A new aromadendrane sesquiterpene, allo-aromadendrane-10alpha, 14-diol (3), was isolated from Chisocheton penduliflorus (Meliaceae), along with two known sesquiterpenes: allo-aromadendrane-10beta, 14-diol (2) and allo-aromadendrane-10beta, 13, 14-triol (7). Six dammarane triterpenoids, including cabraleadiol (1), eichlerialactone (4), cabraleahydroxylactone (5), cabralealactone (6), hollongdione (8) and dammaradienone (9), the coumarins scoparone and scopoletin, and vanillic acid were also isolated from the wood and leaves of this plant. Compounds 1-7 displayed antimycobacterial activity against Mycobacterium tuberculosis. Compounds 1, 4, 5 and 6 were weakly cytotoxic to a breast cancer (BC) cell line; whereas, compound 6 was moderately active against a small-cell lung cancer (NCI-H187) cell line.
