【Abstract】 A new sesquiterpenoid glycoside was isolated from aerial parts of Saussurea involucrata. et Kin. Cellulase hydrolysis of this compound gave a new guaia-nolide, named as involucratolactone, G15H20O3, m,p. 134-135℃, [α]D24 + l5, (C=0.17 CH3OH). The structure of involucratolactone-8-β-D-glucoside elucidated on the basis of UV, IR, MS, 1H NMR, 13G NMR spectral analysis and some chemical transformations.更多还原
