目的探索壳聚糖絮凝澄清工艺与醇沉工艺对党参水提液中主要化学成分的影响。方法以党参炔苷含量、浸膏得率及HPLC指纹图谱各组分的相对表观含量作为评价指标,考察壳聚糖絮凝澄清工艺与醇沉工艺2种纯化工艺对党参水提液的影响。结果壳聚糖絮凝澄清工艺处理的党参水提液其浸膏得率明显高于醇沉工艺,且对极性较强组分的保留效果显著优于醇沉工艺;醇沉工艺对党参炔苷保留量稍高于壳聚糖絮凝澄清工艺,且对极性较弱组分的保留效果较好。结论上述2种工艺对党参水提液中主要化学成分的影响存在一定的规律,可为党参及其他中药水提液纯化工艺的合理选择提供参考。

Objective To explore the effects of chitosan flocculation clarification process and alcohol precipitation process on the principal chemical constituents of water extract of Codonopsis Radix. Methods The influence of two purification processes on water extract of Codonopsis Radix was investigated through lobetyolin contents, extract yield, and relative apparent content of each component in HPLC fingerprint as evaluation indexes. Results Chitosan flocculation clarification process showed a significantly higher extract yield of water extract compared with alcohol precipitation process, and it has...
