- Abstract
Medicinal plants, are resources of traditional medicines, have played a significant role in human culture throughout history. The connect of traditional knowledge with contemporary scientific findings, display the potential of these plants for nutritional and pharmaceutical applications. This study aimed to investigates the antioxidant activity and phenolic compositions of seven medicinal plants (Kaempferia parviflora, Hibiscus sabdariffa, Phyllanthus emblica, Terminalia chebula, Terminalia bellirica, Gynostemma pentaphyllum, and Stevia rebaudiana) from Kalasin Province, Thailand. 1,1-diphenyl-2-picrylhydrazyl (DPPH) and ferric-reducing antioxidant power (FRAP) assays were used to evaluate the the antioxidant activities. The qualitative method was used for the phytochemical screening. Additionally, reverse-phase high-performance liquid chromatography (RP-HPLC) analysis reveals their phenolic compositions. Results revealed that phenols, flavonoids, and terpenoids were found in all medicinal plants studied, with flavonoids and phenols most predominant. Notably, P. emblica and T. bellirica show significant antioxidant properties and high levels of phenolics and flavonoids. P. emblica had the highest phenolic acid concentrations, with ρ-coumaric (79.43 µg/g), chlorogenic (45.22 µg/g), and ferulic acid (29.58 µg/g) being dominant. The research emphasizes the value of these plants in developing functional foods and pharmaceuticals, underlining the importance of conserving biodiversity and traditional knowledge for future health product innovation.
