摘要： Four new triterpenoid saponins, Catunaroside E (1; 3-O-{β-D-glucopyranosyl-(1→2)-[β-D-glucopyranosyl-(l→3)]-β-D-glucopyranosyl}-siaresinolic acid), Catunaroside F (2; 3-O-{α-L-rhamnopyranosyl-(l→2)-[β-D-glucopyranosyl-(l→3)]-β-D-glucopyranosyl}-28-O-β-D-glucopyranosyl)-oleanolic acid), Catunaroside G (3; 3-0-[α-L-rhamnopyranosyl-(l→2)-β-D-glucopyranosyl]- 28-O-β-D-glucopyranosyl)-siaresinolic acid), and Catunaroside H (4; 3-0-{β-D-glucopyranosyl-(l→2)-[β-D-glucopyranosyl-(1→3)]-β-D-glucopyranosyl}-28-O-(β-D-glucopyranosyl)-siaresinolic acid), and the known triterpenoid saponin Mussaendoside J (5), were isolated from the stem bark of Catunaregam spinosa. Their structures were elucidated on the basis of their spectral data and chemical evidence.
