“…The percentage of vegetable oil in Nyamplung seeds is high, around 40-73 % [5], The major content in Nyamplung seeds is oleate and linoleate [6][7][8][9]. This research used Nyamplung seeds in preparation of polyurethane membrane which was reacted with hexametylene-1,6-diisocyanate (HMDI composition was varied to possess the optimum membrane condition).…”

“…The oil obtained by extraction with n-hexane alone consisted of palmitic (14.7 ± 0.2%), palmitoleic (0.2 ± 0.0%), stearic (15.7 ± 0.3%), oleic (37.6 ± 0.2%), linoleic (30.4 ± 0.3%), linolenic (0.2 ± 0.0%), arachidic (0.8 ± 0.0%), eicosenoic (0.1 ± 0.0%) and behenic (0.2 ± 0.0%) acids. Unsaturated fatty acids, such as oleic acid and linoleic acid, predominated, as in other published studies of Calophyllum oil [8,[10][11][12]30]. However, the oil also contained saturated fatty acids, in the form of palmitic acid and stearic acid.…”

OATAO is an open access repository that collects the work of Toulouse researchers and makes it freely available over the web where possible. This is an author-deposited version published in : http://oatao. This study investigated the use of a mixture of n-hexane and methanol as a binary solvent for the direct oil extraction and resin separation from Calophyllum seeds, in a single step. Optimal oil and resin yields and physicochemical properties were determined by identifying the best extraction conditions. The solvent mixture tested extracted oil and resin effectively from Calophyllum seeds, and separated resin from oil. Extraction conditions affected oil and resin yields and their physicochemical properties, with the n-hexane-to-methanol ratio being the most critical factor. Oil yield improved as n-hexane-to-methanol ratio increased from 0.5:1 to 2:1, and resin yield increased as methanol-to-n-hexane ratio increased from 0.5:1 to 2:1. Physicochemical properties of oil and resin, particularly for acid value and impurity content, improved as the n-hexane-to-methanol ratio decreased from 2:1 to 0.5:1. The best oil (51% with more than 95% triglycerides) and resin (18% with more than 5% polyphenols) yields were obtained with n-hexane-to-methanol ratios of 2:1 and 0.5:1, respectively, at a temperature of 50°C, with an extraction time of 5 h. The best values for physicochemical property of oil were a density of 0.885 g/cm 3 , a viscosity of 26.0 mPa.s, an acid value of 13 mg KOH/g, an iodine value of 127 g/100 g, an unsaponifiable content of 1.5%, a moisture content of 0.8% and an ash content of 0.04%.

“…The antioxidant potential and the attenuation of acetaminophen-induced redox imbalance by P. osun were reported recently [22]. Adewuyi et al [23] showed that the acetonides prepared from the seed oil of P. osun has no antibacterial activities but the leaves ethanolic extract of the plant does.…”

Objective: This study was carried out to purify and characterize a carbohydrate-binding and cell-agglutinating protein, lectin, from Pterocarpus osun seeds and also to evaluate its antioxidant and antibacterial potential. Methods: Isolation and purification of the lectin were done by ammonium sulphate precipitation and size exclusion chromatography on Sephadex G-100. Physicochemical properties of the lectin were determined and antioxidant activity was evaluated by DPPH radical scavenging, lipid peroxidation inhibition and ferric reducing antioxidant potential assay. A disc diffusion method was used for antibacterial effect. Results: Lectin was detected in the seeds and was able to agglutinate native and enzyme-treated rabbit erythrocytes but only enzyme-treated erythrocytes of human blood were agglutinated. Mannose, Maltose and α-methylmannoside inhibited the divalent cation-independent hemagglutinating activity, which was stable up to 60°C and at pH range of 3-13. It showed antioxidant activity with IC50 of 1.17 ± 0.08, 0.58 ± 0.03, and 2.51 ± 0.03 mg/ml for those methods respectively. No antibacterial activity was observed. Conclusion: Pterocarpus osun seeds lectin possess properties similar to other lectins from Dalbergieae tribe and its ability to scavenge free radical and inhibit lipid peroxidation show the presence of a valuable health promoting agent in the seeds.
