吉他霉素(Kitasamycin)系大环内酯类多组分抗生素,主要对革兰阳性球菌有较好的抗菌作用,对部分革兰阴性菌有一定抗菌作用。 本品在我省已正式生产,为控制产品质量,在新产品2年试行期内,急需制备一批地方标准品以测定产品效价。本研究系通过与标准品的对比分析,建立吉他霉素地方标准品。 Kitasamycin is a macrolide multi-component antibiotic that has good antibacterial activity against gram-positive cocci and some antibacterial activity against some gram-negative bacteria. This product has been formally produced in our province. In order to control the product quality, during the 2-year trial period of new products, it is urgent to prepare a batch of local standards to determine the product potency. In this study, through the comparative analysis with standard products, the local standard of gemcitabine was established.
