Chaerophyllum libanoticum Boiss. Et Kotschy: The fruit essential oil, composition, skin-whitening and antioxidant activities

This study was aimed to evaluate the essential oil composition of Chaerophyllum libanoticum fruits and its potential uses in the cosmetic industry. The essential oil was analyzed by Gas Chromatography (GC) and Gas Chromatography-Mass Spectrometry (GC/MS) systems, simultaneously. The yield of essential oil was calculated as 0.22 % (v/w). Major components of the oil were characterized as limonene (26.7%), p-cymene (25.5%), and β-phellandrene (7.0%). In addition, antioxidant and antityrosinase activities of the essential oil were evaluated. The oil exhibited moderate antioxidant activity (TEAC). In the DPPH assay, the oil was tested at 5 mg/mL concentration, and the inhibition ratio was calculated as 31.3 ± 1.1%. At 1 mg/mL of concentration, TEAC (mmol/L) value was determined as 0.027 ± 0.008. As evidence to its skin whitening properties, the oil inhibited the tyrosinase 17.7 ± 1.6 % at 1 mg/mL.
