Variation of Immortelle (Helichrysum italicum (Roth) G. Don) essential oil composition depending on method of processing and time of harvest
Immortelle (Helichrysum italicum /Roth/ G. Don) is a perennial subshrub that belongs to Asteraceae family, widespread in the Mediterranean. It is used in cosmetic and pharmaceutical preparations due to its medicinal properties. In recent years immortelle has become the most economically valuable medicinal plant in Croatia. It is both wild harvested and grown commercially. In order to obtain essential oil with desirable composition, which meets commercial demands, it is necessary to investigate the optimal method of processing immortelle as well as the optimal harvesting time. We conducted a preliminary study on a small number of samples to determine the differences in chemical composition of essential oils obtained from fresh and dry biomass. The investigations were carried out on four natural populations of immortelle from Croatia. The essential oil was obtained by hydrodistillation, and its content and composition was analysed by gas chromatography and mass spectrometry GC-MS. The results showed differences in essential oil content and composition between the fresh and dryed biomass. To determine the influence of the harvest time on the essential oil composition, immortelle essential oil was analysed by GC-MS in the plants shortly before flowering and in the stage of full blossom. The results showed that the stage of harvest plays important role in variation of essential oil composition in immortelle.
