Title: Studies on Chemical Constituents of Potentilla chinesis
Abstract: OBJECTIVE To study the chemical constituents of Potentilla chinesis. METHODS Chemical constituents were isolated by Toyopearl HW-44,Sephadex LH-20,preparative HPLC,and silica gel column chromatographies. The structures were elucidated on the basis of spectral data analysis. RESULTS Ten compounds ,quercetin-3-O-α-L-arabinofuranoside (Ⅰ) ,quercetin-3-O-α-L-rhamnoside (Ⅱ),kaempferol-3-O-α-L-arabinofuranoside (Ⅲ) , kaempferol-3-O-β-D-(6-O-cis-p- coumaroyl) glucopyranoside (Ⅳ),kaempferol-3-O-β-D-(6-O-trans-p-coumaroyl) glucopyranoside (Ⅴ),4′,5,7-tri- methoxy-flavonol (Ⅵ),blumenol A (Ⅶ),dihydrosyringenin (Ⅷ),β-sitosterol (Ⅸ),daucosterol (Ⅹ) were isolated from P. chinesis. CONCLUSION Compound Ⅰ-Ⅷ were isolated from the plant for the first time,compound Ⅴ-Ⅷ were isolated from the genus Potentilla for the first time.
