The phytochemical screening and antioxidant potential of cinnamomum javanicum blume leaves from Central Kalimantan

Abstract

Background: Sintok lancang (Cinnamomum javanicum Blume.) is one of the typical plant of Central Kalimantan, which has not been widely studied. Local people use leaves of C. javanicum to treat various diseases, like diabetes and skin diseases. Based on this, it is necessary to do preliminary study to know phytochemical content and antioxidant potential that may be contained in this plant. Methods: C. javanicum leaves were extracted using percolator with 96% ethanol. The extract was tested for qualitative phytochemical with standard procedures, while the antioxidant test was carried out using 1,1-diphenyl-2-picrylhydrazyl (DPPH) method with quercetin as standard and ferric reducing antioxidant power (FRAP) with trolox as standard. Results: The result showed ethanolic extract of C. javanicum leaves qualitative phytochemical contained alkaloid, flavonoid, tannin and steroid. Antioxidant activity test showed leaves of C. javanicum with DPPH method IC50= 26.99±0.27 ppm and antioxidant activity with FRAP method 779.73±19.66 µmoltrolox/g. Conclusion: It can be concluded that C. javanicum leaves have potential high antioxidant activity was tested with DPPH and FRAP method. Furthermore need further research, especially to determine specific compound of C. javanicum leaves.
