- •
A rapid method was developed to quantify cellulose content in tobacco using 13C CP/MAS NMR with spectral deconvolution.
- •
A designed NMR rotor was used to eliminate the unfavorable impact of the instability and high-speed rotation for internal standard.
- •
Spectral deconvolution technique eliminated the interference of overlapping peaks and excessive noise.
- •
The method showed good agreement and small average deviations between standard chemical method and values by 13C CP/MAS NMR spectra.
