Abstract :
Sterculia Populifolia is commonly used as the ingredient of traditional herb in Timor Island, East Nusa
Tenggara, Indonesia. It contains flavonoid which roles as antioxidant. This flavonoid can be sunblock due to
the existence of chromophore which commonly gives color to plants. This study aimed to determine the
activity of antioxidants and sunblock through the value of Sun Protection Factor (SPF) from Sterculia
Populifolia extract-based cream and cream preparation extract. This cream was formulated into four
formulas; extract concentrate 0% (F0), 1% (F1), 3% (F2) and 5% (F3). The result showed that the whole
formula of cream preparation filled the physical stability parameter. F3 cream had IC50 79.179 ppm value
while SPF had 5.6 value higher than F1 and F2. The smaller the IC50 value, the bigger antioxidant activity and
SPF increased.
