    Journal: Zhongguo Zhong Yao Za Zhi; 2004 Sep; 29(9):863-4. PubMed ID: 15575204.
    Abstract:
    OBJECTIVE: To isolatate and elucidate the antioxidant constituents from acetone extract of Scutellaria rehderiana. METHOD: Chemical constituents were isolated by several column chromatographies and their structures were elucidated on the basis of standard compounds and spectral analysis. RESULT: Five compounds, oroxylin A, wogonin, baicalein, ganhuangenin, ganhuangemin were isolated from acetone extract of S. rehderiana. Baicalin was obtained from methanol extract of S. rehderiana. CONCLUSION: Ganhuangemin was isolated from the plant for the first time. Baicalein and ganhuangenin have stronger antioxidant activity than that of BHT (butylated hydroxytoluene).
