solamargine Usage And Synthesis
Description
First isolated from Solanum marginatum, this alkaloid has also been obtained from the ripe berries of S. khasianum var. chatterjeerum sengupta. It is laevorotatory with [α]20D - 105° (c 0.986, MeOH) and forms a picrate as yellow crystals, m.p. 188-9°C; picrolonate, m.p. 204-SoC and the benzoate with an indefinite melting point. Hydrolysis with 2N methanolic HCl furnishes solasodine, m.p. 197-8°C, one mole of D-glucose and two moles of L-rhamnose.
Uses
Solamargine is a natural steroidal glycoalkaloid produces a mild secondary effect through cortocoids produced in the adrenal glands.
