Rosella is a plant which is used as an antioxidant. The content that acts an antioxidant is rutin compunds. The purpose of this study to determine the effect of propylene glycol (PG) and Oleic Acid (OA) enhancers against the properties and stability physical and the antioxidant activity of lotion. Antioxidant activity test was done by 2,2-Diphenyl-1-picryhidrazil (DPPH) method and then calculated the percentation its inihibis. To get the effect of antioxidant, the formulation of lotion was needed with the compotition addition enhancers of PG and AO : formulation I (without enhancer), formula II (AO 100%), formula III (AO 50% and PG 50%), and formula IV (PG 100%). The study results showed that the addition of enhancer on the lotion has increased activity antioxidant where the value of precentage inhibisi from formulation I to formulation IV were 15,625%, 17,7319%, 24,778%, 25,719% respectively. Moreover, extract etanol of purple rosela flower was also have properties and physic stability better after done the physic stability test includes organoleptic observations, hogenecity, pH test, dispersion and adhesion.
