Warning for the buyers

We find it important to notify the buyers that we produce helichrysum essential oils exclusively from wild-grown helichrysum.

We have noticed that cultivated helichrysum looks different from wild-grown helichrysum, and it gives oils with different chemical composition.

In the attachment you can find GC analysis from our essential oil, analysis from cultivated helichrysum  and experts opinion.

Experts opinion:

Immortelle (Helichrysum italicum) essential oil analyses

Analyses of cultivated immortelle samples indicate significant differences in sensory characteristics as well as in chemical composition of the essential oil.

Previous GC analyses of essential oil obtained by distillation of wild immortelle showed a difference in the content of individual components between samples which mostly depend on the harvesting time. Samples collected in June and early July gave essential oil lower in α-pinene (21%) and a higher in sesquiterpenes in comparison with samples collected in late August and later that contain about 27% of α-pinene and therefore less sesquiterpenes. This is also true for italicenes, sesquiterpenes characteristic for immortelle essential oil, because essential oil obtained from samples collected in June and early July contained 7-11% of italicenes in contrast to the samples collected in late August and later that contained 6% of italicenes in maximum. In contrast to this, angelic acid esters, which are also typical for immortelle essential oil, didn’t differ significantly depending on the harvesting time and their content in the essential oil of immortelle was 1-2.5%. The same goes for italidiones whose content in samples were 0.5-1.8%. The most abundant monoterpene ester was neryl acetate and variation in its content (4-11%) did not depend on the harvest time.

Samples of cultivated immortelle significantly differed in the sesquiterpene alcohol content because its content was greater than 5.5%, while in essential oils of wild immortelle was up to 2.5%. This had the effect on reducing the content of sesquiterpenes from which these sesquiterpene alcohols incurred. Italicenes content in cultivated samples was about 16%, which is higher than in wild immortelle samples, and the content of italidiones was not significantly different from wild immortelle value (1-1.5%). Angelic acid esters content was greater than 3%, which is also higher than previously obtained values for wild immortelle essential oil.
