Study of volatile oil components of petal and herbal and chemical composition extracted of seed oil in Borage by Cold Press method

Background: Regarding a few reported studies about the volatile oil component of petal, herbal and component of seed oil of Borage. This research carried out to analyze and identify the volatile oil in herbals, petals, and seed oil compositions of Borago officinalis L. in Lorestan province. Materials and Methods: Extraction of essential oil from petals carried out using steam distillation by Clevenger apparatus. The new SPME-GC/MS method was used for extraction and identification of volatile oil compounds in the herbal of borage. The oil of the seeds was extracted using a Cold-press method. The identification of chemical composition of extracted oil was carried out by GC/MS apparatus. Results: In petals of Borage only Carvacerol component, and in the herbal of Borage three components Carvacrol, Bisabolone oxide and 2-Phenylethyl benzoate, extracted and identified respectively. In the seed oil of Borage 16 different components were separated and identified. The following components had the highest amount in seed oil: Hexadecane, N, N-dimethylethanolamine, Beta-d-glycoside, 3, 6-glucurono-methyl, Benzaldehde, 4-methyl 3-Hydroxytetrahydrofuran, Hexadecanoic acid, Heptanoic acid, Gamma butyrolactone and Ethyl octadec-9-enoate. These components contain 63.4% of all components in Borage seed oil and the 7 residual components only 9.5% all of the components in borage seed oil. Also one unknown (27.1%) component identified. Conclusion: Based on the results obtained from this research the volatile oil has formed a few percentages of the Borage chemical composition, as well as cold Press method was found to be rapid and simple for identification of seeds oil components.
