目的:制备原花青素/白芨多糖/壳聚糖微球并对其理化特性进行考察。方法采用喷雾干燥法制备原花青素/白芨多糖/壳聚糖微球,扫描电镜观察不同药物载体比例微球的粒径、外观,并对其体外释放、含水率、溶胀率、固密度等理化特性进行考察。结果喷雾干燥法成功构建原花青素/白芨多糖/壳聚糖微球A、B、C3种微球,电镜结果显示原花青素/白芨多糖/壳聚糖微球平均外观圆整,表面有褶皱,粒径在2~15μm分布均匀;体外释放结果表明,原花青素A、B、C 3种微球累计释放分别为25.07%、38.83%和60.00%,无突释现象;原花青素24 h时累计释放分别为28.42%、41.82%和67.52%,48 h累计释放分别为28.89%、43.17%和72.86%,微球具有缓释作用。含水率、溶胀率、固密度结果分为15.35%~23.51%、46.50%~105.80%、0.375~0.496。结论喷雾干燥法成功构建原花青素/白芨多糖/壳聚糖微球,微球表面有褶皱,粒径固密度、溶胀等特性良好,具有缓释作用,有望成为肺吸入给药的良好载体。
目的:製備原花青素/白芨多糖/殼聚糖微毬併對其理化特性進行攷察。方法採用噴霧榦燥法製備原花青素/白芨多糖/殼聚糖微毬,掃描電鏡觀察不同藥物載體比例微毬的粒徑、外觀,併對其體外釋放、含水率、溶脹率、固密度等理化特性進行攷察。結果噴霧榦燥法成功構建原花青素/白芨多糖/殼聚糖微毬A、B、C3種微毬,電鏡結果顯示原花青素/白芨多糖/殼聚糖微毬平均外觀圓整,錶麵有褶皺,粒徑在2~15μm分佈均勻;體外釋放結果錶明,原花青素A、B、C 3種微毬纍計釋放分彆為25.07%、38.83%和60.00%,無突釋現象;原花青素24 h時纍計釋放分彆為28.42%、41.82%和67.52%,48 h纍計釋放分彆為28.89%、43.17%和72.86%,微毬具有緩釋作用。含水率、溶脹率、固密度結果分為15.35%~23.51%、46.50%~105.80%、0.375~0.496。結論噴霧榦燥法成功構建原花青素/白芨多糖/殼聚糖微毬,微毬錶麵有褶皺,粒徑固密度、溶脹等特性良好,具有緩釋作用,有望成為肺吸入給藥的良好載體。

Objective To prepare proanthocyanidins/bletilla striata polysaccharide/chitosan microspheres ( PC/BSP/CTS ) and the physic-chemical characterizations were investigated.Methods The PC/BSP/CTS microspheres were prepared by spray drying method.The morphology of PC/BSP/CTS microspheres was observed by Scanning Electron Microscopy(SEM), and its physic-chemical characteristics such as diameters, release in vitro, moisture content, swelling ratio, solid density were studied.ResuIts The PC/BSP/CTS microspheres were successfully prepared by spray drying method, SEM showed that PC/BSP/CTS microspheres had the spherical shape with smooth surfaces.The diameters of microsphere A, B and C were 10~20, 2~15, 10~25μm.The in-vitro release showed that the cumulative release of three kinds of microspheres A, B, C was 25.07 %, 38.83 %and 60.00 % in 24 h, which had no burst release, while with time prolonged to 48 h, the cumulative release was 28.89%, 43.17% and 72.86%, respectively.The results of moisture content, swelling ratio, solid density were 15.35% ~23.51%, 46.50% ~105.80%, 0.375 ~0.496. ConcIusion The PC/BSP/CTS microspheres are successfully prepared by spray drying method which possess good characteristics and sustained-release effect, which would be as a good pulmonary drug delivery system.
