Porang (Amorphallus muelleri Blume) is one type of tuber plant that has the potential to be developed in
Indonesia. Porang plants have been reported to contain chemical compounds that have antioxidant
activity. This research was conducted on the leaves of the porang plant with the aim of knowing the
antioxidant activity, characterization, and phytochemical profile of the compounds contained therein.
Compound identification and characterization were performed using standard methods, and antioxidant
activity was determined using the DPPH (1,1- Diphenyl-2-picrylhydrazyl ) method. The results of the
identification of chemical compounds showed that the ethanol extract of porang leaves contained
chemical compounds of alkaloids, flavonoids, tannins, saponins, and steroids. The results of the
examination of the simplicia characterization of porang leaves included the soluble ethanol content of
33.93%, the water soluble extract content of 17.3%, the ash content of 5.58%, the acid insoluble ash
content of 0.235% and the water content of 8%. From the results of the simplicia characterization, it
shows that the results meet the specified requirements. The results showed that the ethanol extract of
porang leaves had antioxidant activity with an IC50 value of 93.04 µg/mL, which in this case is included
in the category of strong antioxidant activity. Meanwhile, as a comparison, Vitamin C was used, which
has an IC50 value of µg/mL, which is included in the category of very strong antioxidant activity.
