Four new flavanones (I-IV) and a new flavone (V) were isolated from the root of Scutellaria indica L., together with 2(S)-5,2'-dihydroxy-7,8,6'-trimethoxyflavanone, 5,7-dihydroxy-8,2'-dimethoxy flavone, rivularin, 5,2',6'-trihydroxy-7,8-dimethoxyflavone, scutevurin, 5,7,4'-trihydroxy-8-methoxyflavone, wogonin, alpinetin, caldamomin and wogonin 7-O-glucuronide.Compounds I-V (Fig. 1) were identified based on spectral data and simple chemical modifications.Keywords--Scutellaria indica; Labiatae; flavonoid; flavone; flavanone; chalcone; structure elucidation

An h.p.l.c. system that separates carbohydrates as their methyl glycosides has been used to study the products obtained on treatment of various carbohydrates with methanolic hydrogen chloride.Results are presented for the monosaccharide composition of several polysaccharides, lactone and ester formation during the treatment of D-glucuronic acid, and relative rates of glycosidation vs. esterification during the treatment of D-galacturonic acid.
