Abstract

Smilje (Helichrysum italicum) (Roth) G. Don je mediteranska biljka koja se zbog svojih ljekovitih svojstava koristi u farmaceutske i kozmetičke svrhe. U ovome radu uspoređeni su dalmatinski i kontinentalni hidrolati smilja (n=6) na temelju mjerenja različitih parametara: relativne gustoće koja je bila između 0,9850 i 1,0750, indeksa refrakcije koji je iznosio između 1,3328 i 1,3330, kiselinskog broja koji je bio u rasponu između 0,540 i 0,589 mg KOH/g, pH koji je bio između 3,43 i 4,66, mutnoće koja je bila između 1,18 i 5,20 NTU i sadržaja eteričnog ulja koji je iznosio između 0,07% i < 0,14%. Budući da nema referentnih vrijednosti ovih parametara za hidrolate, izmjerene vrijednosti su uspoređene s dostupnim podacima za eterično ulje smilja. Provedena ispitivanja nisu pokazala značajnije razlike u izmjerenim fizikalnim i kemijskim vrijednostima između dalmatinskog i kontinentalnog hidrolata smilja. S obzirom na sve veću primjenu hidrolata u kozmetičke i farmaceutske svrhe potrebno je uvesti i standardizirati metode za utvrđivanje njihove kvalitete i čistoće.

Abstract (english)

Immortelle (Helichrysum italicum) (Roth) G. Don is a Mediterranean plant that is used for pharmaceutical and cosmetic purposes due to its medicinal properties. In this thesis, Dalmatian and continental immortelle hydrolates (n=6) were compared based on measurements of different parameters: relative density which was between 0.9850 and 1.0750, refractive index which was between 1.3328 and 1.3330, acid number which was between 0.540 and 0.589 mg KOH/g, pH which was between 3.43 and 4.66, turbidity which was between 1.18 and 5.20 NTU and essential oil content which was between 0.07% and < 0.14%. Since there are no reference values of these parameters for hydrolates, the measured values were compared with the available data for immortelle essential oil. The obtained results did not show significant differences in the measured physical and chemical values between Dalmatian and continental immortelle hydrolates. Considering increasing use of immortelle hydrolates for pharmaceutical and cosmetic purposes, it is necessary to introduce and standardize methods for determining their quality and purity.
