摘　　要：采用离子交联法,以高纯竹叶碳苷黄酮制剂(碳苷总质量分数>90%,记为H-BLF)和芫根阴离子多糖(TP)为原料,通过ε-聚赖氨酸(ε-PL)的阳离子桥键合制备了竹叶碳苷黄酮纳米混悬液(H-BLFnd),然后在混悬液中添加质量分数8%的γ-环糊精,经真空冷冻干燥得到纳米冻干粉(H-BLFnp),采用粒径分析、TEM、UV、FTIR、TG和DSC对其外观、性能、结构进行了表征。结果表明,H-BLFnp外观为白色粉状,表面光洁平整,色泽均匀,平均粒径为(679±10.2)nm,分散系数为0.349±0.004,包埋率为92.39%±0.34%。The nanodrops(H-BLFnd) were prepared by ionic cross-linking method, taking high purity C-glycoside flavonoids of bamboo leaf(H-BLF, the mass fraction of C-glycoside flavonoids was above 90%) and turnip polysaccharide(TP) as raw materials,ε-polylysine as a cross-linking agent. Subsequently, adding 8% mass fraction of γ-cyclodextrin into H-BLFnd suspension as protective agent, nanoparticles(H-BLFnp) were obtained via vacuum freeze drying. The appearance, performance and structural characterization of H-BLFnp were characterized by particle size analysis, TEM, UV, FTIR, TG and DSC. The results showed that H-BLFnp was a kind of white powder, which had smooth surface and uniform color. The average particle size was(679±10.2) nm with a dispersion coefficient of 0.349?0.004. The encapsulation efficiency of H-BLFnp was 92.39%±0.34%.
