Study on Chemical Constituents of Scutellaria indica L.

Objective To study on chemical constituents of genus of Labiatae Scutellaria Han grass Scutellaria indica L. Methods Chromatographic methods were used to isolate compounds fromScutellaria indica L,and spectroscopic methods were used to identify the structures. Results Five compounds were isolated and their structures were elucidated. Respectively Apigenin( 1),Luteolin( 2),Apigenin-7-O- β-D- pyran glucuronide( 3) 、Luteolin-7-O-β-D-pyran glucuronide( 4) and hemipholin( 5). Conclusion Compounds 3~ 5 were isolated from this plant for the first time.
