From the dichloromethane–methanol (1:1) extract of the seeds of Turraeanthus mannii (Meliaceae), a new bis-labdane diterpenoid, namely (–)-15′,16′-dihydroxy-15(12′),15′(16′)-diolide-bislabda-8(17),8′(17′),12-trien-16-al, trivially named ent-turrealabdane (1), has been isolated together with six already known secondary metabolites: scopoletin, isoscopoletin, 6-hydroxy-7,8-dimethoxycoumarin, 3-methylhydantoin, β-sitosterol, and β-sitosterol 3-O-β-D-glucopyranoside. Esterification of ent-turrealabdane (1) using benzoyl chloride yielded a dibenzoyl derivative 2. The structures of these compounds were established by spectroscopic analysis including 1D and 2D NMR experiments in combination with MS.
