周氏克金岩方抗A549肺癌细胞多糖组分的研究

Study on Effective Polysaccharide of Anti-Human Lung Cancer A549 Cells in Zhou’s Prescription for Resolving Mass

目的研究周氏克金岩方治疗肺癌的物质基础。方法用醇沉法提取周氏克金岩方多糖,采用Sevag法纯化,DEAE纤维素阴离子交换树脂制备多糖组分,紫外光谱检测蛋白存留情况,红外光谱分析组方药的归属,采用蒽酮-硫酸比色法测定多糖组分含量。结果该有效多糖组分在240nm和260nm处无吸收,其红外光谱图与组方药玉竹、猫爪草和仙鹤草的红外光谱图有很大的相似性,周氏克金岩方中该多糖组分含量为1.41%。结论抗A549肺癌细胞多糖组分不含蛋白和核酸,来源于组方药玉竹、猫爪草和仙鹤草,周氏克金岩方中含有一定量的多糖组分。

Objective To study content and ascription of the composition of the polysaccharides from Zhou＇s Prescription for Resolving Mass. Method The polysaccharide was extracted by ethanol precipitation, and purified by savage method. DEAE-ceUulose anion exchange resin was used to prepare the composition of polysaccharides. UV-spectra was used to detect protein and IR-spectra was used to analyses the ascription of the composition of polysaccharides. The content of the composition of polysaccharides was determined by anthranone-sulfuric acid method. Result There was no absorption at 240 nm and 260 nm. The IR spectrum graph of the polysaccharides was similar to Polygonatum odoratum, Radix Ranunculi Temati and Agrimonia pilosa Ledeb. The content of the composition of polysaccharides was 1.41%. Conclusion The composition of polysaccharides does not contain proteins and nucleic acids, and come from Polygonatum odoratum, Radix Ranunculi Temati and grimonia pilosa Ledeb.
