【Abstract】 Object To investigate the chemical constituents from the methanol extract of the root of Rubus irenaeus Focke. Methods EtOAc extraction, normal and reverse phase silica gel column chromatography were used for isolation. Spectroscopic methods ( 13 CNMR , 1HNMR , DEPT, 2DNMR, and FAB-MS) and comparison with authentic samples were used for identification. Results Ten compounds were isoated and characterized as 2α, 19α-dihydroxyl-3-oxo-urs-12-en-28-oic acid (Ⅰ), 2-oxo-pomolic acid (Ⅱ), fupenzic acid (Ⅲ), euscaphic acid (Ⅳ), 2α, 3α, 19α-trihydroxyl-olean-12-en-28-oic acid (Ⅴ), 2, 3-O-isopropylidenyl euscaphic acid (Ⅵ), pomolic acid (Ⅶ), 2α, 3β-dihydroxyl-lup-20(29)-en-28-oic acid(Ⅷ), catechin (Ⅸ) and daucosterol (Ⅹ). Conclusion These compounds were obtained from this plant for the first time.更多还原
