RESUMO

Spondias mombin L. is a Brazilian tree belonging to the family Anacardiaceae and popularly known as “cajá”, the genus is well known by the various exotic fruit species such as “siriguela” (S. purpurea), “umbu” (S. tuberosa) and “umbu-cajá” (S. bahiensis). It presents commercial importance to the locals especially due the small juice fruit industries and the seeds are often discarded as waste after pulping. Despite the regional importance, even today there is little information on the chemical composition of these fruits. Thus, the dichloromethane extract of the waste seeds of S. mombin was subjected to different chromatographic fractionation allowing the isolation of a main triglyceride identified as 1,3-dioleoyl-2-linoleoyl glycerol, two new alkyl phenols named 1-hydroxyl-3-[(Z)-10’-octadecenyl]-benzene and 1-hydroxyl-3-[(Z)-10’-docosenyl] benzene, and a mixture of phytosteroids. The seed’s fatty acid profile and the cytotoxicity of the oils and isolated compounds were also determinated employing BST. The alkenylphenol mixture present some toxicity (CL50 215,4 µg mL-1) in this test.
