Abstract
Magnetized water or clustered water is an effective solvent and has the ability to dissolve the nutrients easier and faster than purified water. The objective was to explore the effect of magnet on the constituents of aqueous medicinal plants extracts. Aqueous extracts (infusion or overnight; 1% w/v) of Cinnamomum verum (cinnamon) bark, Salvia officinalis (sage) leaves, Zingiber officinale Rosc (ginger) tuberous and Symphytum officinale (comfrey) seeds were prepared and then divided into two parts, one part was exposed to magnetic disc (0.15 Tesla) for 1 hour. The UV-visible spectra of each extract were obtained and the total flavonoids, allantoin and the reducing power were determined. The UV-visible spectra showed changes in the magnitude of the absorbance peak, appearance of new peaks and shifted peaks in the magnetized aqueous extract compared with non-magnetized extracts. The changes in the total flavonoids, allantoin and the reducing power in the magnetized extract did not follow specific pattern. The magnet induces changes in the constituents of medicinal plants via its effect on the electrical properties of water. Key words: Medicinal plants, magnet, antioxidants
