不同产地北细辛和华细辛镇痛抗炎药效学评价

目的:进行不同产地的北细辛和华细辛镇痛抗炎药效学评价。方法:以醋酸扭体试验、热板试验对细辛进行镇痛作用评价;以二甲苯致鼠耳肿胀试验对细辛进行抗炎作用评价。结果:12个不同产地的北细辛和华细辛样品均有镇痛和抗炎作用,疼痛抑制率7个北细辛样品在27%～61%,5个华细辛样品在40%～59%。6个产地北细辛的炎症抑制率(50%～70%)强于5个产地的华细辛炎症抑制率(34%～48%)。不同产地同一品种的细辛镇痛抗炎作用差异显著。北细辛:醋酸扭体实验结果显示4个吉林产细辛镇痛作用(38%～57%)均强于黑龙江产细辛(34%);热板实验结果显示黑龙江产细辛镇痛作用(43%)强于2个辽宁产细辛(29%～36%)。华细辛:醋酸扭体实验显示3个陕西产细辛镇痛作用(47%～49%)均强于湖北产细辛(40%);热板实验显示3个陕西产细辛镇痛作用(45%～59%)强于重庆产细辛(40%)。鼠耳肿胀实验结果显示北细辛4个吉林产细辛抗炎作用(51%～63%)均优于黑龙江产细辛(50%)。道地性分析表明,北细辛及华细辛道地药材的镇痛作用有强于各自非道地药材的趋势;北细辛道地药材的抗炎作用较非道地药材强,但华细辛道地药材和非道地药材在抗炎作用方面无明显差异。结论:不同产地的细辛均有镇痛抗炎作用,但作用强度明显不同,显示细辛具有一定程度的道地性。

Assessment on anti-nociception and anti-inflammation pharmacodynamics of Asarum heterotropoides var. mandshuricum and Asarum sieboldii

Objective: To assess the anti-nociception and anti-inflammation pharmacodynamics of Asarum heterotropoides var. mandshuricum and A. sieboldii. Method: Both the writhing test and hot plate test were conducted to assess the anti-nociceptive effect of Asarum and Xylene-induced mouse ear edema was conducted to assess the anti-inflammatory effect of Asarum. Result: Twelve samples of A. heterotropoides var. mandshuricum and A. sieboldii from different producing areas showed anti-nociceptive and anti-inflammatory effects. Specifically, 27% to 61% of the seven samples of A. heterotropoides var. mandshuricum showed anti-nociceptive effect and while 34% to 48% of A. sieboldi showed anti-nociceptive effect. The inflammatory inhibition rate of A. heterotropoides var. mandshuricum produced in six producing areas (38%-57%) is higher than that of A. heterotropoides var. mandshuricum produced in five producing areas (34%-48%). The same kind of Asarum produced in different areas showed significant differences. A. heterotropoides var. mandshuricum produced in Jilin province (38%-57%) showed better anti-nociceptive effect than sample produced in Heilongjiang province (34%) in writhing test. A. heterotropoides var. mandshuricum produced in Heilongjiang (43%) province showed a better anti-nociceptive effect than samples produced in Liaoning province (29%-36%) in hot plate test.,A. sieboldii produced in Shaanxi province (47%-49%) showed a better anti-nociceptive effect than samples produced in Hubei province (40%) in writhing test.,A. sieboldii produced in Shaanxi province (45%-59%) showed better anti-nociceptive effect than samples produced in Chongqing (40%) in hot plate test. A. heterotropoides var. mandshuricum produced in Jilin province (51%-63%) showed better anti-inflammatory effect than samples produced in Heilongjiang province (50%). In totality, the results from analysis of geoherbalism showed that famous-region A. heterotropoides var. mandshuricum and A. sieboldii had a better anti-nociception effect than Asarum produced in other producing areas. famous-region A. heterotropoides var. mandshuricum had a better effect than those produced in other producing areas in anti-inflammation. But famous-region A. sieboldii showed no obvious difference from those produced in other producing areas in anti-inflammation. Conclusion: All samples of Asarum showed anti-nociceptive and anti-inflammatory effects, but with significant differences among Asarum produced in different areas, indicating the eoherbalism to some extent.
