Bidara leaves (Ziziphus spina-christi L.) are known for their high antioxidant activity. It can be used as an additional active component in the preparation of lip balm formula. The purpose of this research is to get lip balm formula enriched with Bidara leaf extract and determine its antioxidant activity. The antioxidant activity of Bidara leaf in ethanol extract was tested using 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay and the active component that gave the role to it was identified using GCMS (Gas Chromatography and Spectrometry Mass). The result showed that Bidara leaf extract contained a phytol component with highly strong antioxidant activity. The preparation formula of lip balm used 0, 1, 2 and 3% (w/w) of Bidara leaf extract expressed by F0, F1, F2, and F3 respectively. All lip balm products tested have met the requirements for Indonesian National Standard (SNI) 16-4769-1998 criteria encompass melting point range 53.50 – 54.50 ºC; pH value 4.43 – 4.53; homogeneous; and negative microbial contamination. The most optimum Bidara lip balm product based on general panelists preference level was F1, which content 1% of Bidara leaf extract with half-max inhibitory concentration value (IC50) of 339.23 ppm.
