Response Surface Methodology and SPF Determined the Photo-Protective Capacity of Tagetes Patula Against Uv-B Radiations

Abstract

The present study investigates the solar radiation protective competency in Tagetes patula extract. The Tagetes extract can be used as therapeutic remedy against the harmful erythemal solar-rays and protect soft & sensitive skin from sun tanning and sun poisoning. Tagetes extract have been treated combinedly with ultrasonication and ethanol followed by filtration. Filtered ethanol extract diluted in a significant quantity of ethanol and undergone for UV-spectrophotometer analysis, where ethanol was used as a reference. Finally, the Mansur equation evaluates the significant sun protection factor (SPF) value of Tagetes patula extract. This study demonstrated the Tagetes patula extract have a remarkable tendency to reflect the harmful solar UV-B rays. Tagetes patula flower and leaf extract had showed the significant sun protection factor value, reflected as (SPF-30) and (SPF-12), respectively. However, the Response surface methodology significantly establishes the correlation between the reflection and photon energy. The studied erythemal factor have been optimized and evaluated through the optimization plot and shows the significant positive correlation between the reflectance and erythemal response factors. In addition, Tagetes patula leaves (NRL) and (NRF) flower extract has application on UV-exposed skin, and help to prevent the skin tissues and cure the sensitive skin from harmful effect of the UV-B rays. This study concluded that NRF extract of Tagetes patula had found greater competency and compatible than NRL extract, in terms of reflectivity and SPF property.
