TL;DR: In this paper, the location and nature of cyanogenic compounds in kusum oil were determined using chromatographic and infrared spectroscopy methods, and it was shown that at least two glyceride molecules are involved.
Abstract: Chemical methods, chromatography and infrared spectroscopy have been applied to ascertain the location and nature of the cyanogenic compounds in kusum oil. Observations indicate the cyanogenic compounds to be a part of glyceride molecules in which one of the hydroxyl groups of the latter is bonded to the cyanogenic compound through an ether linkage. Chromatographic behavior of the isolated cyanogenic compounds further indicates that at least two glyceride molecules are involved. These glycerides are predominantly esterified with saturated fatty acids.

TL;DR: In the present study, the low-cost non-edible kusum (Schleichera triguga) oil with a substantial amount of free fatty acid (FFA) was utilized for biodiesel synthesis and important fuel properties was compared with ASTM 6751 and DIN EN 14214.
Abstract: In the present study, the low-cost non-edible kusum (Schleichera triguga) oil with a substantial amount of free fatty acid (FFA) was utilized for biodiesel synthesis In pretreatment step, FFA was reduced by the acid catalyzed esterification method Then, response surface method (RSM) in conjunction with centre composite design (CCD) containing 30 experimental runs were statistically employed for process optimization and kinetic study for the base catalyzed transesterification process A statistical model predicted highest fatty acid methyl ester (FAME) yield of 9737% at the optimal values of process parameters as follows: sodium methoxide concentration 09 wt% of oil, Methanol to oil molar ratio 9:1, temperature 589 ℃ and reaction time 585 min Using these optimal parameters under experimental conditions in three independent replicates an actual FAME content of 9814% was obtained which was in reasonable agreement with predicted one The developed kinetic model suggested a 18(th) order reaction with activation energy of 3142 kcal mol(-1) and frequency factor of 553×10(19) L mol(-1)min(-1) Furthermore, Important fuel properties of kusum oil biodiesel (KOB) was compared with ASTM 6751 and DIN EN 14214 The viscosity was found to be 534 Cst at 40 °C and the flash point was 152°C
