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%。

Abstract: 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 0.3490.004. The encapsulation efficiency
of H-BLFnp was 92.39%±0.34%.
