Objective:To compare the analgesic effect and effective fractions of wild and cultivated Psammosilene tunicoides.Method:compounds of different polarity from roots of wild and cultivated P.tunicoides were extracted
hot plate test and acetic acid writhing test were used in mice for evaluating analgesic effect of the extracts.Result:The extracts of wild and cultivated P.tunicoides produced the similar analgesic effect;both of them contained highly active analgesic ingredients.For the inhibitory effect of the extracts on chemical stimulation induced pain
the active ingredients of wild and cultivated P.tunicoides were found in the parts of n-butanol
ethyl acetate and petroleum.But the ethyl acetate part of artificial cultivation sample had a significant analgesic activity better than that of the wild sample(P<0.05).For the analgesic effect on thermal stimulation induced pain model
the effective fractions of wild P.tunicoides was the n-butanol part
the n-butanol and ethyl acetate parts were in cultivation sample.Conclusion:The artificial cultivation and wild herbs of P.tunicoides
haas the different active ingredients of analgesic function
but their analgesic efficacy do not show a significant difference.So the cultivated P.tunicoides could be used as the equivalent analgesic medicine to substitute the wild herbs.
