Abstract:

The purification of total flavonoids extracted from the shells of wild apricot using D101 macroreticular resin
was optimized using combination of single factor and orthogonal array experiments. The results showed that the optimum
purification conditions were determined as follows: sample concentration, 0.3 mg/mL; pH 2; flow rate for elution,
2 mL/min. With these parameters, the purity of total flavonoids was 51.63%. Therefore, D101 macroreticular resin was
effective in purifying total flavonoids from the shells of wild apricot with good stability and repetition.

Key words: shells of wild apricot, total flavonoids, macroreticular resin, purification
