An preliminary comparative study on physiological activity of Fritillaria pallidiflora Schrek. and F. delavayi Franch

Objective:To compare the physiological activity of Fritillaria pallidiflora alkaloids(FPA)with that of F. delavayi alkaloids(FDA).Method:Xylene induced ear swelling in mice,SO 2 induced cough in mice,expectorant experiment on phenolsulfon phthalein excretion and bacteria incubation in vitro,etc. Result:The total alkaloids of both FPA and FDA(ig,400mg·kg -1 and 200mg·kg -1 )have anti inflammatory,antibechic and expectorant effects,but the former is more effective than the latter.Given the same dosage,FPA is still more effective than FDA.FPA can inhibit Hemophilus influenzae, Staphylococcus aureus and Streptococcus pneumoniae,etc,more effectively than FDA.Conclusion:In anti inflammatory,antibechic,expectorant and bacteriostatic effects FPA is superior to FDA.
