The methanol extracts of the seeds had significantly higher (P<0.05) superoxide radical scavenging activity with the concentration for 50% inhibition (IC50) value of 98.73μg/mL for O. basilicum, 121.57μg/mL for A. graveolens and 166.16μg/mL for L. sativum. The results indicated that all the seed extracts showed excellent H2O2 scavenging activities. IC50 values for H2O2 scavenging activity by methanol extract of O. basilicum, A. graveolens, L. sativum and butylated hydroxyanisole were found to be as 49.9, 52.3, 65.2 and 49.6μg/mL, respectively. O. basilicum methanol extract had significantly (P<0.05) higher 1,1-diphenyl-2-picryl-hydrazyl scavenging effect than the other two seeds. The methanol extracts of three seeds were better in Fe+2 chelating activity, reducing power and higher in the content of total phenol as compared with ethanol and water extracts. +PRACTICAL APPLICATIONS: Recent epidemiological studies have strongly suggested that consumption of certain plant materials such as seeds, leaves, fruits and roots may reduce the risk of chronic diseases related to oxidative stress on account of their antioxidant activity and promote general health benefits. In this study, all seeds extracts exhibited good antioxidant activity (78.3-96.9%) at concentration 500μg/mL. Total phenolic content in the seed extracts ranged from 51 to 92mg GAE/100g extract. In addition, there was a statistically significant correlation between the amount of phenolic compounds and antioxidant activity (R2=0.9058, P<0.05) in all the seed extracts. Therefore, O. basilicum, A. greveolens and L. sativum seed extracts have the potential to be developed into dietary supplements and nutraceuticals. © 2010 Wiley Periodicals, Inc.EnglishAll Open Access; Gold Open AccessApium graveolensApium graveolens var. dulceLepidium sativumOcimumOcimum basilicumEthanolHealth risksMethanolOxygenPhenolsPlants (botany)SeedWater contentAntioxidant activitiesAntioxidative propertyApium graveolensChelating activityChronic diseaseDietary supplementsEpidemiological studiesHealth benefitsLepidium sativumMethanol extractNutraceuticalsOcimum basilicumPhenolic compoundsPhenolic contentPlant materialReducing powerScavenging activitiesScavenging effectSeeds extractsSuperoxide radicalTotal phenolic contentTotal phenolsWater extractsSolvent extractionArticle10.1111/j.1745-4514.2010.00366.x
