Study on High Performance of the Separation on Six Low Content Components from Camphor Tree Essential Oils and the Antioxidant Properties
A method of staged vacuum distillation combined with column chromatography was developed on highly performance separation of six low content components with the initial content less than 10.0％to more than 80.0％from camphor tree essential oils,in which the six compounds included limonene(93.2％),bornyl acetate(87.5％),trans-nerolidol(85.8％),β-caryophyllene(91.1％),4-terpineol(92.6％),and α-terpineol(87.2％)were obtained by flash chromatography column with the yield of 36.0％,14.0％,11.0％,21.0％,38.0％,and 10.0％,respectively.Furthermore,the antioxidant properties of each fraction and reference compoundswere evaluated.The IC50 values of bornyl acetate,trans-nerolidol,4-terpineol and α-terpineol fraction were 96.6 mg/mL,87.6 mg/mL,73.6 mg/mL,and 105.4 mg/mL,respectively,which exhibited superior antioxidant properties compared to corresponding reference compound(monoterpenes).The IC50 values of limonene and β-caryophyllene fraction were 66.2 mg/mL and 48.5 mg/mL,respectively,which exhibited lower antioxidant properties than the corresponding reference compound.
