Six alkaloids were isolated from Gynura segetum (Lour.) Merr. Four of them were identified. Alkaloids I and II were identified as known senecionine and seneciphylline, respectively. Alkaloids III and IV were found to be new compounds named seneciphyllinine and (E)-seneciphylline respectively. Their structures were confirmed on the basis of spectral data (UV, IR, MS, 1HNMR, 13CNMR, C-H COSY).
从一点红中分离出六种生物碱。其中四种已被鉴定出来。生物碱I和II分别被鉴定为已知的千里光碱和千里光菲灵碱。生物碱III和IV被发现是新化合物，分别命名为千里光菲宁碱和（E）-千里光菲灵碱。它们的结构通过光谱数据（紫外光谱、红外光谱、质谱、1H核磁共振、13C核磁共振、碳氢化学位移相关谱）得以确证。
