ULTRASOUND-ASSISTED EXTRACTION AND CHARACTERIZATION OF POLYSACCHARIDE FROM MARYLAND TOBACCO LEAVES

Ultrasound-assisted extraction (UAE) of polysaccharide from Maryland tobacco leaves was studied by response surface methodology. Furthermore, the crude polysaccharide was purified and two components (Fr-I and Fr-II) were obtained. FT-IR spectral analysis of the purified polysaccharide revealed promi...
