Seventeen quinolizidine alkaloids, including a new matrine-type one, sophcence A, were isolated from the roots of Sophora flavescens Alt. The structure of compound was elucidated by means of 1D and 2D NMR, as well as HR-ESI-MS spectroscopic data. The NMR data of (-)-Δ7-dehydrosophoramine () and oxy-N-methylcytisine () were reported for the first time. In addition, (+)-sophoranol () exhibited moderate inhibition on lipopolysaccharide (LPS)-induced nitric oxide (NO) production in RAW 264.7 macrophages with IC50 value of 22.14 μM, while lupanine () was found to inhibit the growth of human glioma stem cells GSC-3# at 20 μg/mL.
