摘 要 目的 制备芎芷石膏汤可溶性微针,并进行表征及体外透皮性能考察。方法 采用两步离心法制备芎芷石膏汤可溶性微
针,并从基质溶液流动性、微针成形性、针尖硬度等方面评价其成形性和机械性能。以该可溶性微针的活性成分(绿原酸、阿魏酸、
羌活醇、欧前胡素、藁本内酯、异欧前胡素)为考察指标,从外观形态、机械强度、溶解性能、皮肤屏障恢复性能、载药量进行表征,并
采用Franz扩散池法考察其体外透皮性能。结果 本研究所制备的芎芷石膏汤可溶性微针针尖呈圆锥形,分布均匀且粗细相同,机
械性能良好;针尖部分可在刺入大鼠皮肤2 h后几乎全部溶解,且皮肤屏障恢复性能良好;微针中绿原酸、阿魏酸、羌活醇、欧前胡
素、藁本内酯、异欧前胡素的载药量分别为每片(87.04±1.12)、(67.69±1.23)、(20.65±0.17)、(35.00±0.11)、(153.83±0.21)、
(23.52±0.50) μg。体外透皮实验结果显示,该微针中 6 种活性成分 72 h 的累积释放率分别为 36.94%、56.72%、19.36%、57.98%、
11.06%、35.19%。结论 本研究成功制备了芎芷石膏汤可溶性微针,其成形性、机械性好,背衬柔韧,可促进药物透皮吸收。

ABSTRACT OBJECTIVE To prepare Xiongzhi shigao decoction soluble microneedles, characterize it and investigate its
transdermal properties in vitro. METHODS Two-step centrifugal method was used to prepare Xiongzhi shigao decoction soluble
microneedles. The formability and mechanical property of the microneedles were evaluated from aspects of stroma fluidity,
microneedle formability, needle hardness, etc. The appearance, mechanical strength, dissolution performance, skin barrier
recovery performance and drug loading of the prepared microneedles were characterized by using active components of the soluble
microneedle (chlorogenic acid, ferulic acid, notopterol, imperatorin, ligustilide, isoimperatorin) as indicators. The in vitro
transdermal performance was investigated by Franz diffusion cell. RESULTS The soluble microneedle tips of Xiongzhi shigao
decoction prepared in this study were conical, evenly distributed and of the same thickness, with good mechanical properties; the
tip of the needle could be almost completely dissolved after being penetrated into the skin of rats for 2 hours, and the skin barrier
recovery performance was good; the drug loading of chlorogenic acid, ferulic acid, notopterol, imperatorin, ligustilide and
isoimperatorin were (87.04±1.12), (67.69±1.23), (20.65±0.17), (35.00±0.11), (153.83±0.21) and (23.52±0.50) μg per
patch respectively. The results of in vitro transdermal study showed that cumulative release rates of 6 active components in this
microneedle after 72 hours were 36.94%, 56.72%, 19.36%, 57.98%, 11.06% and 35.19%, respectively. CONCLUSIONS
Xiongzhi shigao decoction soluble microneedles are prepared successfully in this study and have good formability, mechanical
properties and pliable backing, which can significantly promote the transdermal drug delivery.
