A convenient laboratory method for partial purification of chlorophylls using dioxane is described. Chlorophyll in crude extracts with 90%-methanol or 80%-acetone was mixed with dioxane and then precipitated by drop-wise addition of water. Chlorophyll is precipitated in spherocrystalline form, leaving the bulk of carotenoids in solution. This is an efficient method for preparing chlorophyll from various plant materials, including higher plants and algae as well as photosynthetic bacteria (bac to riot hlo ro phyll).
