Comparative Analysis of Extraction Techniques for Enhancing the Photoprotective Activity of Boswellia Species Resin

الملخص

This study investigates the photoprotective properties of Boswellia species resin, commonly known as frankincense, and evaluates its potential as a natural sunscreen agent. Considering the increasing interest in natural skincare alternatives, this research examines the ultraviolet (UV) absorption characteristics and the Sun Protection Factor (SPF) of frankincense extracts. Three distinct formulations were prepared: a standard zinc oxide suspension, a macerated frankincense extract, and a sonicated frankincense extract. Spectrophotometric analysis was employed to determine the absorbance spectra in the 290-320 nm range, and SPF values were calculated using the Mansur equation. In addition, a preliminary phytochemical screening of the frankincense resin was conducted to identify the presence of key bioactive compounds, including flavonoids, polyphenols, and alkaloids. Results indicated that the sonicated frankincense extract exhibited a significantly higher SPF value than the macerated extract and the standard zinc oxide suspension. This suggests that the extraction method significantly influences the photoprotective efficacy of the resin. The phytochemical screening confirmed the presence of flavonoids in frankincense. This study scientifically validates the traditional use of frankincense in skincare, highlighting its potential as a natural source of UV protection. The findings highlight the importance of extraction techniques in optimizing the photoprotective properties of natural products
