Seven new lanostane-type triterpenoids, seco-coccinic acids A-F (1- 6) and coccinilactone A (7), were isolated from the roots of Kadsura coccinea. Their structures were established on the basis of spectroscopic data analysis. The absolute configuration at C-24 of compound 5 was confirmed by the modified Mosher's method. The cell growth inhibitory effects of these compounds were determined in human leukemia HL-60 cells, and it was found that compounds 1, 2, 3, and 5 exhibited antiproliferative effects with GI 50 values ranging from 6.8 to 42.1 microM.
