摘要：

Chemical examination of the ethyl acetate solubles of the CH3OH:CH2Cl2 (1:1) extract of the roots of Excoecaria agallocha L. collected from Godavary estuary resulted in the isolation of three more new diterpenoids, agallochins M-O (1-3). The structures of the new diterpenoids were elucidated by a study of their physical and spectral data as methyl ent-13-epi-8, 13-epoxy-4,6alpha-dihydroxy-3,4-secolabd-14-en-3-oate (1), methyl ent-13-epi-8,13-epoxy-2,3-secolabd-14-en-2,11-olid-3-oate (2), and methyl ent-17-hydroxy-3,4-secokaura-4(19),15-dien-3-oate (3).
