摘要:

为了优选菝葜多糖的分离纯化工艺,以多糖纯度、多糖出膏率与吸附率等为指标,考察醇沉静置温度、醇沉静置时间与大孔吸附树脂型号等因素,确定菝葜多糖的最佳醇沉工艺与大孔吸附树脂纯化工艺。得到菝葜多糖最佳醇沉工艺为取含生药1.0 g/mL的药液,加入乙醇,使乙醇体积分数达到80%,醇沉1次,室温25 ℃静置12 h,抽滤得醇沉物,70 ℃干燥;纯化工艺为采用AB-8型大孔吸附树脂,用1 BV的2.0 mg/mL(以粗多糖计)的上样液,以2 BV/h的流速上样,再用3 BV的纯水以3 BV/h的流速进行洗脱。结果表明该优选工艺稳定可靠,可用于菝葜多糖的分离纯化。

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.
