Abstract:

The purpose of this study is to optimize the polysaccharide purification technique from Smilacis Chinae Rhizoma. With the purity, paste rate, adsorption rate, and other parameters as indicators, the optimal alcohol precipitation process and macroporous resin purification technique were determined by investigating the alcohol precipitation temperature, alcohol precipitation time, macroporous resin type, and other factors. The optimum alcohol precipitation process is as follows. Take 1.0 g/mL solution and add ethanol to make the alcohol content reach 80%. Then, perform alcohol precipitation once and leave it at 25 ℃ for 12 h. Finally, pass it through a suction filter to obtain alcohol precipitate and dry it at 70 ℃. Optimum purification technique is as follows. Load 1 BV sample (2.0 mg/mL) and pass it through AB-8 resin at the rate of 2 BV/h, followed by elution through 3 BV pure water at the rate of 3 BV/h. The results show that the optimized process is stable and reliable and can be used for purifying.
