摘要
Ginseng (Panax ginseng) and other species in the Panax genus are among the most famous traditional Chinese herbal medicines. The biological effect of the Panax genus comes from ginsenoside, a class of chemicals found mainly in the Panax genus. This work combines first-principles simulation and Fourier transform infrared spectroscopy to provide theoretical and experimental study on ginsenoside, including infrared absorption spectrum and molecule structure.
