Influence of Harvest Time, Method of Preparation and Method of Distillation on the Qualitative Properties of Organically Grown and Wild Helichrysum italicum Immortelle Essential Oil
The results of this work showed that the qualitative properties of the essential oil were influenced by the cultivation type, harvesting time, preparation method and distillation method. A higher yield (0.21% ± 0.03) of essential oil was obtained from wild immortelle whereas a better utilization rate (0.38% ± 0.09) of essential oil was obtained from the organically grown immortelle. It was also found that a higher yield of essential oil was obtained from the summer harvest (0.19% ± 0.01) and a higher utilization rate from the autumn harvest (0.33% ± 0.13) with the industrial scale distillation and shade drying. In general, better qualitative properties of immortelle essential oil were obtained from wild immortelle, which was confirmed by a chromatographic analysis and better content of γ- curcumene (16.64% ± 0.30) and neryl acetate (8.15% ± 0.19) and other constituents except α-pinene where organically grown had a higher share (24.27% ± 0.97).
