Outline of Final Research Achievements

The root of Chinese licorice (Glycyrrhiza uralensis) is used worldwide as a medicinal herb. The goal of this study was to understand changes in the concentrations and compositions of four medicinal compounds in the root of Chinese licorice during pre- and post-harvest treatment. This study provided an approach to increase the target compound concentrations in Chinese licorice for different market demands (drugs, cosmetics, and food).
Mentha arvensis L. var. piperascens, known as Japanese mint, belongs to the Lamiaceae family with high menthol content. The present study was carried out to elucidate the optimal UV irradiation techniques (wavelength, intensity and irradiation period) for essential oil (menthol) production in the leaves of Japanese mint under controlled environment.
