Isolation and structure elucidation of 5'-O-beta-D-glucopyranosyl-dihydroascorbigen from Cardamine diphylla rhizome.
From the methanol extract of Cardamine diphylla rhizome, 5'-O-beta-d-glucopyranosyl-dihydroascorbigen (1) and 6-hydroxyindole-3-carboxylic acid 6-O-beta-d-glucopyranoside (2) were isolated. The structures of the compounds were elucidated using spectroscopic methods. This is the second report on the presence of a glucosylated indole ascorbigen in plants.
