“…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). In this study, the H. parviflora oil content (8.2 %) was twice as high as the values observed for the same species in Singapore (Cornelius et al, 1970). Unsaturated fatty acids predominated over saturated acids (table 2), with high contents being observed in B. excelsa, A. parviflora and P. pendula seeds (75.2 and 74.2 % and 71.1 %, respectively).…”

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.

“…While one report [11] does not even mention cyclopropene or cyclopropane fatty acids, another report indicates 2.5% malvalic and 1.6% sterculic acid with 0.9% combined dihydrosterculic acid/C18:3v3 [12] while another [3] reports up to 8% cyclopropenoid acids (given as sterculic acid). The fatty acid profile of Thespesia populnea oil as obtained here is given in Table 1 and shows malvalic acid at approximately 7% (6.8% as determined by GC).…”

“…Thespesia populnea belongs to the Malvaceae family and, accordingly, its seed oil is known to contain cyclopropane and cyclopropene fatty acids [5,6,10]. Both malvalic acid and sterculic acid (9,10-methylene-9-octadecenoic acid) as well as dihydrosterculic acid (9,10-methylene octadecanoic acid) have been reported in Thespesia populnea [10], while an earlier report [11] does not mention the presence of cyclic fatty acids and another gives them combined as sterculic acid [3].…”

Thespesia populnea belongs to the plant family of Malvaceae which contain cyclopropane and cyclopropene fatty acids. However, previous literature reports vary regarding the content of these compounds in Thespesia populnea seed oil. In this work, the content of malvalic acid (8,9-methylene-9-heptadecenoic acid) in the fatty acid profile of Thespesia populnea seed oil was approximately 7% by GC. Two cyclopropane fatty acids were identified, including dihydrosterculic acid. The methyl and picolinyl esters of Thespesia populnea seed oil were also prepared. The mass spectrum of picolinyl malvalate was more closely investigated, especially an ion at m/e 279, which does not fit the typical series of ions observed in picolinyl esters. It is shown that this ion is caused by cleavage at the picolinyl moiety and contains the fatty acid chain without the picolinyl moiety. This type of cleavage has previously not been observed prominently in picolinyl esters and may therefore be diagnostic for picolinyl esters of cyclopropene fatty acids. The NMR spectra of Thespesia populnea methyl esters are also discussed. Practical applications:The work reports the fatty acid composition of Thespesia seed oil whose derivatives have not yet been extensively utilized for industrial purposes, for example, biodiesel. Knowing this composition is essential for understanding potential uses and, for example, in case of biodiesel the fuel properties. Besides this issue, some data (mass spectrometry and NMR) crucial for obtaining the composition information are analyzed in detail. The biodiesel properties of methyl esters of Thespesia populnea will be reported separately.

“…Cyclopropenoid fatty acids (CPEFA) are known to occur in Sterculia species (3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13), and their biological effects on animals (14-16) have been the subject of a number of investigations including cocarcinogenic (17)(18)(19) and carcinogenic activity (20). S. tomentosa and S. tragacantha seed oils, which are used by the local population, have not been studied although ten oils from various Sterculia species have been investigated for their CPEFA content (3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13).…”

Seed oils ofSterculia tomentosa andS. tragacantha (Sterculiaceae) were found to contain malvalic (5.8 and 5.1%), sterculic (11.3 and 30.2%) and dihydrosterculic (0.9 and 0.5%) acids. The total amount of these two cyclopropenoid fatty acids was established by1H nuclear magnetic resonance and their cooccurrence by gas chromatography. Besides these unusual compounds, the main common fatty acids were palmitic (20 and 24%), oleic (21 and 15%) and linoleic (30 and 16%) acids.
