Phytochemical Screening, Total Phenols and Total Flavonoids Content of Cynara cornigera roots

Abstract

The aim of the current study is to detected the phytochemical compounds in the methanolic extract of Cynara cornigera roots. In addition quantify the total phenol content (TPC), total flavonoid contents (TFC) using spectrophotometric methods. The total phenolic compounds determined by using Folin Ciocalteu. While, the total flavonoid contents of the extract determined using quercetin reference standard method. Phytochemical analyses of the extract was carried out using standard methods to assess the major classes of phytochemicals alkaloids, flavonoids, phenolic, tannins, saponins, steroids, terpenoids, carbohydrate and glycosides. Phytochemical screening revealed that all the tests were positive except alkaloids, saponins, and steroids. The total phenol and flavonoids content of the methanolic extract of Cynara cornigera roots show high concentration. The estimated phenolics and flavonoids content are 17.59 mg/g and 18.62 mg/g respectively. These findings suggest that the methanol extract of Cynara cornigera roots has potential invitro antioxidant activities. According to the obtained results, the roots of Cynara cornigera considered as a rich source of natural antioxidants since its methanolic extract contains many effective chemical compounds that demonstrate the highest free radical scavenging capacity
