The paper deals with the isolation of constituents from light petrol and chloroform extracts of the leaves of Philadelphus coronarius L., Saxifragaceae. From the light petrol extract uvaol and 3 beta,28-dihydroxyoleanane-11(12),13(18)-diene were isolated, while coumarins (umbelliferone, scopolin), stigmasteryl-3 beta-D-glucoside and the alcane type carbohydrate-C29H60 were isolated from the chloroform extract. The isolated compounds were identified by spectroscopic means and by comparison with standards and the literature data.
