Study on Quality of Damascus Rose Extracts Obtained by Different Processes
Damascus rose extracts were prepared using different extraction processes,and the efficacy of the different extracts was evaluated by analyzing DPPH scavenging rate,tyrosinase inhibition rate,yield of prepared essential oils and essential oil quality.Using water distillation ex-traction process to prepare fine pure dew,distillation of fine pure dew to get fuzzy pure dew,heat pump drying extraction process to prepare bud water,detecting the DPPH radical scavenging rate and tyrosinase inhibition rate of the extracts of different processes;different rose extracts will be prepared by distillation to collect the essential oils of roses,and detecting the content and quality of the essential oils of the different extracts by GC.The results show that pod water had the highest DPPH scavenging(49%),tyrosinase inhibition(69%),and essential oil yield(0.09‰),with 42%,64%,and 0.07‰ respectively for Boutique Pure,and 41%,52%,and 0.052‰ respectively for Fouquet Pure.In summary,the best efficacy of rosa Damascus extract is obtained by heat pump drying technology process.
