Abstract:
This study attempts the application of 1H NMR spectra as a characteristic of commercial herbal preparations. 1H NMR spectra of four herbal preparations having the same composition from different manufacturers were compared. 1H NMR spectra of three herbal preparations having different compositions from commercial sources were also examined. 2D NMR TOCSY spectra of the same preparations were also presented for correlation of 1H NMR spectra with herbal composition. Average and standard deviation were derived from 1H NMR spectra of four herbal preparations of the same composition (Triphala) as a comparative analytical method.
Graphical Abstract:
Composition of herbal preparation is correlated with 1H NMR spectra.
