摘要

Three new diterpenoids,including two halimanes,5(10),13E-halimadiene-3α,15-diol(1),and 5(10),14-halimadiene-3α,13ξ-diol(2),one labdane,12-(3-methyl-furan)-labd-8(17)-en-19-oic acid(3),together with sixteen known compounds were isolated from the barks of Dysoxylum densiflorum.All compounds were elucidated by extensive spectroscopic analysis.
