Method for identifying authenticity and origin of Panax quinquefolius based on terahertz spectroscopy |
| abstract |
Provided is a method for identifying authenticity and origin of Panax quinquefolius based on terahertz spectroscopy. The time domain spectral information of the Panax quinquefolius sample is obtained, and converted into the frequency domain spectral information by Fourier transform to calculate a terahertz absorption spectrum. The identification is performed by observing whether there are characteristic absorption peaks of pseudoginsenoside F11 in the terahertz absorption spectrum. |
