Identification of phenolic compounds in the buds of Algerian desf. Subsp. by antioxidant activity guided fractionation.

Objectives: A bio-guided selection and identification of the most active compounds obtained from Algerian desf. Subsp.

Methods: An antioxidant activity guided fractionation was performed on buds' extract using extensive chromatographic and spectroscopic techniques.

Separation and identification of bioactive compounds in Anabasis articulata (Forsk) Moq. roots.

In the present paper, for the first time, we are interested to separate and identify some bioactive fractions isolated from the roots of a Saharan plant Anabasis articulata, which is widely used in traditional medicine against cancer. The crude methanolic extract of the roots was fractionated on column chromatography, and eluted with dichloromethane/methanol each time with increasing polarity of methanol; 17 fractions were separated. One of these fractions named F12 showed more antioxidant activity to scavenge DPPH free radical with percentage inhibition of 95.
