12. NMR

NMR analyses the number and types of functional groups in molecules by studying

hydrogen and carbon spectrum, and then conclude the structure of molecules. At present,

NMR is mostly used for structural analysis of carbohydrates, proteins and nucleic acids.

Recently, some laboratories have proposed the identification of natural products by

NMR and tested the Saw Palmetto oil. We collected 10 samples and compared them. We

found that the Saw Palmetto oil could not be identified by NMR alone, and found out

the cause of confusion.
