Abstract

Thirty two diverse Jatropha curcas L. cultivars were analyzed for their oil content by the standard Soxhlet extraction method using&#xA;hexane as solvent. The results were then compared with those obtained by nuclear magnetic resonance (NMR) spectrometer. The&#xA;cultivars had a wide range in oil content, which ranged from 4.8 to 38.8% by the Soxhlet method, and from 6.0 to 38.9% by the NMR&#xA;method. The values of oil content determined by the NMR method were highly significantly correlated (R2 = 0.9929, P<0.0001, n = 32)&#xA;with those obtained using the Soxhlet method. The NMR method is simple, nondestructive,&#xA;rapid, and accurate for the routine analysis&#xA;of oil content in Jatropha
