Methods: After making the water of pandan leaves extract, a phytochemical test was done to determine bioactive compounds, such as tannin, alkaloids, flavonoids, and polyphenols which has anti-microbial properties. In order to determine its food preservatives capabilities, Total Plate Count and Number of Mold was used on a traditional food called Putu Ayu.
Results: Pandan leaves extract contain bioactive compound like tannin, alkaloids, flavonoids, and polyphenols.
