Four endangered plant species Mimusops elengi, Erythroxylum monogynum, Holoptelea integrifolia and Catha edulis were selected to estimate phytoconstituents and quantify total phenols, tannins and flavonoids. Healthy leaves were collected from Mahatma Gandhi Botanical garden and Herbarium, GKVK, University of Agricultural Sciences, Bengaluru and after drying the leaves were subjected for extraction using methanol as solvent and dissolved in 100ml of methanol and stored in air tight bottles for further phytochemical analysis. Total content of phenols, tannins with Gallic acid curve and flavonoids with quercetin by standard methods were estimated. The leaf extract of Mimusops elengi contained maximum amount of tannins and Erythroxylum monogynum contained minimum amount. Maximum amount of phenols was found in Holoptelea integrifolia. Maximum flavonoids was recorded in Catha edulis. It is further suggested that leaves of Mimusops elengi, Erythroxylum monogynum, Holoptelea integrifolia and Catha edulis prove to potential plants for bioprospection evaluation due high content of phenols, tannins and flavonoids. Simultaneously the conservation of these species must be indicated in our localities, since these are highly important plants and are being exploited due to which these have gained endangered status.
