Two diterpenes were isolated from the leaves of Xylopia langsdorffiana, the new ent-atisane- 7α,16α-diol named xylodiol (1) and the known 8 (17),12E,14-labdatrien-18-oic acid (2). The structures of these isolates were deduced by spectroscopic data

The volatile fraction of Xylopia langsdorffiana leaves was analyzed by GC and GC/M S and tested for molluscicidal activity. With this methodology 19 different components were identified in the oil. Among them, germacrene D (22.9%), trans-β-guaiene (

Two new diterpenes of the ent-trachylobane type were isolated from the stems of Xylopia langsdorffiana, ent-7alpha-acetoxytrachyloban-18-oic acid (1) and ent-7alpha-hydroxytrachyloban-18-oic acid (2). The structures of these isolates were deduced by
