Analysis of the chemical components of pomelo peels (Citrus grandis [L.] Osbeck) from different cultivars by using supercritical CO2 fluid extraction and ultra‐high‐performance liquid chromatography‐tandem mass spectrometry

Five pomelo cultivars (i.e., Citrus grandis cv. Shatianyou, Citrus grandis cv. Guanximiyou, Citrus grandis cv. Yuhuanyou, Citrus grandis cv. Duweiwendanyou and Citrus grandis cv. Liangpingyou) from different origins in China were selected to analyze their components by using supercritical CO2 fluid...

More Information
Summary:Five pomelo cultivars (i.e., Citrus grandis cv. Shatianyou, Citrus grandis cv. Guanximiyou, Citrus grandis cv. Yuhuanyou, Citrus grandis cv. Duweiwendanyou and Citrus grandis cv. Liangpingyou) from different origins in China were selected to analyze their components by using supercritical CO2 fluid extraction coupled with ultra‐high‐performance liquid chromatography‐tandem mass spectrometry. A total of 45 compounds were identified in the supercritical CO2 fluid extracts of the pomelo peels from the five cultivars. These compounds included eight flavonoids, 18 coumarins, four organic acids, three aldehydes, and 12 other compounds, which were identified using the obtained MS data and by comparison with commercial standards, orbitrap Chinese Traditional Medicine Library, and previous literature. Twenty‐five of the identified compounds were detected for the first time in the pomelo peel extracts. Results suggested that the pomelo peels of C. grandis cv. Shatianyou contained the most natural chemical compositions. The pooled result may offer scientific evidence for further development and utilization of pomelo peels and a route for screening appropriate varieties for various demands.
