[Objective] To study chemical composition of volatile oils from underground part of Origanum vulgare L. [Methods]Volatile oils were exacted by the steam distillation( SD) method,chemical components of volatile oils were analyzed and identified by gas chromatographymass spectrometry( GC-MS) method,and relative percentage content of chemical composition was calculated by the peak area normalization method. [Results]29 kinds of chemical compounds were identified in volatile oils from underground part of Origanum vulgare L,accounting for 98. 97% of total volatile oils; among these 29 kinds of chemical compounds,10 were the first time report. [Conclusions]Apart from containing antibiotic composition as aerial part,the underground part of Origanum vulgare L also contain many fatty acid chemical compounds;such substances have strong antioxidant activities and should not be neglected,and have certain medicinal value.
