Abstract:
Objective To study the high polar constituents of Gastrodia elata.Methods The constituents were isolated by macroporous resin column chromatography combined with preparative HPLC and identified by spectral analyses and physico-chemical properties comparisons.Results Ten compounds were isolated from H2O and 20% EtOH fractions eluted from resin column and their structures were identified as citric acid monoethyl ester(Ⅰ),uridine(Ⅱ),adenine(Ⅲ),dactylose A(Ⅳ),uracil(Ⅴ),tyrosine(Ⅵ),N2-(p-hydroxybenzyl) guanosine(Ⅶ),1-isoferuloyl-?-D-glucopyranoside(Ⅷ),4-(?-D-glucopyranosyloxy) benzaldehyde(Ⅸ),and p-hydroxyl benzoic acid(Ⅹ).Conclusion Compound Ⅶ is a new compound named gastronucleoside.Other nine compounds are isolated from G.elata for the first time.
