Plant based medicines are the base of many of the modern pharmaceuticals we used today. The aim of the study was to find out the active constituents of Petroleum ether, chloroform, benzene, acetone, methanol and aqueous leaf and seed extract of Eucalyptus citriodora and Lawsonia inermis. A qualitative phytochemical analysis was performed for the detection of alkaloids, flavonoids, steroids, carbohydrates, saponins, tannins and volatile oils. Flavonoids, carbohydrates and tannins present in petroleum ether, acetone extract of Lawsonia inermis leaf. Chloroform and acetone extract shows the presence of volatile oils whereas steroids were found only in acetone and methanol extract of L. inermis leaf. Alkaloids are totally absent in all leaf as well as seed extract of L. inermis. Tannins were found to be present in all extracts of Eucalyptus citridora. Flavonoids, steroids and volatile oils are present in almost all extracts of E. citridora leaf and seeds. https://www.biotech-asia.org/vol6no2/phytochemical-evaluation-of-eucalyptus-citriodora-hook-and-lawsonia-inermis-linn/ Lawsonia inermis; Eucalyptus citridora; Percent extractive value
