Chemical components and antioxidant properties of acetone extracts of four different species of Zingiberaceae

Abstract

In this report, the chemical components and antioxidant properties of the acetone extracts obtained from 4 Zingiberaceae species, including Curcuma gracillima Gagnep., Curcuma pierreana Gagnep., Globba marantina L. and Amomum biflorum Jack were investigated for the first time. A total of 142 chemical compounds were determined in 4 studied extracts using GC/MS techniques. Furthermore, the extract obtained from C. gracillima showed the strongest antioxidant effect with an IC50 value of 1.76 mg/mL, followed by G. marantina (IC50 = 2.45 mg/mL), C. pierreana (IC50 = 2.97 mg/mL) and A. biflorum (IC50 = 6.32 mg/mL).
