Abstract

From the leaves of Scutellaria strigillosa, 14 compounds, chrysin, apigenin, 5,7,2′-trihydroxyflavone, norwogonin, ursolic acid, 6β-hydroxy-4-stigmasten-3-one, 6β-hydroxy-4,22-stigmastadien-3-one, 2 R,4′ R,8′ R-γ-tocopherol, (S)-5,5′ -bi-γ-tocopheryl, (R)-5,5′ -bi-γ-tocopheryl, solanachromene, tocopherylquinone, jodrellin T, and 14,15-dihydrojodrellin T were isolated. The structures were determined on the basis of chemical and spectral data.
