A comparison of flavonoid and phenolic content of different parts of Eryngium planum

Chochagh is a local name for Eryngium planum which can grow widely in Gilan province. The plant contains limonene, alpha pinnen,and folic acid. Besides, tannins and sucrose are also present in its roots. Traditionally, it is used to balance the appetite, as antibacterial/antifungal, to ease pains from arthritis and reduce inflammation, to increase breast milk and as a natural diuretic. It is also used as a traditional food flavoring. Here, we investigate and compare the antioxidant activity in different parts of the plant. Ethanol extracts from various parts of the plant were first prepared. Aluminum chloride colorimetry and Folin–Ciocalteu reagentswere used to measure the total flavonoid and phenol contents, respectively. In brief, after adding the reagents to each extract, the absorption was measured at 514 and 720 nm, respectively. It was found that all parts of the plant contained flavonoids and phenols.However, the flavonoid and phenol content of leaves was significantly higher than all other parts. The traditional medicinal plant, chochagh, possesses a considerable antioxidant activity in the form of flavonoids and phenols. It can, therefore, be considered as a possible candidate for use in pharmaceutical applications
