摘　　要：A diterpenoid trisaccharide, smithoside A, and a saponin, smithoside B, as well as six known compounds, apigenin, apigenin-7-O-glucoside, daucosterol, shanzhiside methyl ester, 8-acetylshanzhiside methyl ester and acteoside, were isolated from Aster smithianus. On the basis of spectral evidence and chemical analytical results, smithosides A and B were identified as pimar-1 5 （ 16 ） -β-ene-8β, 11 α-diol-3β-O-β-D-glucopyranosyl （ 1→3 ） - [ β-glucopyranosyl（ 1 →2 ） ] -β-D-glucopyranoside and 2β,3β, 16β,21β,23-pentahydroxy-12-ene-28 oleanoic acid lactone-3-O-β-D- glucopyranosyl （ 1→3 ） -β-D-glucopyranoside, respectively.A diterpenoid trisaccharide, smithoside A, and a saponin, smithoside B, as well as six known compounds, apigenin, apigenin-7-O-glucoside, daucosterol, shanzhiside methyl ester, 8-acetylshanzhiside methyl ester and acteoside, were isolated from Aster smithianus.
