“…Regarding Soxhlet extraction, the main components were oleic and linoleic acids with average percentages of around 42.0% and 39.0%, respectively (Table 2). Those results are similar to the ones previously reported by Elleuch et al (2007) and Corso et al (2010), who obtained a profile of fatty acids with predominantly linoleic (43-46.8%) and oleic (35-36.4%) acids by the same extraction technique. According to Table 2, considerable differences can be observed in the composition of the sesame oil obtained by Soxhlet extraction.…”

“…Corso et al (2010) obtained yields of 52.6% for a 20 hour extraction process. Elleuch et al (2007) obtained a lower yield, 41.46% over 4 hours, using raw material from Sudan. These results, when compared to those found in this study (58.93% using ethanol as a solvent and 47.54% for petroleum ether), indicate that ethanol may be a more appropriate solvent for solubilizing sesame extracts, since its use resulted in a considerable yield increase with both extraction techniques studied.…”

-This article carried out the extraction of sesame oil by using three extraction techniques: supercritical fluid extraction (SFE), Soxhlet and sequential extraction. The SFE was performed using supercritical carbon dioxide (SC-CO 2 ) as solvent and ethanol as cosolvent. Tests were performed at 20 MPa, 35°C and a flow rate of 2.5 g CO 2 /min with a total extraction time of 210 minutes. The Soxhlet extraction was performed for 8 hours, using petroleum ether and ethanol as solvents, until the exhaustion of the oil contained in the seeds. The sequential extraction used ethyl ether, ethanol and water as solvents. The Soxhlet extraction was the most effective (58.93%), while the SFE technique obtained 26.47% as the best result. The antioxidant activity (AA) was determined by the β-carotene/linoleic acid system, with good oxidation inhibition percentages (29.32-83.49%) for all the extracts. The main fatty acids (FA) in sesame oil were oleic and linoleic acids.

“…A key feature of legumes as a resource for phytoremediation is their role in providing additional N-compounds to the soil, thus improving soil fertility and ability to support biological growth (Xiuli et al, 2013;Hao et al, 2014). On the other hand, sesame (Sesamum indicum L.) is an economically important oil seed crop of family Pedaliaceae, planted in arid and semi-arid regions of the world (Elleuch, Besbes, Roiseux, Blecker, & Attia, 2007) including Pakistan, used as an alternative feedstock for the production of a biodiesel fuel (Saydut, Duz, Kaya, Kafadar, & Hamamci, 2008). The methyl ester extracted from sesame seeds can effectively be utilized as petrodiesel (Ahmad et al, 2011).…”

Contamination of lead indicates one of the major threats to soil system. Phytoremediation technique utilized plants which are able to tolerate and accumulate metals within in their tissues. It has recently been suggested that biofuel plants are more suitable for both utilization and remediation of metal contaminated soil. This study reported Pb phytoremediation potential of Cyamopsis tetragonoloba L. in comparison with Sesamum indicum L. in the framework of a pot-experiment. Plants were subjected to seven Pb concentrations (0, 100, 200, 400, 600, 800 and 1000 mg kg -1 soil) for 12 weeks. Our results demonstrated that both C. tetragonoloba and S. indicum were able to tolerate Pb concentrations up to 1000 mg kg -1 which confirms the plant ability to grow well in higher Pb levels. Significant metal accumulation was observed in root along with reduced biomass for both plants species. Furthermore, both plant species could possibly be used for phytostabilization, with success in marginally polluted soils where their growth would not be impaired and decontamination of Pb could be maintained at satisfying levels. However, bioconcentration factor (BCF), bioaccumulation coefficient (BAC) and translocation factor (TF) values proposed that C. tetragonoloba was more efficient for phytoremediation than S. indicum at higher Pb levels.

Effect of cultivation conditions on the composition of sesame seed and oilFourteen selected sesame genotypes were grown in Patos, Paraíba State, Brazil and Barbalha, Ceará State, Brazil, and the trials were at a randomized block design with five replicates under non-irrigated and irrigated conditions, respectively. Seeds were evaluated for oil yield and chemical composition, while defatted meal was analyzed for amino acids content. The fatty acids and sterols profiles were also evaluated, as well as the characteristics for identity and oil quality. The differences observed between genotypes in the same area were small. However, significant differences (p <0.05) between the areas for oil content and protein were observed, with higher oil content found for genotypes in Barbalha, where the crop was irrigated. Higher amounts of stearic (C18: 0) and oleic acids (C18: 1) were observed for the oil from Patos, while for linoleic acid (C18:2) a higher content was found in Barbalha oil. As for sterols, campesterol, stigmasterol and delta 5 avenasterol were more abundant for samples from Barbalha, and sitosterol for samples from Patos (p <0.05). Some figures observed for some fatty acids, sterols, density and refractive index diverged from the identity characteristics described in Codex Alimentarius (2001), reinforcing the need to set up a national database that can support future changes in this standard. Neste trabalho foram avaliadas sementes de 14 genótipos de gergelim, oriundos de ensaios realizados em delineamento ao acaso, com cinco repetições, cultivados em Patos, na Paraíba, e em Barbalha, no Ceará, em ambientes de sequeiro e irrigado, respectivamente. As sementes foram avaliadas quanto à composição centesimal e quanto ao teor de aminoácidos. No óleo, foram determinados o perfil em ácidos graxos e esteróis, além de características do padrão de identidade e qualidade. Foram observadas diferenças significativas (p<0,05) entre os locais para o teor de óleo e de proteína, sendo o teor de óleo superior para Barbalha, onde o cultivo foi irrigado. Houve diferença significativa (p<0,05) entre as médias de Patos e de Barbalha para os ácidos graxos, sendo que os teores de ácidos esteárico (C18:0) e oleico (C18:1) foram maiores para Patos, enquanto o de ácido linoleico (C18:2) foi maior para Barbalha. Quanto aos teores de esteróis, campesterol, estigmasterol e delta 5 avenasterol, foram maiores para o óleo das amostras de Barbalha, enquanto o de sitosterol foi maior para amostras de Patos (p<0,05). Algumas diferenças foram observadas quanto a ácidos graxos, esteróis, densidade, índice de refração e padrão de identidade, para o óleo de gergelim, do Codex Alimentarius (2001), reforçando a necessidade de construir-se uma base de dados nacional, que possa subsidiar futuras alterações neste padrão.Palavras-chave: óleo, esteróis, ácidos graxos.
