摘 要 目的:制备白屈菜红碱(CHE)固体分散体(SD),优化其处方工艺,并对所制产品进行表征和体外抗氧化活性考察。方
法:采用紫外分光光度法测定SD中CHE的含量;在单因素试验的基础上,以产品收率为指标,以制备方法、载体材料种类、载体比
例(药物-载体材料质量比)为考察因素,采用L9 (3)正交试验优化SD的处方工艺并进行验证。在检测溶解度和累积溶出度的基础

上,采用热分析法、X-射线衍射法和扫描电子显微镜等技术对产品进行物相表征;以抗坏血酸为阳性对照,采用1,1-二苯基-2-三
硝基苯肼法(DPPH)测定产品的体外抗氧化活性。结果:CHE检测质量浓度的线性范围为2.4~5.6 μg/mL,定量限、检测限分别为
0.066 9、0.022 1 μg/mL;精密度、稳定性、重复性试验的RSD均小于2%,加样回收率为97.50%~99.25%(RSD<1%,n=3)。最优
制备工艺是以聚乙二醇6000(PEG 6000)为载体、载体比例为1 ∶ 3,采用溶剂法制备。按最优工艺制得3批CHE-PEG-SD,验证试
验结果显示,其在15 min时的累积溶出度为(61.72±0.67)%,收率为(99.04±0.83)%。表征结果显示,制成CHE-PEG-SD后,其
溶解度(3.725 mg/mL)和累积溶出度(61.72%,15 min)均高于CHE原料药[0.098 mg/mL,6.24%(180 min)];其吸热峰、晶体吸收峰
均较原料药和载体有所移动甚至消失,CHE 以非晶态均匀分散于载体中。体外抗氧化试验结果显示,不同质量浓度的
CHE-PEG-SD均具有一定的DPPH自由基清除能力,半数抑制浓度为0.124 mg/mL,但高于抗坏血酸的0.041 mg/mL。结论:所建
含量测定方法简便、准确;优化的SD处方工艺稳定、可行;所制CHE-PEG-SD的溶解度增大,体外溶出增多,且具有一定的体外抗

ABSTRACT OBJECTIVE:To prepare Chelerythrine (CHE) solid dispersion (SD),optimize the formulation technology,
characterize its preparation and investigate its in vitro antioxidant activity. METHODS:The content of CHE in SD was determined
by UV spectrophotometry. Based on single factor tests,using the product yield as index,using preparation method,carrier material
type,carrier material proportion(drug-carrier material mass ratio)as factors,the formulation technology of SD was optimized by
L9 (3)orthogonal test and validated. Based on solubility and accumulative dissolution determination,the product was characterized
4
with thermal analyssis,X-ray diffraction and scanning electron microscope. Using ascorbic acid as positive control,in vitro
antioxidant activity of the product was determined by DPPH method. RESULTS:The linear range of CHE was 2.4-5.6 μg/mL;
quantitation limit and detection limit were 0.066 9,0.022 1 μg/mL;RSDs of precision,stability and reproducibility tests were all
lower than 2%;recoveries were 97.50%-99.25%(RSD<1%,
