“…The most abundant one was linoleic acid, representing 39.8, 47.3 and 61.2 % of the fatty acid composition of H. parviflora, H. tomentosa and P. pendula, respectively. Linoleic acid contents of B. excelsa and H. parviflora, however, are slightly lower than those previously reported (Assunção et al, 1984;Lago et al 1987). Fatty acid composition of the Parkia seeds is in agreement with the results of Lago et al (1987).…”

“…According to Carbonaro et al (2000), plant seeds represent a major source of dietary proteins, with amounts varying from 10 % (dry mass) in cereals to around 40 % in certain legumes and oilseeds. The oil content observed in P. pendula seeds (28.4 %) was three times greater than values reported by Lago et al (1987) for two other Parkia species which also occur in the Brazilian Amazon. When compared to the oil content of African species, P. pendula was similar to that observed by Gunstone et al (1972) for P. roxburghii (20 % oil).…”

“…Palmitic acid (C 16:0 ) was the main saturated fatty acid identified, whereas oleic (C 18:1 ) and linoleic (C 18:2 ) were the most representative unsaturated fatty acids. Large amounts of unsaturated fatty acids have been observed in many species from the Brazilian Amazon (Lago et al, 1987). In this study, P. pendula seeds contained approximately 71.1 % of unsaturated fatty acids, 61.2 % of which correspond to linoleic acid (table 2).…”

“…It is possible that the production of fatty acids is limited to their biosynthesis of up to 18 carbons. Arachidic and behenic acids appear to accumulate in several species of the Parkia genus (Lago et al, 1987;Aiyelaagbe et al, 1996). B. excelsa storage tissue had significantly greater P, Mg and Zn contents than A. parviflora and H. parviflora storage tissues (table 3), whereas P. pendula had significantly more K and Cu than A. parviflora, B. excelsa and H. parviflora.…”

The contents of the main components of the primary metabolism (soluble sugars, starch, proteins, oils, fatty acids) and minerals (P, Ca, Mg, K, Fe, Zn, Mn, Cu) were characterized in seeds of five Brazilian Amazon tree species (Andira parviflora, Bertholletia excelsa, Helicostylis tomentosa, Hymenaea parviflora, and Parkia pendula). Soluble sugar contents were high in P. pendula seeds (14 %), whereas starch predominated in A. parviflora seeds (58.7 %). A. parviflora and H. parviflora seeds were rich in proteins (35.1 % and 32.4 %, respectively). The oil contents ranged from 1.4 % in A. parviflora to 70.7 % in B. excelsa. Only B. excelsa and P. pendula seeds may be considered oilseeds, with 70.7 % and 28.4 % oil, respectively. The fatty acid compositions showed high proportions of unsaturated fatty acids, mainly oleic and linoleic acids, regardless of the species. B. excelsa and P. pendula also showed high amounts of P, Mg, K and Zn.Key words: Fatty acids, minerals, oils, proteins, soluble sugars, starch.Componentes do metabolismo primário de sementes de espécies arbóreas da Amazônia brasileira: Os conteúdos dos principais componentes do metabolismo primário (açúcares solúveis, amido, proteínas, óleos, ácidos graxos) e de minerais (P, Ca, Mg, K, Fe, Zn, Mn, Cu) foram caracterizados em sementes de cinco espécies arbóreas da Amazônia Brasileira (A. parviflora, B. excelsa, H. tomentosa, H. parviflora e P. pendula). O conteúdo de açúcares solúveis foi maior em P. pendula (14 %) e o de amido predominou em sementes de A. parviflora (58,7 %). Sementes de A. parviflora (35.1 %) e H. parviflora (32.4 %) mostraram-se ricas em proteínas. O conteúdo de óleo variou de 1,4 % em A. parviflora a 70,7 % em B. excelsa. Sementes de P. pendula têm 28,4 % de óleo e junto com sementes de B. excelsa, podem ser consideradas como sementes oleaginosas. Independente da espécie, a composição de ácidos graxos mostrou maior proporção de ácidos graxos insaturados, principalmente ácidos oléico e linoléico. B. excelsa e P. pendula também apresentaram maiores quantidades de P, Mg, K e Zn.

The CI‐(CH4) mass spectra of the methyl esters and the EI mass spectra of the oxazoline derivatives of three cyclopropenoid fatty acids (malvalic, sterculic and α‐ hydroxy‐sterculic acid) from the seed oil ofPachira aquatica were found to be useful for structure elucidation of such compounds. Furthermore, some hitherto unknown minor fatty acids were identified and the nuclear magnetic resonance data of the oil and α‐hydroxysterculic acid methyl ester are presented.
