Polyol was synthesised from the seed oil of Lonchocarpus cyanescens by epoxy ring opening reaction with 2‐ethylhexanol. The structural characterization was confirmed using Fourier Transform Infrared and Proton Nuclear Magnetic Resonance ( 1 HNMR). Linolenic (C18:3) and oleic (C18:1) acids are the dominant fatty acids in the seed oil of L cyanescens with an iodine value of 170.46 ± 1.00 g 100 g −1 . The finding of this study showed that the seed oil of L cyanescens can be used to synthesise polyol, which can be used as a starting material for lubricant. Copyright © 2012 John Wiley & Sons, Ltd.
