Mid-infrared spectroscopy and short wave infrared hyperspectral imaging-A novel approach in the qualitative assessment of Harpagophytum procumbens and H. zeyheri (Devil's Claw)

- Two Harpagophytum species are used interchangeably to treat inflammation and are resolved by spectral methods here.
- Chemical congruency and bio-equivalence of the two species have not been proven.
- Multivariate analysis models for species authentication were developed.
- The two developed models had good statistics with R2X values of 0.86 and 0.99 for MIR and SWIR data, respectively.
