Aims: In the present study, to investigate its chemical stability and the in vitro sun protection
factor (SPF) of Rosa kordesii petal extract in a gel formulation.
Methods: Due to its antioxidant and photoprotective properties, R. kordesii is a promising
candidate for use in cosmetic and pharmaceutical formulations. A high performance liquid
chromatography method was used to evaluate the chemical stability using R. kordesii
extract as marker at 5, 25 and 45 C for 3e4 months. The sun protection factors were
analyzed by ultraviolet (UV) spectrophotometry using samples irradiated with UVB lamp.
Results: The chemical stability of the R. kordesii root extract gel was determined according to
the concentration of R. kordesii extracts at different storage temperatures (5, 25 and 45 C)
for 3e4 months. It is screened for in vitro sun protection factor in the R. kordesii extract and
of its gel formulation and determines Photostability of the isolated R. kordesii extract and
SPF.
Conclusion: This study has shown that the R. kordesii petal extract gel is stable for at least 3e4
months when stored at 5 and 25 C. It is essential for collection of similar data for different
plants and their flowers, as well as other parts. This proved activity of plant showed its
importance and prophylactic utility in anti-solar formulation. This will be a better, cheaper
and safe alternative to harmful chemical sunscreens that used now a days in the industry.
