Abstract: The present research work was undertaken with this aim to inspect the two medicinally important plants henna (Lawsonia inermis) of the family lythraceae and amla (Emblica officinalis) of family phyllanthaceae for their phytochemical analysis using ethanol and methanol reagents. The determinations under ethanol and methanol dilution of L. inermis for qualitative screening of tannins were positive, phlobatannins were positive, saponins were positive and in flavonids test results were also found positive. While the determinations under ethanol and methanol dilution of E. officinalis for qualitative screening of tannins test gave positive results, its phlobatannins gave positive results but less; saponins also gave positive results and flavonoids gave negative results. And then the determinations under ethanol and methanol dilution of L. inermis for quantitative screening of total carbohydrates were 6.547 and 6.276 µg/ml, reducing sugars 0.035 and 0.259 µg/ml, total proteins 0.245 and 0.420 µg/ml, phenolic compounds were 27.1191 and 35.2316 µg/ml, total flavonoids contents 0.154 and 0.261 µg/ml, tannins contents 0.664 and 1.292 µg/ml, and antioxidant activity were 2.411 and 3.218 µg/ml respectively.

Keywords: henna; amla; qualitative; quantitative; medicinal plants.
