Characterization of Pentadesma butyracea sabine Butters of Different Production Regions in Benin

Abstract

Pentadesma butter (Pentadesma butyracea, sabine, clusiaceae) is an extract of the kernels of tree fruits in West Africa and similar to shea butter. The study of the fatty acid composition, triacylglycerols, sterols and tocopherols of Pentadesma butter was carried out on seeds collected in ten production areas in Benin. The results obtained show that the composition in fatty acids is characterized by the presence of stearic acid and oleic acid, which represent nearly 96% of the total fatty acids. The triacylglycerols profile of the different butters is marked by the overwhelming presence of the triacylglycerols SOS and SOO. The unsaponifiable fraction shows, for the sterolic composition, a predominance of stigmasterol (nearly 68% of the total sterols) whilst the b-tocopherol is the main tocopherol.

Physico-Chemical characteristics of shea butter(<i>Vitellaria paradoxa</i> C.F. Gaertn.) oil from the Shea district of Uganda

“…Saponification and iodine values of shea oil exhibited in this study are also lower than saponification and iodine values for most vegetable oils [17,18,19]. The peroxide value (2.1-2.5 meq/kg), saponification value (160-192 mgKOH/g) and iodine value (39-41 I 2 g/100g) are, however, similar to those reported previously for the shea oil.…”

Phytochemical composition, acute toxicity and phytohormonal activity of hydroalcoholic extract of Pentadesma butyracea (Clusiaceae Sabine (1824)) seeds

“…Previously, phytochemical investigations on bark, roots and leaves showed the presence of similar phyto-chemical compounds in this plant (Tchobo et al, 2007(Tchobo et al, , 2013Noudogbessi et al, 2013a). However, some compounds such as coumarins and saponosides found by Noudogbessi et al (2013a) were not detected in P. butyracea hydroalcoholic seeds extracts.…”

Quantitative trait loci (QTLs) analysis of palm oil fatty acid composition in an interspecific pseudo-backcross from Elaeis oleifera (H.B.K.) Cortés and oil palm (Elaeis guineensis Jacq.)

“…The oil fraction was recovered with a syringe and stored at -20°C until chemical analysis. Fatty acids extracted by a standard procedure were converted into fatty acid methyl esters (FAMEs), and FAMEs were analyzed by gas chromatography (GC) according to the AFNOR method NF T60-233/1977T60-233/ (AFNOR 1977 using Tchobo et al (2007) protocol with minor modifications. Each oil sample (≈40 mg) was added to 3 ml of sodium methylate solution with phenolphthalein in a 25-ml round bottom flask.…”
