Studies on the Steroidal Components of Domestic Plants. XVIII. Components of the Root of Bupleurum falcatum L. (2).

Abstract

α-Spinasterol had been isolated previously from the root of Bupleurum falcatum L. Its more-soluble sterol fractions were investigated by fractional crystallization and chromatography on alumina. Besides α-spinasterol three sterols, Δ⁷-stigmastenol, Δ²²-stigmastenol, and stigmasterol, were isolated and identified. Although Δ²²-Stigmastenol was already known as synthetic material, this work is the first example of its isolation from plants.
