成人本科毕业论文 丹参酮IIa磺酸钠微量杂质的分离及结构鉴定 目 录 摘要参考文献致谢丹参酮IIa磺酸钠微量杂质的分离及结构鉴定： Separation of Microimpurity and Identification of Sodium Tanshinone IIa Sulfonate Abstract: Salvia miltiorrhiza is one of the most important tradition Chinese medicinal materials that possess the function of both promoting blood flow and removing blood stasis with anti-coronary artery disease. The consumed quantity only in the aspect of injection has been exceeded 2 billion dosages every year. However, because the undetermined active ingredients and relaxed index of quality control induced the instable effects of clinic traterment, and, moreover, usually adverse functions, which lead salvia miltiorrhiza unable to accommodate requirement of contemporary Chinese medicinal materials melting world. Sulfotanshinone sodium is asodium chloride of water-solubility after sulfonating tanshinone IIa of liposolubility active ingredien tabstraeted in salvia miltiorrhiza.It is an effective medicine of angiocardiopathy to treat coronary artery disease, anginacordis，and myocardial infarction.The amount of clincal utilization continuous. increasing with the high proportion of patients of angiocardiopathy induces raw material resource of salvia miltiorrhiza insufficient in China. So it becomes an extensive focus point in fharmaceutical factory that sufficient utilize and cut down uymost dissipation resource of salvia miltiorrhiza.
