Abstract

In
this study, the components of the volatile oil obtained from Laurus nobilis leaves by steam
distillation were determined using Agilent 6890 Gas Chromatography (GC) - 5975
Mass Spectrometry (MS). The antioxidant activities of different extracts of L. nobilis leaves were determined by
using DPPH (2,2-diphenyl-1-picrylhydrazyl) free radical scavenging
activity, β-carotene-linoleic acid bleaching assay and ABTS•+
(2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) cation radical
decolorization assay. Determination of the total phenolic contents of L. nobilis leaf extracts were performed
using the Folin-Ciocalteau procedure and total flavonoid contents were measured
using a spectrophotometric assay. According to the GC/MS results, 1,8-cineole
(46.16%), alpha-terpinyl acetate
(10.62%), alpha-pinene (6.27%),
terpinen-4-ol (5.07%) and sabinene (4.99%) were found to be the major compounds
in volatile oil. The obtained volatile oil was used to make skin care lotion.
Stability tests and organoleptic analyses of final product were performed after
1, 5, 30 and 90 days of production. The highest amounts of total flavonoid
content were found to be 5.48 ± 0.65 and 8.60 ± 0.12 µg QEs/mg in ethyl acetate
and ethanol extracts, respectively. The highest amounts of total phenolic
compounds were found to be 54.42 ± 0.14 and 25.32 ± 0.10 µg PEs/mg in ethyl
acetate and ethanol extracts, respectively. According to the results of ABTS•+,
DPPH and β-carotene linoleic acid assays, ethyl acetate extract was
found to be the most active extract (24.98±0.87 µg mL-1, 75.65±0.77
µg mL-1 and 19.32±1.04 µg mL-1).
