Formulasi dan uji aktivitas antioksidan losio ekstrak metanol alga hijau caulerpa racemosa
Abstrak: Caulerpa racemosa is
one type of green algae has the ability to defend againts radiation of
ultraviolet. Lotion is a liquid or semiliquid preparation containing one or
more active ingredients with a suitable vehicle and provides a comfortable and
good feel to the skin. The aim of this research was to obtain the optimum
formula based on organoleptic testing,viscosity,pH,flow type,globule of
dispersion and antioxidant activity.the method of this research is experimentally
which done by making some design of lotion formulation from methanolic extract
of green alga caulerpa racemosa. Stability of lotion was evaluated include
organoleptic testing,pH measurement,type of emulsion,viscosity,flow type,size
and distribution of globule dispersion. Determining of effectiveness of lotion
as an antioxidant by IC50 value with UV-Vis spectrophotometry method. Result of
this research collected and processed statistically with the completely
randomized design method,then made the discussion and taken the
conclusion.based on the evaluation,it was found that lotion containing 0.75%
methanolic extract of caulerpa racemosa green algae (formula III) had the most
optimum pharmaceutical stability. And the three lotion formulas have antioxidant
activity
