In this study, the total phenolic, flavonoids and condensed tannin content of five commercial extracts (Thymus vulgaris, Ocimum basilicum, Rosmarinus officinalis, Lavandula angustifolia and Trigonella foenum-graecum) were examined.  For the determination of the total phenolic contents, the Folin-Ciocalteau procedure was used. The content of total flavonoid present in the extracts was measured using aluminum chloride assay.  Condensed tannins were determined according to the vanillin/HCl method. The results demonstrated that L. angustifolia extract possessed higher total phenol than the others followed by T. foenum-graecum extract. The T. foenum-graecum extracts showed the maximum content of flavonoids and tannins. From the results of the present study, it is concluded that these extracts are the best sources of phytomedicine.
