Abstract:Four compounds were isolated from the roots of Adenophora stricta. On the basis of spectrometric analysis and physicochemical constants, they were identified as β-sitosterol, β-sitostorolO-β-D-glucopyranoside, taraxerone and octacasanoic acid respectively. Taraxerone and octacasanoic acid were isolated from the plants of Adenophora for the first time.
