- A new triterpenoid saponin, 23-acetoxy,16α-hydroxy-13,28-epoxyolean-11-en-3β-yl-[β- d-glucopyranosyl-(1 → 2)]-[β- d-glucopyranosil(1 ←3)]-β- d-fucopyranoside, has been isolated from the roots of Bupleurum fruticosum, along with eight coumarins, scopoletin, scoparone, prenyletin, capensin, fraxetin, aesculetin,7-(3-methyl-2-butenyloxy-6-methoxycoumarin, 7-(2-hydroxy-3-methyl-3-butenyloxy)-6-methoxycoumarin and 5,7-dihydroxy-6-methoxy-8-(3-methyl-2-butenyl)coumarin. The last compound has not been previously encountered in nature. The structures were determined by analysis of NMR spectral data including two-dimensional techniques.
