GLYCOSYLATION OF PHENOLIC COMPOUNDS BY ROOT CULTURE OF PANAX GINSENG

Article abstract of DOI:10.1016/0031-9422(89)80269-9

A root culture of Panax ginseng was able to convert 3,5-dimethoxyphenol (taxicatigenin) into its glucoside (taxicatin), primeveroside and gentiobioside, methyl salicylate into its glucoside and gentiobioside, p-hydroxyacetophenone into its glucoside (picein), and coniferyl alcohol into dihydroconiferin <3-(3-methoxy-4-O-β-D-glucopyranosylphenyl>propan-1-ol>.The conversion ratio and the excretion ratio of the conversion products from methyl salicylate were higher than those from the more polar p-hydroxyacetophenone, 3,5-dimethoxyphenol and coniferyl alcohol.Among the conversion products, in particular, the excretion ratio (ER) of a glucoside into the medium decreased in proportion to the quotient of substrate's M_r divided by its RR_t on reversed phase HPLC (-ER<*>M_r/RR_t).Key Word Index - Panax ginseng; Araliaceae; ginseng; root culture; biotransformation; glycosylation; glucoside; primeveroside; gentiobioside; 3,5-dimethoxyphenol; methyl salicylate; p-hydroxyacetophenone.
