Abstract: This research aims to investigate the inhibitory effects of herbal teas on alpha-glucosidase enzyme activity. Ten typesof commercially available herbal teas were evaluated, including Gymnanthemum extensum, Momordica charantia, Moringa oleifera, Mitragyna speciosa, Pluchea indica, Solanum torvum, Plukenetia volubilis, and a mixed herbal formula consisting of Gynostemma pentaphyllum, Pandanus amaryllifolius, and Hibiscus sabdariffa. The results revealed that several selected herbal teas exhibited significantly higher alpha-glucosidase inhibitory activity than the standard drug, acarbose, at a concentration of 5 mg/mL; notably G. extensum, M. charantia, and M. oleifera. Furthermore, increasing the steeping time significantly enhanced the inhibitory activity (plt;0.05). These findings demonstrate the potential benefits of herbal teas for health promotion and diabetes prevention. Additionally, this study provides scientific evidence regarding the optimal steeping duration to maximize the therapeutic benefits of herbal tea consumption.
