Through the analysis of NMR spectrum:
1. We only found one characteristic peak of Soybean oil (1.5 ppm) and Olive oil (25
ppm), and one suspected characteristic peak of Saw palmetto oil (65 ppm), which is far
from enough for authenticity identification.
2. The above spectra are both repetitive and different. The components of vegetable oils
are complex, and the basic functional groups are similar. The origin, harvesting time and
processing methods will cause the differences of components.
Therefore, it is difficult to identify Saw palmetto oil only by NMR testing technology.
