Summary:The present invention relates to the technology field of extracting chlorophyll. High purity pheohorbide A is extracted by using red alga, blue green alga and yellow green alga as raw material and through the processes of edible color extraction with low density solution of acid, alkali, salt and alcohol; extraction to refine chla, liquid phase process to prepare pheophorbide A and eliminating acid with adsorbent. Owing to that no chlorophyll B and C is contained in the raw material, the present invention can obtain high purity pheophorbide A and has economic utility greatly higher than that of conventional process.
