The fatty acids of neem oil and their reduction products

Abstract: The seed oil of Melia (Azadirachta) indica has been critically re-examined particularly with reference to fatty acid composition, using the gas chromatograph as a means of analytical control. Behenic acid has been discovered as a component and the presence of myristic acid and lignoceric acid verified. The limitations of some earlier methods of analysis are illustrated. A suitably purified neem oil has been successfully reduced to the corresponding saturated and unsaturated alcohols by a selective sodium reduction procedure of potential industrial value. The reduction products and their acetyl esters have been examined by gas-liquid chromatography. A comparison is made between the results obtained from methyl esters as derivatives and those obtained from the alcohols and their acetates.
