| Abstract: |
Quercetin (QCT), as an important flavonoid, has different properties including neuroprotective, anti-hyperlipidemia, decreasing blood pressure and neuroprotective effects. Hence precise determination of quercetin is noteworthy. Herein, a fast, simple, highly sensitive, and new fluorescent sensor was prepared based on Achillea Millefolium extract carbon dots stabilized on sodium alginate structure (CD/Na-Al). For confirm the reliability of synthesized sensor some characterization analysis were performed such as FT-IR and TEM. The CD/Na-Al was applied for the accurate recognition and measurement of QCT molecule. The operation mechanism for the analytical procedure was based on "turn-off" the fluorescence emission signal in 440 nm. The dynamic linear range was obtained in the range of 1–25 and 25–110 µM, with detection of limits equal to 0.32 and 3.9 µM respectively. The observations confirmed that the present method was able to detect trace amounts of quercetin in black tea and sur cherry with satisfy results. [ABSTRACT FROM AUTHOR] |
