الملخص EN

This research included the study of the effect of aqueous plant extracted form two types of seaweed (Algex, Algamix), licorice plant and cultured barley seeds with three concentrations (0, 5, 10 gm/L) and two ways of methods addendum (spraying and irrigation) in mineral composition of the Senna plant Cassia acutifolia which had been planted in one of fenced wire house of the Department of biology /College of Education/ University of Mosul, at summer season (2011).

The analysis of the data were obtained by using the Complete randomized design (C.R.D) with four replications.

Separation and diagnosis of some chemical compounds from the plants under study had been done.

The results are as follows: Treatment with all extracts significantly affected most of the physiological traits under study compared with the control.

The Algamix extract sprayed at rate of (10gm/L) showed the highest potassium concentration in the leaves, while Algex extract gave the best concentration of magnesium in the leaves when used at (10gm/L), rather than sodium at (5 gm/L).

Spraying with Licorice extract showed a significant increase in calcium and phosphorus when used at (10 gm/L).

Glycoside and Aglycon compounds were separated and identification.

Diagnosis of both compounds were done by using infrared(IR) rays ,while another active compounds Sennoseid (A and B) were separated.

Their diagnosis was carrid out by using the high performance chromatography (HPLC) technique
