Determination of Antioxidant Capacity and HPLC Analysis of Gallic Acid Plus Rutin in Some Lamiaceae Plants Growing in the East of Libya

Lamiaceae family comprise a wide range of medicinal and aromatic plant species with strong antioxidant properties multiple pharmaceutical applications in folk medicine. Mentha piperita L., Ocimum basilicum, Origanum vulgare L, Rosmarinus officinalis Salvia L. Thymus capitatus, are edible plants Libya, belonging to this family. The current work aims evaluate gallic acid rutin contents the methanolic extract mentioned using RP- High performance liquid chromatography (HPLC) assess their by applying DPPH radical scavenging assay. content were found be considerable all studied, most remarkably capitatus area under peak (56.14% 54.62% respectively), while lower detected basilicum (34.44%), (28.98%), Mentha L.(26.09%), and Salvia (24.34%). On other hand, it was noted that is less quantities compared previous results. extracts Organium vulgare and Thymus capitatus had significant potential standard vitamin C 0.34 ± 0.03 0.46 0.02 mg/mL respectively, capacity recoded for (0.59 0.01), (0.60 L (0.65 0.07), basilicum (0.99 0.02). In conclusion, reported results point out significance as source agents high promising capability affect redox state.
