To fabricate stable sized and shaped controlled release delivery systems for salvianolic acid B (Sal B), different food gums were individually added to short-chain glucan solution to prepare starch nanoparticles (StNPs)/gum nanocomposites by self-assembly, and Sal B was embedded in situ. The results showed that size of StNPs was reduced to ca. 45nm with the addition of chitosan and rosin, which decreased by over 50% than that of StNPs without the gum. The StNPs/guar gum nanocomposites had the largest size (109.2nm) among samples of StNPs with gums. The StNPs with chitosan and gum arabic exhibited an obvious core-shell structure. The loading capacities of Sal B in StNPs, StNPs/chitosan, and StNPs/gum arabic nanocomposites were 5.2, 8.26 and 8.08%, respectively. The in vitro release of Sal B from StNPs/gum nanocomposites were sustained and prolonged for over 12h, indicating that StNPs/gum nanocomposites are good candidates to control Sal B release.
为了制备丹参酸 B（Sal B）稳定尺寸和形状的控制释放给药系统，将不同的食用胶单独添加到短链葡聚糖溶液中，通过自组装制备淀粉纳米颗粒（StNPs）/胶纳米复合材料，并将 Sal B 原位嵌入。结果表明，加入壳聚糖和松香后，StNPs 的粒径减小到约 45nm，比没有胶的 StNPs 减小了 50%以上。在含有胶的 StNPs 样品中，StNPs/瓜尔胶纳米复合材料的粒径最大（109.2nm）。StNPs 与壳聚糖和阿拉伯胶表现出明显的核壳结构。StNPs、StNPs/壳聚糖和 StNPs/阿拉伯胶纳米复合材料中 Sal B 的载药量分别为 5.2%、8.26%和 8.08%。StNPs/胶纳米复合材料中 Sal B 的体外释放持续且延长超过 12h，表明 StNPs/胶纳米复合材料是控制 Sal B 释放的良好候选材料。
