目的: 研究丹参传统饮片水煎液和破壁饮片混悬液中隐丹参酮及其代谢物丹参酮IIA的人体药代动力学及生物等效性。方法: 24名健康受试者,男女各半,分别交叉单剂量口服试验药物或参比药物,用LC-MS法测定隐丹参酮,丹参酮IIA的血药浓度,用DAS Ver3.2.2进行数据处理、SPSS进行统计分析。AUC 0-60、C max经对数转换后,进行双单侧t检验并计算其90%可信区间。结果: 隐丹参酮、丹参酮IIA的药代动力学参数T max、C max、AUC 0-60和t 1/2在不同周期和不同性别间差异无统计学意义(P>0.05),在两种制剂间的差异有统计学意义(P<0.05)。受试者单次空腹口服试验药物和参比药物后隐丹参酮及其代谢产物丹参酮IIA试验药物和参比药物的相对生物利用度F分别为(4 456.8±3 706.8)%、(4 690.3±3 416.7)%。结论: 破壁饮片混悬液中隐丹参酮,丹参酮IIA的生物利用度显著高于传统饮片水煎液,临床应用中可以减少给药剂量。 相似文献

An efficient method for quality control of Fructus Aurantii Immaturus (FAI), a famous traditional Chinese medicine (TCM) was established. A simple and reliable high-performance liquid chromatography-photodiode
array detector (HPLC-DAD) procedure coupled with chemometric methods was developed for fingerprint analysis, qualitative analysis
and quantitative determination of this herb. In qualitative and quantitative analyses, heuristic evolving latent projection
(HELP) method was employed to resolve the overlapping peaks of the tested samples. Two bioactive components, namely hesperidin
and naringin, are confirmed and determined, together with four flavonoids compounds tentatively identified including two new
ones. From fingerprint analysis, the fingerprint data were processed with correlation coefficients for quantitative expression
of their similarity and dissimilarity. The developed method based on an integration of chromatographic fingerprint and quantitative
analysis is scientific, and the obtained results can be applied to the quality control of herb medicine. 相似文献

通过比较三七超微粉体、细粉(三七常规饮片)以及不同目数范围粉体(三七细粉经多次筛分得到的粉体)在粒度分布、显微形貌特征方面的差异,探讨了超微粉碎技术应用于中药三七加工的优势。应用激光粒度分析仪对三七超微粉体与细粉、不同目数范围粉体的粒度及其分布进行表征,观察其显微形貌特征。粒度分布测试和显微形貌观察的结果表明,超微粉粒度分布在0.30~24μm,大部分粉体达到了10μm以下,呈对称的单峰分布,引起团聚的作用力为各种表面力,说明超微粉体均匀度高质量易控。三七细粉及不同目数范围的粉体粒度分布范围在2~190μm,分布不对称,引起团聚的作用力为重力的等质量力,说明其均匀度差,质量难以控制。 相似文献
