Abstract

Smilje (Helichrysum italicum (Roth) G. Don) je tipična mediteranska biljka iz porodice Asteraceae koja zbog svojih ljekovitih svojstava ima dugogodišnju medicinsku i farmaceutsku primjenu. U ovom diplomskom radu izmjereni su kemijski (kiselinski broj) i fizikalni (relativna gustoća, indeks refrakcije) parametri, pH vrijednost i sadržaj eteričnog ulja macerata dalmatinskog i kontinentalnog smilja u maslinovom ulju (n=6) u svrhu ispitivanja čistoće i kvalitete macerata smilja. Izmjerena vrijednost kiselinskog broja iznosila je između 1,71 i 2,88 mg KOH/g, relativna gustoća iznosila je između 0,905 i 0,988, indeks refrakcije je bio između 1,4691 i 1,4743. Izmjerena pH vrijednost iznosila je između 4,40 i 5,25, a sadržaj eteričnog ulja je bio od <0,08 do 0,51 %. Dobivene vrijednosti uspoređene su s referentnim vrijednostima za eterično ulje smilja i maslinovo ulje budući da referentne vrijednosti za macerat smilja u maslinovom ulju nisu dostupne u literaturi. Dobiveni rezultati pokazuju da nema značajnih razlika između uzoraka macerata dalmatinskog i macerata kontinentalnog smilja. S obzirom na sve veću upotrebu pripravaka smilja u medicinske i kozmetičke svrhe, postoji potreba za definiranjem referentnih vrijednosti kemijskih i fizikalnih parametara za procjenu čistoće i kvalitete macerata smilja.

Abstract (english)

Immortelle (Helichrysum italicum (Roth) G. Don), belonging to the family of Asteraceae, is a typically Mediterranean plant that has a long-lasting medicinal and pharmaceutical use. In this thesis, chemical (acid value) and physical (relative density, refractive indeks) parametres, pH value and essential oil content of Dalmatian and continental immortelle olive oil macerates were measured in order to investigate the purity and the quality of immortelle oil macerates. The measured acid value was between 1,71 i 2,88 mg KOH/g, the relative density was between 0,905 and 0,988, the refractive index was between 1,4691 and 1,4743. The measured pH value was between 4,40 and 5,25 and the essential oil content was from<0,08 to 0,51 %. The obtained values were compared with the reference values for immortelle essential oil and for olive oil because the reference values for immortelle olive oil macerate are not available in the literature. The obtained results showed that there are no significant differences between the samples of Dalmatian immortelle oil macerates and continental immortelle oil macerates. Considering the increasing use of immortelle preparations for medicinal and cosmetic purposes, there is a need to define the reference values of chemical and physical parameters to assess purity and quality of immortelle oil macerates.
