Chromatographic and Spectroscopic Fingerprinting of Ficus carica and Evaluation of In Vitro Antioxidant Activity
The present study was conducted to evaluate the in vitro antioxidant activity of Ficus carica, commonly known as fig. Methanol and ethanol extracts of F. carica leaves were subjected to 2, 2-diphenyl-1-picryhydrazyl (DPPH) free radical scavenging activity assay where ascorbic acid being positive control had an IC50 value of 3.98±0.26 while methanol and ethanol fractions showed an IC50 of 101.76±1.12 and 93.12±1.17 respectively exhibiting their high antioxidant potential. DPPH assay was also performed on high performance liquid chromatography (HPLC) elutions. Most active antioxidant components in ethanol extract were eluted between 17–18 min, and those in methanol were eluted over 14–15 min and upon ultra-high performance liquid chromatography-mass spectrometery (Orbitrap Liquid Chromatography-Mass Spectrometry) were identified to be 13-Docosenamide, (Z)- for ethanol and ficusin for methanol fraction. Thus, it is concluded that these two components are most probable determinants of antioxidant potential of F. carica leaf extracts. © 2021 Friends Science Publishers
