Abstract
The objective of the present study was to evaluate the phenolic content (TPC), flavonoids content (TFC), phenolics profile and the antiradical activity of Ocimum sanctum and Ocimum basilicum methanol extracts. Antiradical activity of extracts was determined by scavenging of DPPH center dot radicals. The individual phenolic acids and flavonoids were identified using HPLC. Phenolic acids (i.e. caffeic, sinapic, gallic, ferulic, and syringic acids) and flavonoids (i.e. quercetin, luteolin, rutin, apigenin and kaempferol) were identified and quantified in Ocimum sanctum and Ocimum basilicum. TPC of Ocimum sanctum and Ocimum basilicum were 386 mg and 383 mg gallic acid equivalent (GAE)/100g of extract, while TFC were 201 mg and 203 mg quercetin equivalent (QE)/100g of extract. Both extracts exhibited strong antiradical activity against DPPH center dot radicals.
