Isolation of β-Amyrin, α-Spinasterol and α-Spinasteryl Glucoside from the Roots of Solidago altissima L.

Abstract

The roots of Solidago altissima L. were extracted with hot methanol. The essential oil was removed from the methanol extract by steam distillation. The residue was extracted with ethyl acetate followed with ether.
The neutral fraction of the ether extract was chromatographed on an alumina column to give two crystalline compounds, which were identified as β-amyrin and α-spinasterol.
A crystalline compound, which was obtained from the ethylacetate extract by means of chromatography on a silica gel column, was identified as α-spinasteryl glucoside.
