197-198o(dec) [Briggs & Cambie J Chem Soc 1422 1958]. [Beilstein 27 III/IV 2006.]?? ??
