Properties and stability
By Streptomyces aureus Strepto-myces aureofaciensExtracted broad-spectrum antibiotics. Melting point170～ 175℃. Optical rotation-239 (Methanol). Slightly soluble in Water, slightly soluble in ethanol, insoluble in chloroform and acetate ether. Stable in the air, color changes under strong light Deep, rapid failure in alkaline solutions.
Storage method
This product should be sealed in0 Store in a dry place below ℃ and away from light.
Synthesis method
None yet
Purpose
On Gram Positive and negative bacteria, protozoa, mycoplasma, and spirochetes all have antibacterial effects. Oral absorption is incomplete,2～4hPlasma concentration reaches peak value and is widely distributed. Mainly excreted through urine and feces. Currently it is rarely used clinically.
