| Summary: | <i>Rosa</i> species are widely used in folk medicine in different countries of Asia and Europe, but not all species are studied in-depth. For instance, <i>Rosa beggeriana</i> Schrenk, a plant which grows in Central Asia, Iran, and some parts of China, is little described in articles. Column and thin-layer chromatography methods were used to isolate biologically active substances. From a study of fruits and leaves of <i>Rosa beggeriana</i> Schrenk, a large number of compounds were identified, seven of which were isolated: 3β,23-dihydroxyurs-12-ene (<b>1</b>), β-sitosterol (<b>2</b>), betulin (<b>3</b>), (+)-catechin (<b>4</b>), lupeol (<b>5</b>), ethyl linoleate (<b>6</b>), and ethyl linolenoate (<b>7</b>). Their structures were elucidated by <sup>1</sup>H, DEPT and <sup>13</sup>C NMR spectroscopy, mass spectrometry, and GC-MS (gas chromatography–mass spectrometry). The study also identified the structures of organic compounds, including volatile esters and acids. Consequently, comprehensive data were acquired concerning the chemical constitution of said botanical specimen.
