Abstract:
6,7-dicho- methoxyl-8-Hydroxycoumarin. Fraxinus rhynchophylla Hance extract had obvious bacteriostasis to 9 kinds of bacterium;monomer mixture and coumarin fingerprint region sample had obvious bacteriostasis to Staphylococcus aureus, Staphylococcus epidermidis, beta streptococcus, aeruginosus Bacillus, Bacillus coli, Klebsiella pneumoniae, catarrh. Unknown component fingerprint region sample had obvious bacteriostasis to Staphylococcus aureus and certain bacteriostasis to Staphylococcus epidermidis, alpha streptococcus, beta streptococcus, Bacillus coli, salmonella. Conclusion The changes of ash bark bacteriostasis were basically identical with known coumarin component content. Aglycone bacteriostasis of ash bark was superior to glycoside, fraxetin and aesculetin bacteriostasis were most powerful in 5 kinds of coumarin monomer.
