摘要：

The present study investigated the compositional variation and antioxidant potential of Origanum vulgare L. (subsp. vulgare) collected from three districts of Uttarakhand, India. The essential oil composition was analyzed by GC and GC/MS, and the antioxidant potential was evaluated using 2,2MODIFIER LETTER PRIME-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity, ferric reducing antioxidant power (FRAP) activity and Fe2+-ferrozine test system for iron-chelating activity methods. The analysis allowed the identification of 22-36 compounds representing 87.84-92.95% of the total essential oil. Samples S-1 and S-2 contained a high amount of sesquiterpene hydrocarbons (26.37-47.25%), while sample S-3 was rich in oxygenated monoterpenes (70.21%). The major component was (E)-caryophyllene in S-1 and S-2 samples (15.40-26.41%) and thymol (60.3%) in S-3 sample. The S-3 sample collected from the lowest altitude showed the highest oil yield and antioxidant activity.
