Abstract: In this paper , the extracting and purifying technology of the folacin in fruits and vegetables was studied. We designedthe orthogonal test for the solvent, developing agent and sorbent. The results showed: extracted with hot boiling metaphosphoricacid , absorbed with active carbon, developed with the mixture solution of 3% ammonia and 70% anhudrous alcohol, the conclusiongained the ends of extraction and purifying comparative completeness. And we measured the content of folacin with thefluorescence spectrophotometer. The recovery ratio was beyond 95%, the relative deviation was below 2.5%. The results wassatisfied.

Key words: folacin, fluorescence analysis, extraction, purifying, sorbent
