• Scutellaria indica
• Labiatae
• Flavonoid
• Anti-inflammatory activity
• RAW 264.7 cells

Six new phenolics, scutellariosides A-F (1-3, 5-6, and 8), together with six known compounds (4, 7, 912) were isolated from the whole plant of Scutellaria indica (Labiatae). The chemical structures of these compounds were determined by spectroscopic analyses including 2D NMR. Their anti-inflammatory activities were evaluated against LPS-induced NO production in macrophage RAW 264.7 cells. Among them, compounds 10-12 had inhibitory effects with IC50 values ranging from 7.2 to 27.8 mu M. Compound 12 reduced LPS-induced iNOS expression in a dose-dependent manner.
