英文摘要: Two new triterpenoids, 3 beta, 15 alpha, 21 beta, 23-tetrahydroxy-12-oleanen-28-oic acid (1), 3 beta, 6 alpha, 21 beta, 23-tetrahydroxy-12-oleanen-28-oic acid (2), together with seven known compounds, viz., paeonol (3), 3, 4-dihydroxybenzoic acid (4), scosoletin (5), anthraquinones chrysophanol (6), 4H-1-benzopyran-4-one, 5, 7-dihydroxy-2-methyl (7), beta-sitosterol (8) and stigmasterol glucoside (9) were isolated by the chromatography of the silica gel, RP-18 and Sephadex-LH 20 from the EtOAc extract of Neonauclea sessilifolia (Roxb.) Merr. (Rubiaceae). Their structures were elucidated based on spectral analysis including 1D-, 2D-NMR (HMQC, HMBC), IR and EIMS. Among them, compound 6 was shown to possess inhibitory activity on the growth of Mycobacterium tuberculosis (Zopf) Lehmann et Neumann with a minimum inhibitory amount of 25 mug, compounds 2 and 4 also showed weak inhibitory activities on the growteof M. tuberculosis.
