Abstract: | The Δ7-and Δ5-sterol fractions were isolated from the unsaponifiable matter of ripe, air dried, chestnut seed. The Δ7-sterol fraction amounted to 18.4% and the Δ5-sterol fraction amounted to 8.2% of the unsaponifiable matter. In the Δ7-sterol fraction three components were identified as Δ7-campesterol, α-spinasterol and Δ7-stigmastenol. One component was probably Δ5,7-stigmastadienol and five components remained unidentified. Δ7-stigmastenol and α- spinasterol were the major components and amounted to 74.8% of the fraction. In the Δ5-sterol fraction at least ten components were found. Five of them were identified as cholesterol, campesterol, stigmasterol, sitosterol and Δ4-stigmasten-3-one. Stigmasterol and sitosterol amounted to 73.6% of the fraction. |
