I isolated a compound from plant source and it is only soluble in hot chloroform with the melting point of 60 degree. I have taken H-NMR and it clearly shows the characteristic peak of -CH2 group @ 1.2 ppm with the integration value of 69 which suggests that it could be fattyacid or hydrocarbon. But C-13 NMR gave relatively less number of peaks that is only 8 peaks in the spectrum. How can I correlate with 8 carbons and more than 70 protons. Please help me through.

May be it is a highly symmetrical structure, with one quaternary carbon at the center and four branches each have 8 -CH2 and 1 -COOH. Just guess~~

good guess sir. But there is no possibility of COOH group. If it is highly symmetrical how can i decode the spectrum to find out the structure?

By doing other NMR experiments. Try doing some COSY or HSCQ/HMBC.

 

It would also be worth getting some mass spec data.

^{Yes sir i am about to carry out some mass spectra. The boiling point of this compound is 62 degree. Can it be worth if i go for GC-MS?}
