Antioxidant activity of volatile compounds from Syzygium aromaticum (L.) leaves

Abstract

Syzygium aromaticum (L.) leaf essential oil have been identified as antioxidants. This study aimed to determine the volatile compounds and antioxidant activities of Syzygium aromaticum (L.) leaf essential oil. Syzygium aromaticum (L.) leaves were extracted by steam distillation. The identification of volatile compounds was done by Gas Chromatography Mass Spectroscopy (GC-MS). DPPH test was used to evaluate the sample's antioxidant activity. The results provide information that the extract have 15 of volatile compounds from Syzygium aromaticum (L.) leaf essential oil. Moreover, DPPH test has identified a very strong antioxidant by IC50 values was 8.224 μg/mL.
