Studies on the Constituents of Sophora flavescens AITON

New 2-alkylchromone derivatives were isolated from the epigeal part of Sophora flavescens AITON. These compounds were obtained as a mixture of 2-n-heneicosyl-5, 7-dihydroxy-6, 8-dimethylchromone, 2-n-tricosyl-5, 7-dihydroxy-6, 8-dimethoxychromone and the homologous compounds, in which 2-alkyl groups...

Summary:New 2-alkylchromone derivatives were isolated from the epigeal part of Sophora flavescens AITON. These compounds were obtained as a mixture of 2-n-heneicosyl-5, 7-dihydroxy-6, 8-dimethylchromone, 2-n-tricosyl-5, 7-dihydroxy-6, 8-dimethoxychromone and the homologous compounds, in which 2-alkyl groups are n-undecyl, n-tridecyl, n-pentadecyl, n-heptadecyl and n-tricosyl. Their structures were clarified by the spectral and chemical data, and the synthesis of 2-n-heptadecyl-5, 7-dihydroxy-6, 8-dimethylchromone.
