Abstract :

Iris, a plant belong to Iridaceae family, is a precious medicinal, aromatic and ornamental plant. Iris has been used at cure of cancer, ichors, virus and bacterial infections in medicine, and at perfumes and cosmetics due to the attractive scent of essential oil in industry. The research was conducted with the aim to determine of essential oil content and composition, resinoide and absolute of iris. The essential oil of Iris florentina was extracted by hydro distillation by using Clevenger apparatus, and resinoide and absolute were obtained by using n-hexane and ethyl alcohol, respectively. Essential oil components were identified by GC/MS (QP5050 gas chromatography/mass spectrometry). Statistically non-significant differences were observed in the fresh and dry rhizome, and statistically significant differences (p 0.01) in the resinoide and absolute of Iris florentina. In the Iris florentina, the fresh and dry rhizome essential oil resinoide were determined as 0.04 % and 0.07 % respectively, and the resinoide and absolute were obtained as 2.21% and 1.92%, respectively. The main compounds of Iris florentina essential oil, resinoide and absolute were determined as decanoic acid, ethanon, α- Iron, trans-2,6-γ-Iron, lauric acid, myristic acid, palmitic acid, 9,12 oktadecadienoic acid and hexanedioic acid bis ester. In the main components of essential oil, resinoide and absolute of iris were significant differences determined. α-iron and γ-iron contents weren’t determined in fresh rhizome essential oil that they are accepted as the most significant commercial quality criteria of iris essential oil. The highest α-Iron and trans-2,6-γ-Iron contents were obtained in dry rhizome essential oil (4.21% and 7.88%, respectively), their the lowest values were determined in resinoide (0.69% and 1.25%, respectively).
