The limonoids of the seeds of Trichilia havanensis were studied in two ripening stages.From the unripened seeds azadirone, havanensin triacetate and three new limonoids were isolated.The mature seeds contained havanensin triacetate and its hydroxy lactone derivative.The structures of the new limonoids were deduced by spectroscopic and chemical means.

Tecleanin and 7-deacetylproceranone, two new tetranortriterpenoids from Teclea grandifolia Engl. (Rutaceae), have been assigned structures (2) and (4) respectively.Tecleanin has the same highly oxidised ring A as limonin but a carbocyclic ring D.A third new limonoid was indentified as 7-deacetylazadirone (13).
