title: Triterpenoids and Sesquiterpenes from Mulgedium tataricum.
abstract: The chemical investigation of Mulgedium tataricum afforded six new compounds which were identified as lanost-9(11),23 Z(24)-diene-3beta,25-diol (1), lanost-9(11),25-diene-3beta,24beta-diol (2), ursane-20-ene-3beta,22alpha-diol (3), 4 E,10 E-3beta,11beta-dihydroxygermacra-4(5),10(1)-dien-12,6alpha-olide (4), 4 E-1beta-hydroperoxy-3beta,11beta-dihydroxygermacra-4(5),10(14)-dien-12,6alpha-olide (5) and lactucin-8-O-P-methoxyphenyl acetate (6) by using a combination of MS and NMR techniques. Compound 6 exhibited significant cytotoxicity against cultured human hepatoma cells (SMMC-7721) and human acute promyelocytic leukemia cells (HL60). The antibacterial activity study indicated that 1 and 2 strongly inhibited the growth of Escherichia coli.
