saffron as a natural UV- absorbing agent

Golmohammadzadeh SH. et al evaluated saffron for its anti-solar activity. The pollens of the saffron were dried and powdered in a grinder. The experimental formulation included a homosalate (8%) lotion reference, lotions with 2,4 and 8% or grinded saffron, and the control lotion base without saffron. The locations containing saffron were prepared like homosalate lotion reference according to FDA. The sun protected factors (SPFs) of the formulations were deremined by an in vitro spectrophotometry method. The results of this study indicated that saffron can be used as a natural UV-absorbing agent.
