Objective:
To study the chemical constituents in the root of Isatis indigotica.
Method:
The constituents root were separated through various chromatographic techniques and their structures were elucidated by means of physicochemical properties and the analysis of their spectral data.
Result:
Eleven compounds were isolated and identified as (+) -isolariciresinol (1), lariciresinol (2), lariciresinol-9-O-beta-D-glucopyranoside (3), lariciresinol-4'-O-beta-D-glucopyranoside (4), lariciresinol-4,4'-bis-O-beta-D-glucopyranoside (5), 3-formylindole (6), 1-methoxy-3-indolecarbaldehyde (7), 1-methoxy-3-indoleacetonitrile (8), deoxyvasicinone (9), epigoitrin (10), adenosine (11).
Conclusion:
Compounds 4-8 were isolated from I. indigotica for the first time.
