Illigera aromatica S. Z. Huang et S. L. Mo and Illigera henryi W. W. Sm., belonging to the genus Illigera (Hernandiaceae), are used as herbal medicines for promoting blood circulation and treating tuberculosis. Actinodaphnine, the major bioactive alkaloid, plays an important role in the quality controls of the herbs. In the present study, a rapid, simple, accurate, and precise proton quantitative nuclear magnetic resonance (1H-qNMR) method was developed to determine the content of actinodaphnine in I. aromatica and I. henryi. DMSO-d6 enabled satisfactory separation of the signals to be integrated in 1H NMR spectrum. 1,4-Dinitrobenzene was selected as an internal standard. The limits of determination and quantitation were 0.005 and 0.038 mg/mL, respectively. This work implied that 1H-qNMR represents a feasible alternative to HPLC-based methods for quantitation of actinodaphnine in I. aromatica and I. henryi and is suitable for the quality control of I. aromatica and I. henryi.
