For triterpene analysis, we used a mobile phase composed of toluene: chloroform:methanol (40:40:10 v/v) and sulfuric anisaldehyde/heat as a detection reagent. The plate was observed under visible light. For the monitoring of polyphenols and flavonoids, chloroform: acetone: formic acid (75:16.5...
The chemical formula of a compound is a symbolic representation of its chemical composition. Chemical formulae provide insight into the elements that constitute the molecules of a compound and also the ratio in which the atoms of these elements combine to form such molecules. For example, the ...
Such solvents as hexane, toluene, benzene, methylene chloride, chloroform, ethyl acetate, tetrahydrofuran, triethylamine, pyridine, or acetic anhydride are suitable for use with these catalysts. Among the tertiary alcohols which can be easily acylated with DMAP and PPY, mention should be made of l...
