杨树花的活性成分和药理作用及口服液质控技术研究进展OA

Poplar flower has the effects of clearing away heat and toxin,eliminating dampness and stopping dysentery,and is mainly used to treat dysentery,enteritis and other diseases.Its effective components main-ly include flavonoids,phenolic glycosides,phytosterols and so on.It has significant antibacterial,anti-in-flammatory,antioxidant and anti-tumor effects.Modern research shows that the extract of poplar flower has a good inhibitory effect on a variety of pathogens,such as Staphylococcus aureus,Escherichia coli,Sal-monella and so on.Based on its various pharmacological effects,yangshuhua oral liquid has a long history of clinical application in livestock and poultry,and its application scope is more and more extensive,which has a good application prospect.In addition,the quality control techniques of yangshuhua and yangshuhua oral liquid mainly include thin-layer identification,pH value,relative density,absorbance and other aspects,lac-king quantitative control standards for the content of effective components.The data showed that the active ingredients and illegal additives of yangshuhua oral liquid could be determined by HPLC,and the standard of its characteristic spectrum could be formulated,so as to standardize and improve the production quality of yangshuhua oral liquid.
