The objective of present study was to determine the antioxidant activity of clove oleoresin and steam distilled clove extract. Higher level of phenolic content was found in steam distilled clove extract (256.50±0.45 mg of GAE/g) as compared to its oleoresin (177.03±0.35 mg of GAE/g). Antioxidant potential evaluated by β-carotene–linoleic acid model system of steam distilled and clove oleoresin were found to be 85.51±0.19% and 77.88±0.15%, respectively at a level of 200ppm. The radical-scavenging activity of steam distilled extract and oleoresin of clove were 88.93±0.23% and 80.84±0.36%, respectively at the same level of 200ppm by using DPPH method. Eugenol content in steam distilled extract of clove (0.518±0.005mg/ml) was significantly higher than that of clove oleoresin (0.433±0.007mg/ml). Eugenol content recovery was also affected by period of refluxing, clove extract refluxed for 4 hr found to be highest recovery in the steam distilled clove extract (0.763±0.007) than its clove oleoresin (0.635±0.020) with 13.904 min retention time by using RP-HPLC. The steam distilled clove extract was found to be highest antioxidant activity than its oleoresin counterparts.
