Abstract:

This investigation was conducted as part of a continuing effort to develop a database on the chemistry of tree seeds. Seeds of Vochysia hondurensis Sprague were collected from three mature trees vigorously growing in a wet site, 400 m above sea level in San Ramon de la Virgen, Sarapiqui, Costa Rica. These were analyzed for starch, reducing and nonreducing sugars, total N (protein), amino N, total lipid, and fatty acids. The seeds contained high concentrations of lipids (28.6%) and protein (34%), but extremely low concentrations of carbohydrates (4.21%). Although 11 fatty acids were detected, three (oleic, arachidic, and cis-11-eicosenoic) comprised 80% of the total fatty acid weight. Based on these chemical contents, V. hondurensis seeds appear to exhibit orthodox behavior. For. Sci. 37(3):949-952.
