1、醋曲片的最佳制备工艺与质量控制,硕士论文高脂血症导致的心血管疾病在近年来发病率越来越高。其造成血脉壁的淤 积,极易产生急性冠心病和动脉粥样硬化性心血管疾病。为了减少心血管疾病的 发生,降脂治疗和预防势在必行。近年来,来源天然的降脂产品备受消费者的关 注。 本研究制备的醋曲片由醋粉、红曲和芦荟组成,用于降血脂,其疗效确切且 具有较好的安全性。 制剂中醋粉和红曲以粉末入药,芦荟经醇提浓缩枯燥之后入药。首先对芦荟 的提取工艺进行研究,采用乙醇加热回流提取法,选取乙醇浓度、提取时间、液 料比为考察因素,以黄酮类化合物的吸光度值R1和浸膏得率R2为评价指 标,采用响应曲面法对芦荟中总黄酮提取工艺进行优化
2、,确定最佳提取工艺为: 65%乙醇作提取溶剂,液料比为 20:1,回流提取 4 h,对提取液中的乙醇进行回 收,浓缩物于 60 烘箱中枯燥。 醋曲片片芯的制备采用湿法制粒压片,通过单因素考察发现崩解剂用量、润 湿剂浓度和枯燥温度对片芯质量影响较大,因而以上述三种变量为考察因素,以 片芯的崩解时间、硬度、外观和压片前颗粒的休止角等指标的综合评分作为成型 工艺的评价指标,采用正交试验设计对崩解剂用量、润湿剂浓度和枯燥温度进行 优化,确定了最优片芯1000 片处方为:醋粉470 g,红曲200 g,芦 荟280 g,预胶化淀粉75 g,聚乙烯吡咯烷酮25 g,85%乙醇溶液适 量,滑石粉10 g。
3、醋曲片中含挥发性和易吸湿性成分,因而片剂外包薄膜衣。选取包衣温度、 包衣液供应速率和包衣增重三个变量为考察因素,以所得包衣片的合格率和崩解 时间作为评价指标,采用 Box-Behnken 试验设计方案,对选取的三个包衣工艺参 数进行挑选。确定了最佳包衣工艺为:取适量薄膜包衣预混剂于纯化水中溶解, 制得固含量为 12%的包衣液,包衣温度为 45 ,包衣液供应速率为 4 mL/min, 包衣增重为 3%. 本研究建立了醋曲片的质量标准:采用显微鉴别法和薄层色谱法对醋曲片中 的红曲进行定性鉴别,采用薄层色谱法对醋曲片中的芦荟进行定性鉴别,以上药 材均检出且特征明显。采用高效液相色谱法测定醋曲片中总洛
4、伐他汀的含量,经 方式方法学验证,各项指标均符合相关规定,本研究建立的定性、定量方式方法准确可靠。 本论文确立了醋曲片的最佳制备工艺,经中试试验验证,工艺稳定可行。醋 曲片中的洛伐他汀含量高,用于降血脂疗效显著,因而以总洛伐他汀作为质量控 制的指标成分。经影响因素试验、加速试验及长期试验考察,结果表示清楚,醋曲片 稳定性良好。 本文关键词语:醋曲片,制备工艺,质量标准,洛伐他汀,稳定性 Abstract The incidence rate of cardiovascular disease caused by hyperlipemia has been increasing in recen
