摘要:采用小鼠扭體試驗(yàn)、熱板法、二甲苯致耳朵腫脹法和角叉菜膠致足腫脹法研究了九里香[Murraya exotica(L.)]葉的鎮(zhèn)痛抗炎作用。結(jié)果表明,九里香葉醇提物可有效抑制醋酸致小鼠的扭體反應(yīng),延長(zhǎng)小鼠的痛閾值,顯著抑制二甲苯及角叉菜膠誘導(dǎo)的腫脹。表明中藥九里香葉醇提物具有顯著的抗炎、鎮(zhèn)痛藥理學(xué)作用,為中藥九里香的二次開(kāi)發(fā)提供了有益的科學(xué)依據(jù)。

Abstract: The study of anti-inflammatory and analgesic activities of Murraya exotica(L.) was performed with the mouse body-torsion test, hot-plate test, xylene-induced ear edema test, and carrageenan-induced paw swelling test. The results showed that the ethanol extract of the M. exotica leaves could effectively inhibit the writhing reaction induced by acetic acid, prolong the threshold time of pain, and significantly inhibit the edema induced by xylene and carrageenan. It indicated that the ethanol extract of the M. exotica leaves possesed the anti-inflammatory and analgesic activities. The study provided useful information for the “second” exploitation of M. exotica.
Key words: Murraya exotica(L.);anti-inflammatory; analgesic
九里香[Murraya exotica(L.)]又稱千里香、滿山香、過(guò)山香、千只眼等,為蕓香科九里香屬植物,以根和葉入藥,性辛、苦、微寒。具有行氣止痛、活血化瘀、祛風(fēng)除濕、麻醉鎮(zhèn)驚等功效。早期曾有報(bào)道,九里香在臨床上可用于局部麻醉、抗生育作用[1]、治療流行性乙型腦炎、破傷風(fēng)、急、慢性腎炎等。現(xiàn)代藥理學(xué)研究表明,九里香具有抗生育和終止妊娠、抗菌、抗甲狀腺腫大、降血糖、麻醉鎮(zhèn)靜及增強(qiáng)免疫功能等作用,但未見(jiàn)有對(duì)九里香的抗炎鎮(zhèn)痛等生物學(xué)活性的研究報(bào)道。本試驗(yàn)采用小鼠扭體試驗(yàn)、熱板法、二甲苯致耳朵腫脹法和角叉菜膠致足腫脹法研究了九里香葉的鎮(zhèn)痛抗炎作用,為中藥九里香的二次開(kāi)發(fā)提供了有益的科學(xué)依據(jù)。
1材料
1.1藥材
九里香采自福建省漳州市,經(jīng)華僑大學(xué)分子藥物學(xué)研究所張景紅教授鑒定為九里香,自然陰干,機(jī)械粉碎過(guò)40目篩。石油醚、乙醚、乙酸乙酯、氯仿、乙醇及二甲苯等均為分析純。
1.2試驗(yàn)動(dòng)物
昆明小鼠,雌雄兼用,體重為(20±2)g。均由福建醫(yī)科大學(xué)實(shí)驗(yàn)動(dòng)物中心提供,合格證號(hào):SCX(閩)2004-002。……
