| Abstrakt: | Objective: To investigate the chemical constituents of Rubus alceaefolius. Methods: Nine compounds were isolated and purified from the petroleum ether extract of 95% alcohol extract of Rubus alceaefolius by repeated column chromatography on silica, Sephadex LH-20 and structurally identified by spectral analysis. Results: The compounds were identified as chrysophanol(1), physcion (2), β-sitosterol(3), 3-oxotirucalla-7, 24-dien-21-oic acid(4), myricadiol(5), 19-α-hydroxy-3-acetyl-ursolic acid(6), N-benzoylphenylalaninyl-N-benzoylphenylalaninate(7), aurantiamide acetate(8) and euscaphic acid(9). Conclusion: Compounds land 4~8 are isolated from this plant for the first time, and compounds 4 - 8 are found in plants of Rubus genus for the first time. |
