Antioxidant Activity of Solvent Fractions of Taraxacum officinale (Dandelion) Leaves

摘要

Methanolic crude extract of dandelion (Taraxacum officinale^ leaves was fractionated in solvents and antioxidant activity evaluated. The ethyl acetate and butanol fractions showed high antioxidant activities in all the assays. Methylene chloride and water fractions demonstrated moderate activity, whereas the hexane fraction had relatively lower activity.
