Abstract
Rosa species are widely used in folk medicine in different countries of Asia and Europe, but not all species are studied in-depth. For instance, Rosa beggeriana 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 Rosa beggeriana Schrenk, a large number of compounds were identified, seven of which were isolated: 3β,23-dihydroxyurs-12-ene (1), β-sitosterol (2), betulin (3), (+)-catechin (4), lupeol (5), ethyl linoleate (6), and ethyl linolenoate (7). Their structures were elucidated by 1H, DEPT and 13C 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.
