Abstract
Research has shown that the consumption of herbal teas is linked with positive effects on the regulation of postprandial blood glucose level. In this study, aqueous and ethanol extractions are performed on four herbal teas to evaluate their phytochemical profiles and functional activities. Investigations of phytochemical contents, antioxidant activities, α-glucosidase inhibitory activities and chemical compositions are carried out through colorimetric analyses and UPLC-Q-Orbitrap HRMS/MS, respectively. Results showed that ethanol extracted samples yielded higher phytochemicals content, antioxidant activities and α-glucosidase inhibitory activities. Moreover, phytochemicals contents presented positive correlation with antioxidant activities and α-glucosidase inhibitory activities. Meanwhile, antioxidant activities displayed similar positive correlation with α-glucosidase inhibitory activities. Among the studied herbal teas, Vine exhibited the highest glucose regulating abilities under both aqueous and ethanol extractions. Results from this study provided evidence that ethanol extracts from herbal teas possess valuable phytochemicals composition for hyperglycemic populations, and are promising candidates for potential applications as functional foods with health promoting effects and natural additives to boost the nutritional value of herbal food products.
