Extraction of baicalin and characterization of its methylated derivatives. X-ray structure of 7-hydroxy-5,6-dimethoxyflavone 7-glucuronide methyl ester dihydrate
Baicalin has been isolated and four of its methyl derivatives have been characterised by IR, UV, mass, 1H and 13C NMR and one of these, 7-hydroxy-5,6-dimethoxyflavone 7-glucuronide methyl ester, was subjected to an X-ray crystallographic analysis.
