乳消康胶囊的制备工艺及质量标准研究

目的优化乳消康胶囊的制备工艺,提升乳消康胶囊的质量标准。方法采用正交实验法考察优化乳消康胶囊的水提取工艺;在显微镜下观察香附和枳壳的显微特征;采用TLC法对青皮、香附、丹参、当归、川芎、枳壳和甘草进行研究;采用HPLC法同时测定青皮和枳壳中主要成分柚皮苷和橙皮苷的含量。结果优化后的制备工艺简单可行,香附和枳壳显微特征明显,青皮、香附、丹参、当归、川芎、枳壳和甘草的TLC斑点清晰,阴性对照无干扰。柚皮苷和橙皮苷的质量浓度分别在4.89~97.8和16.8~168μg·mL-1范围内与峰面积呈良好的线性关系(r=0.999 8)。柚皮苷和橙皮苷的平均回收率分别为99.56%和99.50%,RSD值分别为1.58%和0.79%(n=9)。结论制备工艺科学合理,质量标准方法易于操作、专属性强、重复性好,所建立的质量标准可用于该制剂的质量控制。

THE STUDY OF DIFFERENCE OF PCNA LABELLED CELL INDEXES BETWEEN ENDOMETRIA OF HUMAN AND MOUSE

40 human endometrial tissues of benign diseases were diviided into 8 groups (phases),and 50 BDF1 mousy endometrial tissues were divided into 5 groups (phases).Immunohistochenical staining was performed to show the PCNA (proliferating cell nuclear antigen)positive cell .In human ,the results suggested that the PCNA layer(48%)of mid-proliferative hpase.The PCNA labelled index was low in superficial epithelium.But in mouse, the results suggested that the Pcna labelled index was the highest(22%)in endometrium of estrus and the labelled cells were distributed mainly in superficial epithelium (60%).The results suggested that times that times and positions of cellular proliferation in endometrial tissues of human and mouse differed greatly.
