Sažetak
Rose water is the hydrosol portion of the distillate of rose petals, a by-product of the production of rose oil. The goal of this study was to investigate the impact of petal and leaf mass during distillation on chemical composition of hydrosols. The highest antioxidant activity (94.95 µmol trolox/mL) had hydrosol obtained after distillation of 80 kg of petals. The same hydrosol had the highest contents of beta-citronellol (13.24%), linalool (6.92%) and geraniol (8.41%). Hydrosol obtained after distillation of 60 kg of petals had the highest content of 2-phenylethanol (75.96%). Interestingly the hydrosol obtained after distillation of 60 kg of leafs had different volatile profile with 4, 4, 8-trimethyltricyclo [6.3.1.0 (1, 5)] dodecane-2, 9-diol as major volatile (19.15%) followed by linalool (15.99%), alpha terpineol (12.50%) and tricyclo [4.2.1.1 (2, 5)] decan-9-ol (9.89%).
