The Phellodendron sterol (sterol mixture), obtained from the unsaponifiable matter of Phellodendron amurense RUPR. (family Rutaceae), was derived to its acetate, purified by alumina chromatography, and fractionally recrystallized from ethanol into β-sitosterol and γ-sitosterol. Ultraviolet absorption spectrum of the phellodendron sterol indicated the presence of Δ5, 7-sterol in approx. 0.5%.
