20.500.12556/RUL-91513 Dejavniki, ki vplivajo na vsebnost in kakovost eteričnega olja damaščanske vrtnice (Rosa Damascena Mill.) Factors affecting the composition and quality of damask rose (Rosa damascena Mill.) essential oil Damaščanska vrtnica (Rosa damascena Mill.) velja za kraljico med vrtnicami. Razširjena je po celem svetu, še posebej v Bolgariji, Turčiji, Maroku, na Kitajskem in v Iranu. Je hibridna vrtnica, nastala s križanjem treh sort vrtnic. Njen izvor ni popolnoma znan, zato se zgodovinski opisi med avtorji nekoliko razlikujejo. Damaščansko vrtnico sadimo v okrasne namene, predvsem pa se jo zaradi prijetnega vonja goji za uporabo v parfumski, kozmetični in živilski industriji ter za medicinske namene. S parno destilacijo iz nje pridobivajo eterično olje, kot stranski produkt pa rožno vodo. Njeno eterično olje velja za eno izmed najdražjih eteričnih olj na svetu. Glavne sestavine eteričnega olja so beta-citronelol, nerol, fenil etil alkohol, geranil, heptadekan, nonadekan, geraniol, metil evgenol, evgenol in geranil acetat. Značilni vonj pa prispevajo beta-damaskon, beta-damascenon in beta-ionon. Na vsebnost in kakovost eteričnega olja damaščanske vrtnice vpliva veliko dejavnikov, najpomembnejši so: stopnja razvoja cvetnega brsta, datum in čas obiranja, skladiščenje in fermentacija, pogoji destilacije, rez, genotip in genski inženiring ter zdravstveno stanje rastlin. Da dobimo eterično olje najboljše kakovosti in s primerno količino sekundarnih metabolitov pa je treba upoštevati tudi pravila dobre agronomske prakse.
