Isolation and Identification of Hydrophilic Chemical Constituents from the Rattan of Akebia quinata Decne.
Seven compounds were isolated and purified by macroporous adsorptive resin HP-20, MCI gel, silica gel and Li Choprep RP-18 column chromatographies from the rattan of Akebia quinata Decne..Their structures were identified by spectroscopic methods as L-threo-guaiacylglycerol 8-O-β-D-glucopyranoside (1), guaiacylglycerol 9-O-β-D-glucopyranoside (2), 3-methoxy-4-hydroxyphenol l-O-β-D-glucopyranoside (3), 2-methoxy-4-hydroxyphenol 1-O-β-D-glucopyranoside (4), 2,6-dimethoxy-4-hydroxyphenol 1-O-β-D-glucopyranoside (5), di-O-methylcrenatin (6) and coniferin (7).Compounds 2-7 were isolated from the plant for the first time.
