RESUMO: Schinus terebinthifolius Raddi: Composição química, propriedades biológicas, e toxicidade. Schinus terebinthifolius Raddi é uma planta medicinal conhecida no Brasil como "aroeira da praia", utilizada na medicina popular como antitérmica, analgésica, depurativa e no tratamento de doenças do sistema urogenital. Por outro lado, a literatura científica relata que essa planta apresenta atividade antimicrobiana, anti-inflamatória, e antiulcerogênica. Essa revisão trata das principais propriedades biológicas e efeitos toxicológicos da aroeira da praia, além de uma abordagem sistemática acerca dos compostos que já foram encontrados nessa espécie, estando a maioria deles presente nos óleos essenciais.Palavras Chave: Schinus terebinthifolius, Anacardiaceae, componentes químicos, propriedades biológicas. ABSTRACT: Schinus terebinthifoliusRaddi is a medicinal plant known in Brazil as "aroeira da praia", which has been used in popular medicine as antipyretic, analgesic, depurative and in the treatment of diseases of the urogenital system. On the other hand, the scientific literature has reported that this plant has antimicrobial, anti-inflammatory and antiulcerogenic activity. This review addresses the main biological properties and toxicological effects of "aroeira da praia", in addition to a systematic approach of the compounds that were already found in this species, the great majority of which is present in the essential oils.

Ferulic acid (4-hydroxy-3-methoxycinnamic acid) is a phytochemical constituent from the polyphenols group commonly found in whole grains, spinach, parsley, grapes and rhubarb. It has been widely applied in skin care formulations as photoprotective agent and delayer of cutaneous photoaging processes. This work aims to establish a protocol to the development of cosmetic formulations using thermoanalytical techniques (TG/DTG and DSC) and Pearson's correlation by FTIR data, in order to evaluate the compatibility between ferulic acid and excipients used in skin care formulations. The results obtained from the thermoanalytical techniques indicated compatibility between ferulic acid and the following excipients: passion fruit seed oil, Carbopol Ò Ultrez 30, EDTA, Crodabase CR2 Ò , Crodamol TM GTCC and Dow Corning Ò RM 2051. Nevertheless, the analysis also demonstrated the possibility of some interaction between ferulic acid and the following excipients: glyceryl stearate, Rapithix Ò A-60 and Optiphen Ò . To validate these results, it was demonstrated by Pearson's correlation that passion fruit seed oil, Carbopol Ò Ultrez 30, EDTA, Crodabase CR2 Ò , Crodamol TM GTCC, Dow Corning Ò RM 2051, glyceryl stearate and Rapithix Ò A-60 do not have any incompatibility that may compromise ferulic acid properties. Finally, it was also proved a meaningful incompatibility between ferulic acid and Optiphen Ò using Pearson's correlation. Thus, it is not recommended to use Optiphen Ò in the development of cosmetic formulations to carry ferulic acid.
