| Abstract: | To develop a process for the separation of stigmasterol from phytosterol mixture by chemical derivatization and solvent crystallization. Its performance procedure, including acetylation, bromization, debromination, and saponification of phytosterol mixture, and crystallization with solvent, was used at the gramme level on a test bench. The yield of stigmasterol is 6.9% and the recovery rate is 45.7%. The phytosterol mixture was separated by the method. This illustrate that the method was feasible and suitable for a pilot run. |
