The plant Erythroxylum monogynum, belonging to the family Erythroxylaceae, is a shrub cultivated almost in all districts of south west India. In the present work, physiochemical standards and phytochemical constituents of leaf of Erythroxylum monogynum were studied and reported that it contains alkaloids, carbohydrates, flavonoids and glycosides. Further, alcoholic extract of leaf of Erythroxylum monogynum is screened for antimicrobial activity against the organism Escherichia coli, Pseudomonas aeruginosa and Staphylococus aureus keeping the antibiotic amikacin as a positive control and the result showing that 12 mm and 13 mm zone of inhibition was observed in 45 and 60 mcg/mL of alcoholic extract of leaf, respectively where as 12 mm zone of inhibition was observed in 30 mcg/mL of amikacin in Escherichia coli.
