At the present time, there is a great interest in the production of sunscreens based on natural products due to the current trend for green cosmetics, as they show lesser side effects (reduced allergenic effect) and aggressions to the environment when compared to synthetic protectors. Within this perspective, a viable and low-cost alternative to combat the harmful effects of UV radiation would be to use plant extracts containing flavonoids, as they are considered capable of absorbing this radiation. The aim of the present study was to analyze the Sun Protection Factor (SPF) of the plant extracts of Matricaria chamomilla L. and Rosmarinus officinalis L.; from the in vitro spectrophotometric analysis proposed by Mansur. For this, the tinctures of these vegetables were incorporated separately in Natrosol® based gel in concentrations of 5%, 10% and 20%, and, based on this methodology, the SPF obtained were, respectively: Matricaria chamomilla L. 0.64, 1.95 and 3.43; Rosmarinus officinalis L. 1.59, 3.29 and 1.65; and when mixed 1.45, 2.67 and 1.14. Thus, it was possible to analyze that the studied plant specimens have protection against UV rays, however, this protection is not significant, since the values found were relatively low. Therefore, a positive, but not efficient, result was achieved when treated with topical protection against the sun's rays. The antagonism process was also verified when tinctures were mixed, and a decrease in SPF in high concentrations of Rosmarinus officinalis L.
