beta-Sitosterol Usage And Synthesis |
Chemical Properties | White powder |
Uses | A common sterol in plants. Isolated from wheat germ oil, corn oil. Antilipemic. Used in the treatment of prostatic adenoma. |
Uses | antiinflammatory, immunomodulator |
Definition | ChEBI: A phytosterols that is stigmast-5-ene substituted by a beta-hydroxy group at position 3. |
Purification Methods | Crystallise -sitosterol from EtOH, MeOH, Me2CO, Me2CO/EtOH or Me2CO/MeOH. It has also been purified by zone melting. The acetate crystallises from MeOH or EtOH as plates with m 127128o and [] D 20 -41o (c 2, CHCl3). The benzoate crystallises from EtOH as needles with m 146-147o and [] D 20 –13.8o (c 2, CHCl3).
