Abstract
Naringenin, a flavonoid found in several fruits like oranges, grapefruit, and bergamot, exhibits a wide range of biological effects. These include antidiabetic, antidepressant, antiatherogenic, antitumor, immunomodulatory, anti-inflammatory, hypolipidemic, antioxidant, peroxisome proliferator-activated receptors (PPARs) activation, hepatoprotective properties, memory enhancement and DNA protective properties. The aim of this current study is to develop a simple and precise UV spectrophotometric technique for measuring Naringenin Active Pharmaceutical Ingredient (API) in bulk and vaginal niosomal nanoformulation using PBS (Phosphate buffer solution) pH 4.5. The absorption peak of Naringenin was identified at 287 nm, and it adhered to Beer's law within the concentration range of 2 to 14 µg/ml. The calibration curve demonstrates a linear relationship between absorbance and concentration within the range of 2 to 14 µg/ml. The determined limit of detection and limit of quantification were found to be 0.587672µg/mL and 1.780824µg/mL, respectively. The validity of the method was assessed for repeatability, accuracy and precision. The results obtained indicated minimal intraday and interday variation. The excipients in the nanoformulation did not interfere the analysis. The developed analytical UV spectrophotometric method is simple, rapid and consistent, making it suitable for estimating the drug in both bulk and nanoformulation.
