硅胶G-硅藻土G(1:1重量)铺15mg/cm~2薄板,105℃活化后,以二氯甲烷:醋酸乙酯:苯:乙醇(30:40:20:10)混合溶剂(用前加1.5％浓氨水)为展开剂。点一定量样品数处,展层后取其中一处用1％硫酸铈和2.5％钼酸的10％硫酸溶液为显色剂显色,确定分离后斑点位置。将未现色的相应斑点刮下,无水
Silica gel G-Celite G (1: 1 by weight) was coated on a 15 mg / cm 2 thin plate and activated at 105 ° C. with a mixed solvent of methylene chloride: ethyl acetate: benzene: ethanol (30:40:20:10) Before using 1.5% concentrated ammonia) as the developing agent. A certain amount of sample points at the exhibition, after taking one of the layers with 1% cerium sulfate and 2.5% molybdic acid solution of 10% sulfuric acid as a reagent color to determine the location of spots after separation. Scratch the non-colored corresponding spots without water
