Evaluation of Essential Oils and Extracts of Rose Geranium and Rose
Essential oils (EOs) and extracts of rose geranium (Pelargonium graveolens) and petals of rose (Rosa damascena) have been fully characterized in terms of composition, safety, antimicrobial, and antiviral properties. They were analyzed against Escherichia coli, Salmonella enterica serovar Typhimurium, Staphylococcus aureus, Aspergillus niger, and Adenovirus 35. Their toxicity and life span were
The only component of the rose plant that extracts oil is the petals. b) Roses have a low oil content by nature. c) Hand-harvesting is required for roses. d) Roses must be picked as soon as the sun rises. e) The rose petals must be distilled the same day they were picked. f) The supply of roses is unpredictable. g) It requires special storage

Evaluation of Essential Oils and Extracts of Rose Geranium and Rose
Fresh rose petals were dried for 1 day and 2 kg of plant material were extracted for 35 days, at a temperature of 22−27 °C, in 40 L of water containing 15% v/v ethanol. Fresh geranium leaves were dried for 8 h and then 0.2 kg of plant material were extracted for 30 days, at a temperature of 22−27 °C, in 40 L of 38% v/v aqueous ethanol.
A comparative study of rose oil obtained through traditional technology and extracts obtained using supercritical CO 2 and R134a shows that the chemical composition of the extracts was dominated by 2-phenylethyl alcohol (56.6% in the subcritical sample and 46.7% in the supercritical one), while the main aroma constituents were found substantially higher in the oil [48,49].
Therapeutic efficacy of rose oil: A comprehensive review of clinical
Rose oil is the essential oil extracted from the petals of Rosa species especially R. damascena and R. centifolia. Some historical evidence shows that rose oil is originated from Greece (Zargari, 1992 ). Currently, the main producing countries of this essential oil are Bulgaria, Turkey, and Morocco.
In present studies, through solvent extraction, Rosa damascena produced 39 g of concrete oil, which is 0.19% on petal weight basis. Rosa centifolia produced 30 g (0.15%) of concrete oil. Rosa
Technologies for extraction of oil from oilseeds and other plant
The traditional methods of oil extraction are exhaustive and have low efficacy, while conventional method of mechanical pressing is simple and involves low cost but considered as an inefficient method because of low oil recovery when compared with chemical extraction methods. Due to higher oil recovery and economic gains, chemical methods of
Niger oil cake is a valuable source of protein, with a CP content varying between 22 and 42% of DM. The oil content depends on the extraction process: it is in the 7-14% DM range for mechanically extracted cake, and lower than 4% for solvent-extracted meal. Niger oil cake is rich in fibre, with a large variability: NDF ranges from 22 to 51% of DM.
