红丝线中两个新化合物的结构鉴定

STRUCTURE ELUCIDATION OF TWO COMPOUNDS FROM PERISTROPHE ROXBURGHIANA

    摘要
  • 摘要: 目的：分离鉴定红丝线(Peristrophe roxburghian)地上部分的化学成分。方法：红丝线的地上部分经60%乙醇提取，硅胶和氧化铝柱色谱分离，经化学和UV，IR，NMR及MS光谱解析确定结构。结果：分得两个化合物，经鉴定化合物I为5,6-dimethoxy-2(3H)-benzoxazolone，化合物II为2-amino-7,8-dimethoxy-3H-phenoxazine-3-one。结论：两个化合物均为新化合物，分别命名为红丝线酰胺(peristrophamide, I)和红丝线素peristrophine, II)。

     

    Abstract: AIM: To study the chemical constituents of Peristrophe roxburghiana. METHODS: The aerial parts of Peristrophe roxburghiana were extracted with EtOH and isolated by LC, the structures were determined by UV, IR, NMR and MS. RESULTS: Two compounds were identified as 5,6-dimethoxy-2(3H)-benzoxazolone(I) and 2-amino-7,8-dimethoxy-3H-phenoxazine-3-one(II) respectively. CONCLUSION: Two chemical constituents obtained were new compounds and named peristrophamide(I) and peristrophine(II).
