Quantification of Mangiferin from the Bioactive Fraction of Mango Leaves (Mangifera indica L.) and Evaluation of Wound-Healing Potential

Abstract

Burns refer to damage to the skin's surface caused by exposure to high temperatures, which can be due to factors such as oil, water, electricity, fire, sun exposure, and chemicals. Prompt and appropriate treatment is essential to prevent undesirable consequences. Thus, this study aimed to quantify mangiferin, a potential treatment for burns, in the bioactive fraction of mango leaves (Mangifera indica L.) and evaluate its effectiveness in healing burns.The methods employed included thin-layer chromatography (TLC)-densitometry with validation measures, including linearity, detection and quantification limits (LoD and LoQ), precision, accuracy, and quantification. The bioactive fraction was formulated in membranes at concentrations of 5%, 10%, and 15%. These membranes were applied to rabbits previously subjected to six wound burns, and the healing progress was monitored by measuring burn diameter using a vernier caliper every 3 days for a total of 21 days. Mangiferin, the active compound, was detected at a wavelength of 257 nm. Test results yielded a linearity equation, y = 76496x + 2935.7, with a correlation coefficient value of 0.9957, a detection limit of 2.01 µg/mL, a quantification limit of 6.07 µg/mL, a coefficient of variation ranging from 0.59% to 3.33%, and an accuracy range of 99.18% to 100.9%, with mangiferin levels at 208.31 µg/mL. The membrane preparations of the bioactive mangiferin fraction were evaluated on second-degree burns in rabbits, with concentrations of 10% and 15% showing the most effectiveness.
