  • Objective To study the chemical constituents in Rubus corchorifolius. Methods Chromatography on silica gel column,Sephadex LH-20 columm,recrystallization and preparative HPLC technique were used to isolate and purify the compounds.Spectroscopy methods including UV, IR, EI-MS, ES-MS and NMR were used to elucidate the structures of compounds. Results Ten compounds were obtained and identified as: stigmasterol (1), beta-sitosterol (2), daucosterol (3), 4-hydro-3-methlbenzal acid (4), apigenin (5), luteolin (6), Homofukinolide (7), Bakkenolide-B (8), Bakkenolide-D (9), 3,5,9-trihydroxy-7,8-dihydrocyclopenta[g]chromene-2,6-dione(10). Conclusion Compound 4, 5, 6, 7, 8, 9 were isolated from Rubus corchorifolius for the first time. Compound 10 was a new compound.
