Anti-inflammatory and antiviral activities of compounds from the fruit of Pouteria caimito

Abstract

Pouteria caimito is a commercially valuable tropical fruit tree and has medicinal effects in Brazilian folklore. In this thesis, thirteen compounds were isolated for the first time from the fruit of P. caimito by ethanol extraction and various chromatographic column chromatography methods. The thirteen compounds were identified by NMR, HR-ESI-MS and various physicochemical data to contain nine triterpenoids. The results of activity screening experiments showed that compounds 2, 3 and 5 exhibited anti-inflammatory activity, while most of the triterpenoids exhibited anti-RSV, and anti-HSV activity to varying degrees. Based on these results, the content of compound 5 was determined due to its good pharmacological activity to be 13.3250 mg/kg in the fresh fruit. This study scientifically demonstrated the health benefits of consuming P. caimito fruits and also provided new ideas for further development and utilization of P. caimito. It not only has good potential as an anti-inflammatory or antiviral functional food but also can be considered a natural source of triterpenoids.
