摘要:
The fruit pulp essential oil of wood apple (Feronia limonia) was studied for its chemical constituents, in vitro antioxidant and antimicrobial activities. Totally, 50 constituents were identified by GC and GC-MS analyses and thymol (52.22%) was identified as the major chemical compound. The antioxidant activity showed that the essential oil had good scavenging potential viz. DPPH center dot radical (IC50 = 41.35 mu g/ml), H2O2 (IC50 = 45.49 mu g/ml), O-2(center dot-)(IC50 = 30.86 mu g/ml), OH center dot (IC50 = 25.05 mu g/ml) and ABTS(center dot+) (IC50 = 30.28 mu g/ml). The antimicrobial activity showed that Staphylococcus aureus (26.2 +/- 1.32 mm; MIC = 31.25 mu g/mL) and Bacillus cereus (24.6 +/- 1.15 mm; MIC = 62.5 mu g/mL) were the most sensitive organisms and also moderate activity was recorded against all the fungal strains tested. The present study suggests that the wood apple essential oil can be considered as a new and potential source of natural antioxidant and antimicrobial agent. (c) 2013 Elsevier B.V.
