Medicinal plants extracts are a rich natural source of active phytochemicals (Polyphenols) that are known to have important health-enhancing properties. This study determines the total content of polyphenols of nine medicinal plants extracted using the accurate UV-vis spectroscopic method, along with the Orange Data Mining Tool (ODMT). The total content of polyphenols for the selected medicinal plant extracts (Daucus Carota L., Ruta Chalepensis L., Anisosciadium DC., Thymus Vulgaris, Senna Alexandrina, Myrtus Communis, Silybum Marianum Flower, Silybum marianum Leaves, and Rosa moschata) was measured using gallic acid as a standard. The intended method requires a maximum of 1 mg of Gallic acid and only 1 mg of the plant extract. The wavelength range of the maximum absorption in the UV-vis spectrum was about 270 nm. For polyphenols, the purposed method linear dynamic concertation range (44.67 to 334.7 mg GAE/g DW) with a recovery percentage range of 95.3–104.3%. This method is easy, fast, accurate, and less expensive than the Folin Ciocalteu method. |
