Objective:To study the chemical constituents from the leaves of Rubus alceaefolius Poir. Methods: Chemical constituents were isolated and identified by the repeated chromatographies and spectral analyses. Results: Six compounds were obtained as alcesefoliside(1), hyperoside(2), vomifoliol(3), β sitosterol(4), daucosterol(5), and dotriacontyl alcohol(6). Conclusion: Compound 1 was a new compound. The other compounds were obtained from this plant for the first time.
