“…The larger amount of lipid extracted from babassu nuts by Soxhlet extraction with hexane (method A) in contrast with petroleum ether (method B) was due to a better solubility of non-polar lipids in hexane. 18,19 Therefore, the extraction method A was the most appropriate methodology for obtainment of triacylglycerols from babassu nuts.The lipid fraction extracted using method A was subjected to hydrolysis reaction to free fatty acids (FFA). Then, FFA was submitted to esterification reaction using H 2 SO 4 /NH 4 Cl/methanol resulting in their respective fatty acid methyl esters.…”

A composição de ácidos graxos de seis amostras de Orbignya phalerata de diferentes cidades do estado do Maranhão foi estudada. Os óleos foram extraídos utilizando extrator Soxhlet por duas metodologias e a composição de ácidos graxos foi avaliada por cromatografia gasosa-espectrometria de massas (CG-EM). O teor da fração de lipídios revelou que o solvente usado influencia na extração, sendo a maior porcentagem obtida com hexano. O teor de lipídios variou de 62,46-67,45%, com predominância de ácidos graxos saturados (80,32-87,80%), principalmente ácido láurico (C12:0) com percentual de 44,86-52,15%. A análise multivariada mostrou a distribuição das amostras de O. phalerata em três regiões distintas e sugere que a composição química dos óleos pode estar associada com a sua localização geográfica. Estes dados mostram o conhecimento da biodiversidade de ácidos graxos de O. phalerata entre as diferentes regiões do estado do Maranhão.The fatty acid composition of six Orbignya phalerata samples of different cities from Maranhão State (Brazil) was studied. The oils were extracted by two methods using Soxhlet extractor and the fatty acid composition was evaluated by gas chromatography-mass spectrometry (GC-MS) analysis. The lipid fraction content showed that the solvent used influences lipid extraction, the highest percent was obtained with hexane. Lipid content ranged from 62.46-67.45%, with predominance of saturated fatty acids (80.32-87.80%), mainly lauric acid (C12:0) with 44.86 to 52.15%. Multivariate analysis showed the distribution of O. phalerata samples into three distinct regions and suggests that the oil chemical composition may be associated with their geographic location. These data show knowledge of the biodiversity of O. phalerata fatty acids among the different regions of the Maranhão State (Brazil). The babassu fruits are oval and elongated weighing 90-280 g. The fruit contains epicarp (11% in mass), mesocarp (23% in mass) and endocarp (59% in mass) with 3-4 nuts (7% in mass), which are rich in triacylglycerols (> 60% in mass), with predominance of lauric acid (C12:0) and minerals (Al, Ba, Ca, Cu, Fe, K, Mg, Mn, Sr and Zn). 2,3 The babassu nut is one of the non-timber products that stood out the most out in production value, concentrating the total of extractive production in the Brazilian Northeast (99.4%), making the Maranhão State the largest producer of babassu nuts, corresponding to 54.6% of national output in 2010. 4 According to the Brazilian Agricultural Research Corporation (EMBRAPA), 5 the economic potential of babassu fruits, especially its nuts, as well as its oil, is largely used in pharmaceuticals, cosmetics, food and medicinal uses. Souza et al. 6 reported that in the traditional medicine of Northeast Brazil, babassu-derived products are mainly used in some diseases, such as inflammation process. Although, babassu oil presents several industrial applications, for example biodiesel production, 7 the chemical knowledge is necessary to ensure quality and better exploitation of biomass. Keywo...

“…Previous studies reported percentage lipid contents of Pisum seeds ranging from 0.9% to 5.0% [3]. Compared to soybean and canola (14.0% and 41.0%, respectively) such low lipid contents would require effective breeding programs to develop field peas as a competitive oil source.…”

“…Having determined the diversity of the 35 pea accessions and the informativeness of the SSR markers, we next looked to identify marker-trait associations that may further facilitate the process of developing an oilseed pea. Lipid content estimations in the Pisum seeds for its use in marker-trait associations were obtained from Khodapanahi et al [3]. This study is among the first to perform marker-trait associations in field pea.…”

Field pea (Pisum sativum L.) is an important protein-rich pulse crop produced globally. Increasing the lipid content of Pisum seeds through conventional and contemporary molecular breeding tools may bring added value to the crop. However, knowledge about genetic diversity and lipid content in field pea is limited. An understanding of genetic diversity and population structure in diverse germplasm is important and a prerequisite for genetic dissection of complex characteristics and marker-trait associations. Fifty polymorphic microsatellite markers detecting a total of 207 alleles were used to obtain information on genetic diversity, population structure and marker-trait associations. Cluster analysis was performed using UPGMA to construct a dendrogram from a pairwise similarity matrix. Pea genotypes were divided into five major clusters. A model-based population structure analysis divided the pea accessions into four groups. Percentage lipid content in 35 diverse pea accessions was used to find potential associations with the SSR markers. Markers AD73, D21, and AA5 were significantly associated with lipid content using a mixed linear model (MLM) taking population structure (Q) and relative kinship (K) into account. The results of this preliminary study suggested that the population could be used for marker-trait association mapping studies.

“…China, with 1.3 million ha sown, is a major producer of peas for green pods/seed (FAOSTAT 2012). Although pea is currently recognized as a protein crop (20-25%), its potential is also as a source of high-quality starch (up to 50%) and even putatively as an oil (1-5%) source (Khodapanahi et al, 2012). The key breeding objectives involve increasing yield potential by improving biotic and abiotic stress resistances and enhancing quality for diverse food markets.…”
