桑蒺颗粒中陈皮、枳壳挥发油的提取及β-环糊精包合工艺
Chinese Journal of Hospital Pharmacy(2017)
Abstract
目的:优选桑蒺颗粒中陈皮、枳壳挥发油的最佳提取及包合工艺.方法:采用正交试验法,以挥发油提取量为评价指标,优化加水量、浸泡时间和提取时间3个因素,优选挥发油提取工艺;以挥发油包合率和包合物收率为评价指标,优化挥发油∶β-环糊精(β-CD)、包合温度和包合时间,优选挥发油包合工艺;采用显微镜、薄层色谱及加速试验对所得包合物进行表征.结果:桑蒺颗粒中陈皮、枳壳挥发油的最佳提取工艺为加8倍量水,浸泡0.5 h,提取6 h;最佳包合工艺为挥发油与β-CD比例1∶10,在40℃下包合0).5 h;3项表征试验均证实挥发油已包合于β-CD内.结论:优选的桑蒺颗粒中陈皮、枳壳挥发油的最佳提取及包合工艺稳定可行.
