Immortelle (Helichrysum italicum (Roth) G. Don), belonging to the family of Asteraceae, is typically a Mediterranean plant that has a long-lasting medicinal and pharmaceutical use. The aim of this paper was to emphasise the importance of standardising procedures, as well as defining the value range within which the parameters for assessing the quality and purity of essential oils, hydrolates, and macerates should be, considering the growing commercial interest in these preparations. Quality testing is important to determine the safety, but also the effectiveness of the application of immortelle essential oil, hydrolate, and macerate, which also opens the possibility of their wider use in the pharmaceutical, food, and cosmetics industries. Determination of relative density, refractive index, acid value, pH value, turbidity, and essential oil content has already been used as a standard for determining the quality of officinal essential oils in European Pharmacopoeia. The introduction of standardised procedures for testing the quality and purity of immortelle essential oil, hydrolate, and macerate would help better analytical control of these preparations on the market.
Smilje (Helichrysum italicum (Roth) G. Don) je tipična mediteranska biljka iz porodice Asteraceae koja zbog svojih ljekovitih svojstava ima dugogodišnju medicinsku i farmaceutsku primjenu. Cilj ovoga rada je istaknuti važnost standardizacije postupaka kao i definiranje raspona vrijednosti unutar kojih bi se trebali nalaziti parametri koji će služiti za procjenu kvalitete i čistoće eteričnog ulja, hidrolata i macerata smilja, uzimajući u obzir sve veći komercijalni interes za te pripravke. Ispitivanje kakvoće važno je radi utvrđivanja sigurnosti, ali i učinkovitosti primjene eteričnog ulja, hidrolata i macerata smilja, što ujedno otvara mogućnost njihove šire primjene u farmaceutskoj, prehrambenoj i kozmetičkoj industriji. Određivanje relativne gustoće, indeksa refrakcije, kiselinskog broja, pH vrijednosti, mutnoće i sadržaja eteričnog ulja već se primjenjuje kao standard za utvrđivanje kvalitete oficinalnih eteričnih ulja u europskoj farmakopeji. Uvođenje standardiziranih postupaka za ispitivanje kvalitete i čistoće eteričnog ulja, hidrolata i macerata smilja pomoglo bi boljoj analitičkoj kontroli tih pripravaka na tržištu.
