Studies on the physico-chemical properties of acetone-solubles from Torreya nucifera seeds, the composition, and chemical structure of desmethylsterol from the lipids are summarized as follows; 1. The acetone-soluble lipids and moisture content of Torreya nucifera seeds amounted to 46.6% and 9.3%, respectively. 2. The unsaponifiable content, iodine value, and saponification value of the lipids were 0.3%, 122 and 189.3, respectively. 3. The desmethylsterols comprised three components, whose Rrts (1.5% OV-17 to
