separate and identify the water-soluble chemical constituent from Radix Isatidis. Method: The Radix Isatidis water extract underwent adsorption by HP-20 macroporous resin
the portion eluted by ethanol of different content was isolated and purified on silica gel column repeatedly. The structures of the compounds were identified by spectra data. Result: 6 compounds temporarily separated from Radix Isatidis water extract
were identified as: (+)-isolariciresinol(1)
lariciresinol-4-bis-O-β-D-glucopyranoside(2 )
lariciresinol-4
4'-bis-O-β-D-glucopyranoside(3 )
epigoitrin(4 )
indole-3-acetonitrile-6-O-β-D-glucopyranoside(5 )
4-hydroxyindole-3-carboxaldehyde(6 ). Conclusion : For the first time
