摘要
目的:分离鉴定红丝线(Peristropheroxburghian)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5,6dimethoxy2(3H)benzoxazolone,化合物I为2amino7,8dimethoxy3Hphenoxazine3one。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,I)。
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).
