Chemical composition, antioxidant and the possible use as skin-care ingredient of clove oil (Syzygium aromaticum (L.) Merr. & Perry) and citronella oil (Cymbopogon goeringii) from China

摘要

Clove oil and citronella oil from China were selected to evaluate their potential as skin-care ingredients. The gas chromatography-mass spectrometry (GC-MS) results showed that the main component of clove oil was eugenol, while citronellal was the main compound of citronella oil. Clove oil exhibited prominent free radical scavenging activities (IC_(50): 58 μg/mL for O2~- and 8.5 ug/mL for ABTS~+) and strong inhibitory effect on lipid peroxidation, whilst citronella oil showed weaker antioxidative activities (IC_(50): 150 ug/mL for O2~- and 500 ug/mL for ABTS~+) and lipid peroxidation inhibitory efficiency. In addition, both oils revealed dose-dependence in protecting bovine serum albumin against UV-TiO2-NO2~- induced protein oxidation and tyrosine nitration injury. This study suggests that both clove oil and citronella oil could be used as new source of skin-care ingredient in the cosmetic industry.
