Isolation and Identification of α-Spinasterol and α-Spinasteryl D-Glucoside from Sugar Beet Pulp

Abstract

α-Spinasterol and α-spinasteryl D-gluco-side were isolated from sugar beet pulp. The α-spinasteryl D-glucoside was hydro-lyzed, and each component was identified with α-spinasterol and D-glucose respec-tively. Infrared data showed that α-spina-sterol was identical with that isolated from spinach. α-Spinasteryl D-glucoside has been found for the first time in natue.
