中文摘要:
      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)的阳离子桥键合而成竹叶碳苷黄酮纳米混悬液(H-BLFnd),进一步在混悬液中添加8%(w/v)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)%。
英文摘要:
      The nanodrop(H-BLFnd)was 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 as raw materials, ε-polylysine as a cross-linking agent, then 8 % (w/v) of γ-cyclodextrin was added to H-BLFnd as protective agent, and nanoparticle (H-BLFnp) was obtained via vacuum freeze drying. The appearance, performance and structural characterization of H-BLFnp were tested through particle size analysis, TEM, UV, FTIR, TG and DSC. Results showed that H-BLFnp is a kind of white powder, smoothly and uniformly, which is of(679±10.2)nm average size, (0.349±0.004)dispersion coefficient and(92.39±0.34)% encapsulation efficiency.
