“…No less common or unusual fatty acids such as cyclic, epoxy or hydroxy fatty acids were observed. The absence of such less common fatty acids appears to be typical for most oils from plants of the Fabaceae family but in the seed oils of species of the Albizia and Acacia, which also belong to the Fabaceae family but different genera, fatty acids with cyclic moieties were observed [36]. The fatty acid profile observed in the present work largely agrees with the fatty acid profiles reported previously [27,28] which also indicate similar amounts of saturated fatty acids ( Table 1).…”

Increasing the supply of biodiesel by defining and developing additional feedstocks is important to overcome the still limited amounts available of this alternative fuel. In this connection, the methyl esters of the seed oil of Gliricidia sepium were synthesized and the significant fuel‐related properties were determined. The fatty acid profile was also determined with saturated fatty acids comprising slightly more than 35 %, 16.5 % palmitic, 14.5 % stearic, as well as lesser amounts of even longer‐chain fatty acids. Linoleic acid is the most prominent acid at about 49 %. Corresponding to the high content of saturated fatty acid methyl esters, cold flow is the most problematic property as shown by a high cloud point of slightly >20 °C. Otherwise, the properties of G. sepium methyl esters are acceptable for biodiesel use when comparing them to specifications in biodiesel standards but the problematic cold flow properties would need to be observed. The 1H‐ and 13C‐NMR spectra of G. sepium methyl esters are reported.

“…Literature reports also show that behenic and lignoceric acids were present in the seed oils of the Albizia genus which also belongs to the Fabaceae family. A recent report on the fatty acid composition of Albizia lebbeck and Albizia saman revealed that the seed oil of Albizia saman was found to contain 13.6 and 2.3% of behenic and lignoceric acid, respectively; whereas Albizia lebbeck showed lower contents of these fatty acids (Knothe et al, 2015). The presence of very long chain fatty acids in seed oils in higher amounts is advantageous as it provides an opportunity to employ these oils in low calorie fat applications (Haumann, 1997).…”

SUMMARY:The seeds of Butea parviflora were investigated for oil extraction and the oil was studied for complete physico-chemical properties. The fatty acid profile of the seed oil showed oleic acid (18:1) at 27.5%, linoleic acid (18:2) at 26.4%, palmitic acid (16:0) at 16.1% and behenic acid (22:0) at 14.1% as the major fatty acids. The physico-chemical characteristics of the seed oil were studied for parameters such as free fatty acids (0.71%), iodine value (76.2 g/100g), peroxide value (5.95 ppm), saponification value (177.32 mg KOH/g), unsaponifiable matter (0.82%), phosphorous content (197 ppm), triglyceride analysis, tocols, specific gravity and refractive index following standard procedures.KEYWORDS: Butea parviflora; Fatty acids; Seed oil; Sterols; Tocopherols; Triterpenoid RESUMEN: Aislamiento y caracterización físico-química de aceites de semillas de Butea parviflora. Se ha estudiado la extracción de aceite de semillas de Butea parviflora así como las características físico-químicas completas del aceite. El perfil de ácidos grasos está compuesto de un 27,5% de ácido oleico (18:1), 26,4% de ácido linoleico (18:2), 16,1% de ácido palmítico (16:0) y 14.1% de behénico (22:0) como principales ácidos grasos. Se han estudiado las características físico-químicas del aceite de las semilla tales como los ácidos grasos libres (0,71%), índice de yodo (76,2 g/100 g), índice de peróxido (5,95 ppm), índice de saponificación (177,32 mg KOH/g), materia insaponificable (0,82%), contenido en fósforo (197 ppm), análisis de triglicéridos, gravedad específica e índice de refracción, siguiendo los protocolos recogidos en procedimientos estandarizados.

“…The coronaric acid content of Albizia resembles that of Acacia species with both genera belonging to the Fabaceae family. The mass spectrum of the pyridylcarbinol (picolinyl) ester of coronaric acid is reported (Knothe et al, 2014). Current literatures markedly lacked data and information about synthesis of alkyd resin from Albizia lebbeck seed oil.…”

Alkyd resin was synthesized from the Albizia lebbeck (frywood) seed oil (FWO) and the physico-chemical properties of both the oil and the consequent alkyd resin were studied. Fourier Transform Infra-red (FTIR) spectroscopy was used to investigate the functional groups present in the alkyd resin. MATLAB was used to generate model equations for the extent of reaction for the synthesis of the alkyd resin. The oil extracted from the plant's seeds has a percentage yield of 17.32%w/w, exhibited yellow colour and was liquid at room temperature. Other physico-chemical properties of the oil such as density, specific gravity (30ºC), refractive index (30ºC), viscosity (30ºC), saponification value, iodine value, acid value, free fatty acids and peroxide value were determined to be 0.89g/cm 3 , 0.84, 1.48, 27.064m 2 /S, 207.22mgKOH/g, 122.18gI 2 /100g, 8.98 mgKOH/g, 4.52% and 10.00mEq/kg respectively. The synthesized alkyd resin from frywood seed oil (FWOAR) was dark-brown in colour while that of the commercially prepared alkyd resin (CPAR) was colourless. Physico-chemical properties of FWOAR such as specific gravity (30ºC), viscosity (30ºC), saponification value, iodine value and acid value were investigated to be 47.58, 36.50, 361.85mgKOH/g, 32.33gI 2 /100g and 7.01mgKOH/g respectively. These values, except that of saponification (361.85mgKOH/g vs 263.97mgKOH/g), were not significantly difference when compared to those of CPAR that were determined to be 47.40, 32.34m 2 /S, 263.97mgKOH/g, 48.22gI 2 /100g and 6.31mgKOH/g respectively. Variations in acid value (AV), viscosity, extent of reaction (R e ) and degree of polymerization (D p ) of in-process alkyd sample with time were studied. Viscosity, D p and R e increased with time while AV decreased with time. The IR spectra of the test alkyd resin and the commercially prepared alkyd resin showed that the broad band shoulder around 3859.69cm -1 and 3498.02 cm -1 were due to the OH stretch hydroxyl of the unsaturated fatty acid. The peak value within the range of 2930.93 cm -1 -2933.83cm -1 observed in both alkyd resins corresponds to SCN and the peak height observed around 1727.31cm-1 was due to CO stretch of unsaturated cyclic ester of monoglyceride. The presence of vinylidene compounds of unsaturated fatty acid of diglyceride and triglyceride were suggested in the peaks observed in both alkyds. From the performance tests, it was observed that the drying trend was faster in CPAR than FWOAR. CPAR showed higher resistant to water and acidic medium than FWOAR and both were poorly resistant to alkaline medium. Results so far obtained from this study suggest that the FWO and FWOAR exhibited good performance characteristics even when FWOAR was compared with the commercially produced alkyd resin and there are similar functional groups in the compounds observed in the absorbance of IR spectra.
