Herbal preparation used as sunscreens is not only for enhancing the human natural appearance and immune system but also protect the skin against ageing and harmful Ultra-violet radiations. The present study involves the evaluation of sun protection factor (SPF) of the leaf part of plant Catharanthus roseus. Hydroalcoholic, ethyl acetate and methanolic leaf extract of Catharanthus roseus was prepared via soxhaltion and the total phenolic content and total flavonoid contents with sun protection factor (SPF) of all the extracts were calculated. The methanolic leaf extract showed the highest value among all i.e., 53.24 ± 0.36, 46.02 ± 0.14 and 11.02 ±0.001 value of total phenolic content, total flavonoid contents and SPF value respectively.
