Studies on secondary metabolites, total phenol and flavonoid contents of Eupatorium cannabinum L. in Assam, India

Abstract

Eupatorium cannabinum L., an ethnobotanical plant of Deories of Assam, India, was screened for secondary metabolites such as alkaloids, terpenoids, phenols, flavonoids, tannins and saponins, and total phenol and flavonoid contents were also studied. It was found that the methanol extract of leaves contains all the screened compounds. The total phenol and flavonoid contents were found 64.82 mg/g and 25.05 mg/g in terms of gallic acid and quercetin equivalent respectively. Findings of the study provided evidence that crude extract of the plant species contains medicinally important bioactive compounds and justifies the uses of the plant in the traditional medicine for the treatment of different diseases.
