                 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 0.3490.004. The encapsulation efficiency
                 of  H-BLFnp was 92.39%±0.34%.
