Formulation And Testing Of Antioxidant Activity Of Organic Powder Mask Preparation From Bidara Leaves (Ziziphus Spina-Christi L.) Using The Dpph Method

Abstract

Bidara leaves (Ziziphus spina-christi L.) have flavonoids, tannins, saponins and alkaloids. Flavonoids are antioxidant compounds that can counteract free radicals. This study aims to determine the physical quality and antioxidant activity of Bidara Leaf (Ziziphus spina-christi L.) organic powder mask preparations which meet the physical quality requirements, namely organoleptic tests, homogeneity tests, pH tests, spreadability tests, and particle size tests, as well as antioxidant activity. The research design used was laboratory experimental. This study consisted of four formulas with varying concentrations of Bidara leaf extract as the active substance, namely F0 without extract, FI 25%, FII 30%  and FIII  35%. The data were analyzed using ANOVA statistics. The results showed that the ethanol extract of Bidara leaves (Ziziphus spina-christi L) could be formulated into an organic powder mask preparation that met the requirements for good physical quality and physical stability of the mask preparation. After testing the antioxidant activity it was concluded that the organic powder mask of Bidara Leaf extract (Ziziphus spina-christi L.) has a very strong antioxidant activity, namely in the third formula the addition of 35% extract with an IC50 value of 43,333 µg/ml.
