Abstract:

To modify the acidified acetone-sodium acetate extraction technique of hemin from porcine blood, ultrasonic was used to disrupt porcine red blood cells for accelerating the release of intracellular hemoglobin. Meanwhile, extracted hemin was structurally characterized by infrared spectroscopy and UV-Visible absorption spectroscopy, and quantitative analysis was carried out by UV-Visible absorption spectroscopy. Results showed that crucial parameters affecting ultrasonic disruption of porcine red blood cells such as ultrasonic power, water/ethanol volume ratio and ultrasonic treatment time were optimized to be 800 kW, 15:1 and 6 min, respectively. Under optimized parameters, 86.62% hemin with 92.67% purity was extracted. This method demonstrates the merits of simplicity, low cost and high purity of final products.

Key words: ultrasonic, acidified acetone method, hemin, extraction, orthogonal array design
