    Project supported by the National Natural Science Foundation of China (Nos.81160391, 21166009 and 21162009), the 973 Research Program of the Ministry of Science and Technology of China (No.2011CB512010).

Eight clerodane-type compounds were isolated from the roots of Polyalthia laui and purified by silica gel column chromatorgraphy and preparative thin layer chromatorgraphy (TLC).Their structures were elucidated as polyalimide A (1),kolavenic acid (2), 2-oxo-kolavenic acid (3), 2-oxo-14,15-bisnor-3,11E-kolavadien-13-one (4), 3,4-dihydroxyclerodan-13E-en-15-oic acid (5), longimide B (6), 16-oxocleroda-3,13E-dien-15-oic acid (7), and solidagonal acid methyl ester (8).Compound 1 was a novel compound and compound 5 was isolated from this family for the first time, and all compounds were isolated for the first time from this plant material.Compounds 2 and 3 showed weakly inhibitory activities against SPC-A-1, SGC-7901 and K-562 human tumor cells.
