峨眉千里光Senecio fuberi Hemsl全草,已报道含有全缘千里光碱squalidine(Ⅰ)、阔叶千里光碱platyphylline(Ⅱ)和新阔叶千里光碱neoptatyphylline(Ⅲ)。采用一定pH梯度溶剂萃取,对Ⅰ,Ⅱ分离效果较好,水平行星式逆流层析可使Ⅰ,Ⅱ完全分离。Ⅱ,Ⅲ
The whole plant of Senecio fuberi Hemsl has been reported to contain squalidine (I), platyphylline (II) and neoptatyphylline (III). Solvent extraction with a certain pH gradient has better separation effect on I and II. Horizontal planetary countercurrent chromatography can completely separate I and II. II, III
