A method for the simultaneous determination of captan and folpet pesticide residues in apples was developed by solid-phase extraction and high performance liquid chromatography.

采用附剂和胶作附剂,建立了固萃取-高效液色谱法同时测定苹果中残留克菌和灭菌析方法。

A study was made of the effect of using silica gel and macroporous resin I as absorbent in column chromatography on the separation of tigogenin.

研究用胶、大孔树脂Ⅰ作为附剂柱色谱离效果。

Tigogenin was separated completely from the crude sapogenins by macroporous resin column chromatography,only simple solvent Ilelute was used in the column of the separate process.

用大孔树脂为附剂色谱方法在离过程中仅需要简单溶剂-Ⅱ,离出单一组剑麻皂甙元占粗皂甙元比率高达70%以上。
