“…Sua madeira é usada para produção de palitos de fósforo, celulose, canoas e caixotaria entre outros usos. O óleo produzido pelas sementes já foi avaliado com sucesso para a produção de biodiesel (NISHIOKA;ESCALANTE, 1997;LORENZI, 2002;SOUSA et al, 2007;DWIVEDI et al, 2011).…”

O objetivo do trabalho é mostrar a produção do biodiesel por meio do fruto da cutieira (Joannesia Princeps Vell.) e comparado com outros biocombustíveis, mostra o ganho que temos com a produção desse biodiesel. O objetivo do trabalho é apresentar sobre a história do biodiesel no Brasil e mundo, o processo de extração para a produção de biodiesel, as principais misturas utilizadas e como são os ganhos comprados a outras matérias primas. O baixo valor de produção, um grande ganho energético e o aprimoramento do estudo de uma arvore nativa brasileira ainda é pouco conhecido. Essa nova tecnologia contribui para aumentar a sustentabilidade e os incentivos para estudos da cutieira. Apesar de a matéria prima ser pouco conhecida com grande valor econômico e com potencial energético pouco estudado, precisa ser mais divulgada para estudos futuros e melhoria na produção do biodiesel. O biodiesel da cutieira tem muito potencial, mas precisa ser mais estudado a fundo para produção futura em larga escala.

“…In folk medicine, this plant is indicated as a purgative, for menstrual disorders, pernicious fever, antimicrobial, syphilis, scrofulosis and swelling. The oil from the root bark is used as a laxative [3][4][5][6] and the extract from the seeds exhibits strong anthelmintic activity, being used in folk medicine, due to the induction of intestinal motility [1,[7][8][9][10][11]. The seeds contain 37-55% of a viscous, slightly yellow oil that is useful for medicinal and industrial purposes.…”

In the present work, we report the characterization, after isolation, of a triglyceride (TAG) from seeds of Joannesia princeps vell, a Euphorbiaceae, through extraction in a soxhlet apparatus, using hexane as an extracting solvent. The proposed structure of TAG was determined by spectrometric analyses: high-resolution GC/MS; I.V.; R.M.N. 1H and 13C. Spectra of RMN ( 1 H; 13 C; H x H COSY e DEPT-45) indicate that all signals observed in the spectra belong to a single compound, a TAG containing two identical units and one different. A structure is proposed that, through hydrolysis in methanol/sodium methoxide, leads to two units of methyl linoleate ester and one of methyl oleate ester. Therefore, a molecular weight of 880g.mol-1 and formula C57H100O6 can be proposed. Confirmation of the structure is also done by comparing the proposed structure with another TAG described in the literature. Reaction of the mixture produced by basic hydrolysis with dimethyl-disulfide (CH3-S-S-CH3) confirms the positions of the unsaturations of the oleic and linoleic units; in addition to demonstrating the obtaining of a product originating from a thermal mechanism, under mass spectroscopy analysis. Therefore, in general, this TAG with a mild and slightly yellowish aroma is a mix of omega-9 and omega-6; which corresponds to approximately 40% of the seed mass, in addition to being probably one of the main responsible for physiological activities described in the literature. Another predominant TAG with a molecular mass of 878g.mol -1 , was detected by high-resolution mass spectroscopy, after a period of seed storage in a desiccator.
