Abstract

Recent theoretical developments have revealed that, it is necessary to find measurement methods that are characterized by accuracy, simplicity and speed, and must be included in green chemistry. In this study, a method was developed to measure the manganese ion in the flowers of some medicinal plants by using continuous flow injection technique and hydrogen peroxide to oxidize the manganese present in the plant to Mn+7 (potassium permanganate) of violet color, which was measured by a homemade system at the length of540  nm wavelength and under standard conditions where the flow rate was 1.8 ml/min for hydrogen peroxide and potassium hydroxide. This method was linear within the range from 0.10 to 36.0 mg/L, with a detection limit of 1.080 and RSD %. 1.7 %.A sample of 10 mg of dried flowers was taken from four different medicinal plants (Matricaria recutita, Lavandula angustifolia, Viola, Gardenia). This developed method was successful in estimating manganese, as Paired t-test 95% was used. Statistical tests showed that there is no significant difference between the traditional method and the developed method, so it is possible to use the developed method as an alternate method for the estimation of manganese in plants.
