THE STEROID CONSTITUENTS OF<i>PRUNUS MAHALEB</i>L. FRUIT KERNELS II¹

β–sitosterol was isolated from the nonsaponifiable matter of Prunus mahaleb L. kernel oil. It was also found in the defatted meal as β–sitosteryl–D–glucoside. β–sitosteryl acetate, bezoate and 3,5–dinitrobenzoate were prepared from the free β–sitosterol and from the β–sitosterol obtained from acid hydrolysis of the glucoside and were in good accordance with values reported. From the gluco–side a tetraacetate was prepared. Infrared and Ultraviolet spectra were made for the free β–sitosterol and for that obtained from hydrolysis and both were identical with that of authentic material. The sugar was identified by paper chromatography technique as glucose.
