Methods The chemical constituents were isolated and purified by column chromatography on silica gel column. NMR spectra were used for structural identification. Results Thirteen compounds were isolated and identified as quercetin (1), (2S,3S,4R, lOLg-2-[(2"R)-2'-hydroxytetracosanoyl amino]-10-octadecene-l,3,4- triol (2), aralia cerebroside (3), 5,5'-dibuthoxy-2,2'-bifuran (4), ^-sitosteryl- 3^-glucopyranoside-6'-O-palmitate (5), B-sitosterol palmitate (6), myricadiol (7), protocatechuic acid (8), p-hydroxybenzoic acidethyl ester (9), isovanillin (10), trans- cinnamicacid (I 1), palmiticacid (12), and stearicacid (13). Conclusion Compounds 2-13 are isolated from this plant for the first time.展开更多
