Note: Antioxidant and Antibacterial Activities of Rosa Damascena Flower Extracts

Abstract

Rosa damascena Mill. is one of the most important Rosa species for the flavour and fragrance industries. The high amount of residues of spent flowers after steam distillation and the potential use of their essential oils as natural antioxidants and antimicrobials lead to determine the antioxidant and antibacterial activities of fresh and spent Rosa damascena flower extracts. The total phenolic contents were 276.02±2.93mg gallic acid equivalent (GAE)/g in FF (fresh flower) extract and 248.97±2.96mg GAE/g in SF (spent flower) extract. FF and SF extracts showed 74.51±1.65 and 75.94±1.72% antiradical activities at 100ppm. The antioxidant activity of FF extract (372.26±0.96mg/g) was higher than that of SF extract (351.36± 0.84mg/g). Antibacterial activity of the extracts was determined by the agar diffusion method against 15 species of bacteria: Aeromonas hydrophila, Bacillus cereus, Enterobacter aerogenes, Enterococcus feacalis, Escherichia coli, Escherichia coli O157:H7, Klebsiella pneumoniae, Mycobacterium smegmatis, Proteus vulgaris, Pseudomonas aeruginosa, Pseudomonas fluorescens, Salmonella enteritidis, Salmonella typhimurium, Staphylococcus aureus and Yersinia enterocolitica. Statistical differences among bacteria were significant at p 0.05. Both extracts were effective against all the bacteria except E. coli O157:H7, although the FF extract was more effective than the SF extract. FF and SF extracts showed the strongest effects against S. enteritidis and M. smegmatis, respectively.

Evaluation, Genetic Diversity, Recent Development of Distillation Method, Challenges and Opportunities ofRosa damascena: A Review

“…In addition to its perfuming effects, it was reported that the rose oil, rose flower extracts possessed a wide range of health beneficial activities, such as antibacterial 12,46,47 , antioxidant 13,14,48 , anti-infective and antiinflammatory properties 12,49 , anti-convulsant 50 and anti-HIV 11 . The extract of R. damascena induces the neurite outgrowth and inhibits the A β (25-35)-induce atrophy 51 .…”

“…Rosa damascena has many culinary uses as a flavour additive. By-product of rose oil extraction can be utilized as an antioxidant and antibacterial agent in food industry 14 . Rose water and powdered roses are used in middle and eastern cooking.…”

“…This plant was originally brought to Europe from Damascus that is why it is called Damask rose 9,10 . Besides its application in aromatic industries, some valuable characteristics of Damask rose oil such as anti-HIV 11 antibacterial 12 and antioxidant 13,14 activities have been reported recently. The worldwide demand for high quality rose oil is expected to increase in future.…”

Chemical composition analysis of rose water samples from Iran

“…The clinical properties of rose water have been reported to provide relief from toothache, aphthous lesions, and gingival and throat inflammation (Norman, 1963). It has been used as a remedy for gastrointestinal complications (Claus et al, 1970), acne (Sharma & Jain, 2013), bacterial infections (Ozkan et al, 2004), and gastric and duodenal spasms (Sharma & Jain, 2013).…”

Seasonal changes in leaf and twig antioxidant systems in Damask rose (Rosa damascena Mill.)

“…is an important Rosa species, which are known economically for their strong fragrance, oil production and their medicinal properties (Mahmood et al, 1996;Ardogan et al, 2002;Achuthan et al, 2003;Basim and Basim, 2003;Ozkan et al, 2004). In recent years, antioxidant, antibacterial and antimicrobial activities of essential oil R. damascena have been demonstrated (Achuthan et al, 2003;Ozkan et al, 2004). Antioxidants are compounds that can delay/inhibit the oxidation of lipids or other molecules by inhibiting the initiation or propagation of oxidative chain reactions (Velioglu et al, 1998) or alternatively scavenging the free radicals generated during oxidative destruction.…”
