摘要：

The stem bark of Trichilia estipulata afforded three novel meliacin butenolides, 7 alpha-23-dihydroxy-3-oxo-24,25,26,27-tetranorapotirucall- 1,14,20(22)-trien-21,23-olide, 7-deacetyl-23-hydroxyneotrichilenonelide and 7-deacetyl-21-hydroxyneotrichilenonelide, which were identified on the basis of spectroscopic analyses. Scopoletin, isofraxidin, 7-oxo-24 beta-; 7-oxo-24 alpha-sitosterols and 3 beta-O-beta-D-glucopyranosylsitosterol were also isolated. The known compounds, velozonol, carnaubadiol, velozona, carnauba-21-ol-3-one, isofouqueriol, isofouquerinone, sitostenone and sitosterol were isolated from the leaves. (C) 1998 Elsevier Science Ltd.
