The antioxidative effect of ganhuangenin (GHG), isolated from Scutellaria baicalensis Georgi, was examined by measuring its ability to suppress the formation of phospatidylcholine hydroperoxide (PCOOH). The results show that a pretreatment with GHG effectively suppressed PCOOH formation, which was
We previously showed that ganhuangenin (GHG) has beneficial antioxidative properties against lipid peroxidation in tissues of Sprague-Dawley (SD) rats. In this study, the effect of GHG on immunoglobulin E (IgE), histamine and leukotriene B(4) (LTB(4)) levels of cells isolated from SD rats was
Scutellariae radix, the root of Scutellaria baicalensis, has long been applied in traditional formulations and modern herbal medications. Propionibacterium acnes (P. acnes) in follicles can trigger inflammation and lead to the symptom of inflammatory acnes vulgaris. This study was aimed at
OBJECTIVE
To isolatate and elucidate the antioxidant constituents from acetone extract of Scutellaria rehderiana.
METHODS
Chemical constituents were isolated by several column chromatographies and their structures were elucidated on the basis of standard compounds and spectral analysis.
RESULTS
Five
The effect on the IgE content induced by concanavalin A in spleen lymphocytes of the presence wogonin, ganhuangenin, wogonoside and 3,5,7,2',6'-pentahydroxyl flavanone was investigated. These flavonoid components markedly inhibited the histamine released from cells stimulated with the calcium
