بررسی روش و میزان اسانس گل محمدی در کارخانجات در مقایسه با روش آزمایشگاهی (نیمه صنعتی)

‭Rosa damascena Mill. can be cultivated in different parts of Iran. It can produce rose water and essential oils in large- scales. Essential oils can used in Food, perfumery and In this research, 18 samples were prepared ITom different traditionaly small factories and big factories to compare with laboratory scales essential oils. Samples were analyzed by GC and GCIMS. Samples from factories were collected in June 2005. The main constituents in Ghatran Goal Co. (sample 1) were n-nonadecane (33.1%); geraniol (14.6%), n-heneicosane (13.2%); Mah goolab Co. (sample 2) were n. nonadecane (38.5%); n-heneicosane (16.1%); n- hexadecanol (12.2%), Iran goolab Co. (sample 3) were n-nonadecane (39.3%); n-heneicosane 16.5%); n- hexadecanol (12.5%); Goolab Haghighat Co. (sample 4) were n-nonadecane (42.2%); n-heneicosane (15.9%); n- hexadecanol (11.6%), factories yields varied between 0.01 upto 0.02% . The main constituents in traditional factories like Ashk gool (sampleS) were n-nonadecane (49.2%); n- hexadecane (17.2%); geraniol (11%), Abshar Niasar (sample 6) were n-nonadecane (50.5%); n- hexadecanol (16.1%); n- heptadecanol (7.6%), and another ITom Niasar (sample 7) were n-nonadecane (33.8%); n-heneicosane (20.7%); n- hexadecanol (12.2%); in Ghazan village from Kashan (sample 8) were n-nonadecane (44.7%); n-heneicosane (16.6%); n- hexadecanol (11.9%); Goolab Tooba (sample 9) were n-nonadecane (43.1%); n-heneicosane (16%); n- hexadecanol (11.3%); Borzok (sample 10) were n-nonadecane (35.4%); n-heneicosane (18.4%); n- hexadecanol (12.6%); from kshlaj village Sarcheshmeh (sample 11) were n-nonadecane (36.7%); n-heneicosane (20.5%); n- hexadecanol (13.7%); and another sample from same village from Gholsanhay e Nashlaj (sample 12) were n-nonadecane (35%); n-heneicosane (19.5%); n- hexadecanol (14.9%); from Karnoo village two samples were (sample (3) contained n-nonadecane (32%); n-heneicosane (17.9%); methyl hexadecanoate (12.8%), and (sample 14) were n-nonadecane (34.4%); n-heneicosane (19.9%); n- hexadecanol (15.2%), Josheghan e Kashan (sample 15) were n-heneicosane (18.4%); n-nonadecane (12%); n- hexadecanol (4.8%), vezoan e Kashan (sample 16) were n-nonadecane (33%); n-heneicosane (18.1%); mehyl hexadecane (12.9%), factories yields varied between 0.01 upto 0.02% .Laboratory essential oils samples were extracted by two plan which designed inResearch Institued of Forests and Rangelands by authors which were named plan1‬ص ‭and plan-2. The main isolated constituents in plan-I were geraniol (21.8%), n-nonadecane (21.3%); citronellol (12%), with yield of (0.015%) and in plan-2 were n-nonadeeane (21.8%) getaniol (19.1%). Citronellol (15.%) with eield of (0.023%).‬
