Conduritol F, the discriminant marker between C. wilfordii and C. auriculatum by 1H NMR spectroscopy

Quantitative 1H nuclear magnetic resonance (qNMR) spectroscopy is a powerful and versatile technique to enable the absolute quantification of specific components in a mixture with excellent reproducibility and robustness. In the present study, qNMR analysis was applied to conduritol F, a chemical marker with the potential to distinguish between C. wilfordii and C. auriculatum. We found that the signals of H-5 and H-6 of conduritol F were...
