【 摘 要 】
This paper describes the morphological and anatomical aspects and the essential oil analysis of the leaves from Hennecartia omphalandra J. Poisson (Monimiaceae), a toxic plant. The presence of trichomes formed by a single cell, paracitic stomata, groups of braquisclereids in the petiole and leaf blade; vermiform and ramiform sclereids, vascular system in arc softly invaginated at ends in the petiole, and in a flat arc in the middle vein, being the venation pattern a variation of craspedodromous-semicraspedodromous type, and essential oil stored in oil idioblasts in the mesophyll were the most important characters that can help the morphological diagnosis. The analysis of essential oil of the leaves showed the presence of monoterpenes, as well as sesquiterpenes hydrocarbons and alcohols, being the latter the most significant group. The major identified compounds were β-phelandrene (24.0%), germacrene D (10.5%), sabinene (9.3%), bicyclogermacrene (8.4%) and β-elemene (5.3%).
