Abstract
Fats or oils containing stigmasterol, especially soya bean oil or calabar bean oil, are subjected to short-path high-vacuum distillation whereby a distillate is obtained relatively concentrated in stigmasterol. The material may be saponified or partly saponified before distillation or as an intermediate step. A suitable temperature in the case of soya bean oil is 245 DEG C. Specifications 303,078, [Class 32], 415,088, and 438,056 are referred to.ALSO:Stigmasterol is concentrated by subjecting fats or oils containing it, especially soya bean oil or calabar bean oil, to short-path high-vacuum distillation whereby a distillate is obtained relatively concentrated in stigmasterol. The material may be saponified or partly saponified before distillation or as an intermediate step. A suitable temperature in the case of soya bean oil is 245 DEG C. The distillate may be redistilled and stigmasterol isolated by known methods. Specifications 303,078, [Class 32], 415,088, and 438,056, [Group III], are referred to.
