تركيبات تشكيل دهنده اسانس گياه Stachys spectabilis

Composition of the essential oil of Stachys spectabilis Choisy ex DC

در اين كار اسانس گونه سنبله تماشايي با روش تقطير با آب جدا‌سازي شد و اجزاي تشكيل دهنده اسانس به كمك دستگاه GC و GC-MS مورد بررسي كمي و كيفي قرار گرفت و 42 جزي شناسايي شد. در ميان اجزاي شناسايي شده تركيبات: Germacrene D (26.7%), Pulegone (4.9%), Cis-(B)-Farnesene (14.8%), B- Bisabolene (2/4%). Epi-(?)- Bisabolol (10.2%), Isoverbenyl acetate (3%), بيشترين غلظت را داشتند. بررسي‌ تركيبات شناسايي شده (1/93%) اسانس گياه Stachys spectabilis نشان مي‌دهد كه منو‌ترپنهاي اكسيژن‌دار و هيدروكربن بترتيب 87/18% و 15/1%، سسكويي‌ترپنهاي اكسيژن‌دار و هيدروكربن بترتيب 58/17% و 85/50% از تركيبات شناسايي شده را تشكيل مي‌دادند و مابقي (69/4%)، تركيبات اكسيژن‌دار غير‌ترپني بودند. مجله زيست شناسي دانشگاه آزاد اسلامي واحد گرمسار،1387، دوره3، شماره1،28-23

Abstract: The essential oil composition of S. spectabilis Choisy ex DC. has been investigated by hydrodistilation method and GC and GC/MS; 42 compounds were identified, representing 93/1% of the essential oil, which was particularly rich in monoterpenes (20/2%) and sesquiterpenes (68/43%). Among the monoterpene fractions, oxygenated compounds were present in percentages (18/87%) as compared with the hydrocarbons (1/15%) and in sesquiterpenes, oxygenated and hydrocarbon compounds were present in percentages (17/58% and 50/85%, respectively), which the major components were Germacrene D (26.7%), Cis-(B)-Farnesene(14.8%), Epi-(?)-Bisabolol(10.2%), Pulegone(4.9%), Isoverbenyl acetate(3%), B- Bisabolene(2/4%).
