Tissue-Specific Metabolite Profiling of Cyperus rotundus L. Rhizomes and (+)-Nootkatone Quantitation by Laser Microdissection, Ultra-High-Performance Liquid Chromatography–Quadrupole Time-of-Flight Mass Spectrometry, and Gas Chromatography–Mass Spectrometry Techniques

Cyperus rotundus L. is a plant species commonly found in both India and China. The caused destruction of this plant is of critical concern for agricultural produce. Nevertheless, it can serve as a potential source of the commercially important sesquiterpenoid (+)-nootkatone. The present work describes comparative metabolite profiling and (+)-nootkatone content determination in rhizome samples collected from these two countries. Laser dissected...
