Abstract: Mulberry raw juice organic acids were detected by ion exclusion chromatography, with anion exchange column (Ion Pac AS11) and three kinds of mobile phase (18mmol/L NaOH, 24mmol/L NaOH, 2mmol/L Na2B4O7) respectively. The main organic acids in the mulberry raw juice includ malic acid, tartaric acid, oxalic acid, succinic acid, citric acid, acetic acid and formic acid, while two kinds of inorganic radicals (Cl-, SO42-) are identified.

Key words: mulberry, organic acids, ion exclusion chromatography, juice
