Sinteza in olfaktorno vrednotenje derivatov cinamil alkohola in cimetove kisline = Synthesis and olfactory evaluation of cinnamyl alcohol and cinnamic acid derivatives : univerzitetni študijski program KozmetologijaBorošak, LaraCinamil alkohol in cimetova kislina sta naravni spojini, ki se uporabljata v parfumski in kozmetični industriji ter farmaciji. Najbolj znana je njuna prisotnost v cimetovcu, ki spada v družino ... lovorovk (Lauraceae). Cinamil alkohol in cimetova kislina sta sestavini eteričnega olja cimeta, ki ga pridobivajo iz listov, lubja in korenin. Pri standardnih pogojih je cinamil alkohol bela do rumenkasta kristalna trdna snov, s prijetnim, cvetličnim in sladkim vonjem ter okusom po cimetu. Cimetova kislina pa je bela kristalna organska spojina, katere vonj spominja na med. V naravi so cimetova kislina in njeni derivati zelo razširjeni, a jih večinoma najdemo v zelo nizkih koncentracijah. Sintezno pridobljena cimetova kislina pa nastaja s Perkinovo reakcijo. Namen diplomske naloge je bil sintetizirati derivate cinamil alkohola in cimetove kisline ter nastale produkte olfaktorno ovrednotiti. Uspešno smo sintetizirali deset njunih derivatov, po strukturi estrov in etrov. Ena reakcija ni potekla. Vse produkte smo očistili s kolonsko adsorpcijsko kromatografijo, kjer smo za razvijanje kromatogramov uporabili mobilno fazo, sestavljeno iz zmesi etilacetata in heksana v volumskem razmerju 1 : 4 ter 1 : 6. Uspešnost reakcij in identiteto produktov smo preverili z instrumentalnimi analiznimi metodami, in sicer z uporabo jedrske magnetne resonance ter infrardeče spektroskopije. Nato smo končne spojine olfaktorno vrednotili z vonjalnim testom, s katerim smo preverjali prijetnost in jakost vonjav ter asociacije na druge vonje. Večina derivatov cinamil alkohola in cimetove kisline ima prijeten vonj. Povprečna ocena jakosti vonjev testiranih vzorcev ima šibek do zmerno močan vonj. Vonji niso bili konstantni in so se tekom vonjalne analize spreminjali. Pri vrednotenju vzorcev so anketiranci označili cinamil butirat, cinamil fenilacetat in cinamil heksileter kot najprijetnejše vonjave. Pri opisovanju vonjav nismo ugotovili nobenih razlik med osebami, ki parfume uporabljajo in tistimi, ki jih ne.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [L.
