“…In addition, Several methods have been reported for simultaneous determination of mixture of these active ingredients like UV spectrophotometry [23,24], electrochemical method [25][26][27], chemiluminescence [28], capillary electrophoresis [29][30][31][32], high-performance liquid chromatography (HPLC) [33][34][35][36]and NIR FTIR [37]. The objective of this study is to develop a simple, rapid, sensitive and selective method for determination of rutin and ascorbic acid mixture in their pure forms and pharmaceutical dosage forms.…”

“…In addition, ascorbic acid (AA) is a chemically electroactive substance which often coexists with rutin in plants, crude drugs, pharmaceutical preparations (especially compound rutin tablets) and other biological samples. What is worse, the oxidation peak potential of AA is very close to that of rutin, indicating a poor selectivity and serious interfering effect for the rutin detection in real samples [19,20]. Therefore, the electrochemical responses of rutin in the presence of AA on the NH 2 -Fe 3 O 4 NPs-ErGO/GCE were studied.…”

“…Electrochemical methods have the virtues of low-cost apparatus, high sensitivity, wide linear range and simplicity. Due to the electroactivity of rutin, various electrodes have been modified and explored for the detection of rutin [12,13,14,15,16,17,18,19,20], and their typical analytical figures of merit for rutin analysis are compared and summarized in Table 1. In order to amplify the response signal fundamentally and improve the detection sensitivity practically, it is still important and necessary to develop new electrochemical sensors for rutin detection at the nanomolar level.…”

A new electrochemical sensor for nanomolar rutin detection based on amine-functionalized Fe3O4 nanoparticles and electrochemically reduced graphene oxide nanocomposite modified glassy carbon electrode (NH2-Fe3O4 NPs-ErGO/GCE) was fabricated through a simple method, and the X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscope (SEM), transmission electron microscope (TEM), vibrating sample magnetometer (VSM) and electrochemical technique were used to characterize the modified electrode. The electrochemical behavior of rutin on the Fe3O4 NPs-ErGO/GCE was studied in detail. The electrochemical response of rutin at this modified electrode was remarkably higher than that of the bare GCE or other modified GCE (GO/GCE, Fe3O4 NPs-GO/GCE, and ErGO/GCE). Under the optimum determination conditions, Fe3O4 NPs-ErGO/GCE provided rutin with a broader detection range of 6.0 nM–0.1 µM; 0.1–8.0 µM and 8.0–80 µM, a minimum detectable concentration of 4.0 nM was obtained after 210 s accumulation. This novel method was applied in determination of rutin in pharmaceutical tablets and urine samples with satisfactory results.

“…Various methods for the determination of rutin in drugs and extractants have been reviewed [3]. The simultaneous determination of rutin and ascorbic acid in pharmaceutical products has been achieved by UV spectrophotometry [4,5], voltammetry [6][7][8], and HPLC [9,10]. However, high performance liquid chromatography [11,12] and capillary electrophoresis [13,14], were the commonly used methods only for separating and determining rutin in plants.…”

The components were separated isocratically with a mobile phase consisting of methanol-buffer solution. The buffer solution is prepared from potassium dihydrogen phosphate KH 2 PO 4 0.01 M solutions adjusted to pH 3.2 with 85% ortho-phosphoric acid. The isocratic elution begun with linear equilibrium elution initial at 45% methanol over the first 0.5 minutes, followed by elution with 60% methanol over the next 8 minutes and then elution with 45% methanol for 2 minutes Abstract Objective: A combination of rutin and ascorbic acid were exploited in several pharmaceutical activities and so simple and high sensitive liquid chromatographic method for the simultaneous determination of the cited ingredients in methanolic extracts of different Libyan herbal plants was proposed. Methods: The chromatographic analysis was performed using 250 × 4.6 mm Brownlee BIO C18 column, 5 µm particle size, with UV detection at 254 nm and isocratic elution of methanol-phosphate buffer pH 3.2, which is initially in 45:55 (v/v) for 0.5 min (equilibrium state), then varied to 60:40 (v/v) isocratic for 8 min and then back to 45:55 for 2 min, at a flow rate 1 ml/min and at ambient temperature.
